    ABSTRACT: Based on the traffic situation, vessel type and atmospheric condition, an inland waterway traffic noise prediction model was developed for environmental assessment in China. This model was developed from the Germany Richtlinien fur den Larmschutz an Strassen (RLS 90) model by adding the water surface condition, absorption and gradient along vessel travel direction correction terms to the governing equations. The re-described parameters, including traffic flow and composition, vessel speed, air absorption, and water surface, ground and atmospheric conditions, etc., were chosen as inputs into the calculating equations. The verification results showed that the absolute error between the predicted and measured noise levels within the range of +/- 1.4 dBA was 82.9%. The mean difference between the predicted and measured noise levels was 0.02 +/- 1.25 dBA. The comparison results with the RLS 90 model and the modified Federal Highway Administration (FHWA) model also showed that the developed model in this study had better precision and accuracy.

    ABSTRACT: The absorbed power characteristics of seated body exposed to whole-body vibration along the individual and combined fore-aft (x), lateral (y) and vertical (z) axes are investigated through measurements of body-seat interactions at the two driving-points formed by the body and the seat-pan, and upper body and the seat backrest. The experiments involved two levels of back support (no back support and vertical backrest) and two levels of broad-band vibration with nearly constant acceleration power spectral density in the 0.5-20 Hz frequency range applied along the individual x-, y- and z- axis (0.25 and 0.4 m/s(2) rms acceleration), and along the three-axis (0.23 and 0.4 m/s(2) rms acceleration along each axis). The biodynamic responses, measured at the seat-pan and the backrest are applied to characterize the total seated body's energy transfer along each axis. Furthermore, an alternative frequency response function method Hi, is employed to capture the coupling in the seated body responses to uncorrelated multi-axis vibration. The total vibration absorbed power responses to simultaneous x, y and z axis vibration are subsequently derived as the summation of vibration absorbed power along the individual axis within each one-third frequency band. The mean responses measured at the seat-pan suggest strong effects of the back support, and the direction and magnitude of vibration. The total vibration power absorbed by the seated body is further estimated under a multi-axis vibration environment of four different work vehicles. The results suggest that total average power absorbed under reported vehicular vibration varies With the effective acceleration in a nearly quadratic manner.

    ABSTRACT: In order to understand the effects of gaseous production on the acoustic radiation characteristics of underwater pyrotechnic combustion, the pyrotechnic combustion pressure-time curves are plotted using a closed bomb and then maximum pressure is used to calculate the quantity of gaseous products. The results show that among the four pyrotechnic compositions with different gas productions, overall sound pressure level (OASPL) and 1/3 octave band sound pressure level (SPL) in composition #4 which has the highest nozzle gas flow, shortest period of bubble formation and largest maximum bubble diameter, reached 165.1 dB and 163 dB respectively, which were 6 dB and 10 dB higher than the corresponding minimum values. During underwater pyrotechnic combustion, bubbles were formed at the nozzle of the combustion device and thus generated low-frequency noise. The increased gas production resulted in a shorter bubble formation period, a larger number of bubbles, and larger bubble diameter, which destabilize the fluid during bubble formation, improve the prone of bubbles to coalescence and breakup, and increase the sound pressure level.

    ABSTRACT: The purpose of this study is to assess the traffic noise (LA(eq)(15 min)) and traffic flow in the Pasdaran road and Keshavarz road of Sanandaj, Iran. The vehicles including car-pickups, minibus-vans, truck-buses and motorcycles passing through the roads are considered. The results show that day average and night average of LA(eq)(15 min) values were 73.34 dBA and 72.59 dBA respectively, higher than the World Health Organisation (WHO) outdoor environmental noise guidelines. The highest mean value of LAeq(15 min) was recorded as 74.05 dBA. It was found, minibus-vans and truck-buses were mainly responsible for producing traffic noise in these roads. In conclusion, the most important element to reduce traffic noise in the two main roads is to impose control programs on the two groups of vehicles. Furthermore, it is suggested to use sound barriers along the two roads of Sanandaj city.

    ABSTRACT: A global noise protective solution, based on the idea of virtual acoustic corridors, dedicated to industrial areas, is investigated. Research studies on decentralized ANC system with several secondary sources and error sensors are performed in the KOMAG Institute of Mining Technology. The models of the electro-acoustic paths are obtained through dynamical systems identification. Experimental results from the proposed active noise reduction system are presented, based on recorded noise signals from the Rybnik Power Plant. Finally, effectiveness and usefulness of hearing protection of such a global system are verified.

    ABSTRACT: A new predictive control approach is employed to control a non-linear 4 degrees of freedom vehicle suspension model including pitch and bounce motions. The front and rear suspension actuator forces are considered as control inputs. These are determined by minimizing a performance index defined as a weighted combination of conflicting objectives, namely ride comfort and road holding. In this way, the suspension deflection and the control forces should be restricted to admissible practical ranges. In this paper, an optimization process is used to develop a multi-input multi-output (MIMO) non-linear control law in a closed-form which is mathematically tractable and suitable for implementation. To investigate special features of the derived control law, the closed-loop system dynamics are first evaluated analytically and then the corresponding simulation results are presented. The results show that a compromise between mentioned objectives and control energy, even in the presence of uncertainties, can be easily made by regulating the control weighting factors.

    ABSTRACT: Thermo-acoustic instabilities are characterized by large-amplitude pressure oscillations, which are detrimental to land-based gas turbine and aero-engines. In this work, a real-time monitoring and feedback control strategy is developed, which involves two algorithms. One is an identification algorithm, which is used to 'sense' the condition of a combustion system and to conduct system identification. The algorithm performs somewhat similar to short-time Fourier transform, but is suitable for real-time computation and is able to more accurately estimate frequency using a shorter sample length. Furthermore it can output a reconstructed signal whose frequency is twice of the input signal, which has great potential to be used for system identification. The other algorithm is a revised infinite impulse response (IIR) filter; its efficiency is optimized by using LMS (least mean square). Finally, the control strategy is then experimentally implemented on a Rijke tube. It is found that approximately 50 dB sound reduction is achieved by actuating a loudspeaker. In addition, the control strategy is demonstrated to be able to track and prevent the onset of new limit cycle results from changes of fuel flow rate.

    ABSTRACT: This paper presents a comprehensive procedure to calculate steady dynamic response and noise radiation generated by a gear reducer. In this process, the bearing force is obtained by solving the transmission system dynamic model, which is taken as the excitation of the gearbox, the noise generated by the gearbox vibration is researched by using FEM/BEM, so the dynamic characteristics of gear transmission and gearbox structure are demonstrated. Then the time history of node dynamic response and noise spectrum of the gearbox are obtained, and the effect of the excitation of frequency doubling of mesh frequency on the gearbox vibration and noise radiation is illustrated. The changes in radiated noise of gear reducers with load are calculated respectively by using both simulation and Kato's formulae, and results agree well with each other. The frequency range of the gearbox resonance is obtained by analyzing the spectral maps of the vibration and noise under the case of engine speed steadily increased. The study provides useful theoretical guideline to the design of the gearbox.

    ABSTRACT: A model predictive controller (MPC) in the form of dynamic matrix control (DMC) is implemented for attenuating in-plane vibrations of a two flexible link planar manipulator. The rotation of the joints and inertia effect of both the joints and links induce vibration. Piezoelectric actuators, mounted in a bimorph configuration, provide the control actions to reduce vibrations. Implementation of this control scheme is shown to provide appreciable attenuation of vibration over the uncontrolled case, increasing the damping ratio for the first and second link by a factor of 5.99 and 3.40, respectively. DMC control is further shown to reduce the mean amplitude of dominant vibrations from the uncontrolled case by 90.0% and 87.4%, respectively, for the first and second links Furthermore, for the two link setup, this control is shown to outperform the more conventional ProportionalIntegral-Derivative (PID) control and is sufficiently robust to handle an unknown payload.
