FutureForge is a strategic programme in the University of Strathclyde Advanced Forming Research Centre (AFRC) to deliver a 2,000 Tonne hydraulic press acting in three forging modes; open die, closed die and isothermal mode. A key element of FutureForge relates to the development of a digital environment and simulation capability. The forging enviro...

The Foucault pendulum has become one of the fundamental experiments of physics since Léon Foucault’s famous demonstration of a 67-metre pendulum with a 22 kg bob mass at the Panthéon in Paris in 1851. This paper attempts to show that Foucault’s fundamental experiment could perhaps be developed into a highly sensitive measurement system capable of r...

The pendulum applied to the field of mechanical energy harvesting has been studied extensively in the past. However, systems examined to date have largely comprised simple pendulums limited to planar motion and to correspondingly limited degrees of excitational freedom. In order to remove these limitations and thus cover a broader range of use, thi...

Aluminium composite sandwich panels are widely used to enhance the design of structures subjected to dynamic mechanical loading in thermally harsh environments. Spacecraft structures fall into this category because typical environmental conditions include combined and variable mechanical and thermal loading. Usually mechanical loadings arise as a c...

The topic of Symbolic Computational Dynamics, as presented here, has been motivated by the utility of approximate analytical solutions for reduced order models, and the power of computers to cope with the challenges of both problem scale and automation. Application has traditionally been limited by the algebra needed for problems of more than a few...

Nonlinear energy harvesters are frequently considered in preference to linear devices because they can potentially overcome the narrow frequency bandwidth limitations inherent to linear variants; however, the possibility of variable harvesting efficiency is raised for the nonlinear case. This paper proposes a rotational energy harvester which may b...

Symbolic computational dynamic solvers are currently under development in order to provide new and powerful tools for modelling nonlinear dynamical systems. Such solvers consist of two parts; the core solver, which comprises an approximate analytical method based on perturbation, averaging, or harmonic balance, and a specialised term-tracker. A ter...

This study deals with nonlinear oscillators whose restoring force has a polynomial nonlinearity of the cubic or quadratic type. Conservative unforced oscillators with such a restoring force have closed-form exact solutions in terms of Jacobi elliptic functions. This fact can be used to design the form of the external elliptic-type excitation so tha...

Vibrational energy harvesters are often excited by band-limited noise excitations. In this paper, the influence of the stiffness nonlinearity on the transduction of the energy harvester and the relative performance of linear, monostable hardening-type and bistable energy harvesters are compared and investigated. The performance is experimentally co...

Failures of gearbox components are responsible for more than 20% of the downtime of wind turbines . Real operational conditions are more complex when specified in IEC 61400-4 standard thus the real loading maybe under estimated in the design calculations.Common design practice reduces wind turbine drivetrain dynamic model to simple two or five degr...

The non-linearity of a hardening-type oscillator provides a wider bandwidth and a higher energy harvesting capability under harmonic excitations. Also, both low- and high-energy responses can coexist for the same parameter combinations at relatively high excitation levels. However, if the oscillator’s response happens to coincide with the low-energ...

The elastoplastic impact response of a trimorph plate subjected to low-velocity large mass impact has been investigated using analytical models. In formulating the impact model, the displacement of the impactor, vibration of the plate and local contact mechanics were accounted for. The vibration of the trimorph plate was modelled using the classica...

This paper proposes a novel model to harvest energy from automotive tyre rotation, based around the principle of stochastic resonance. The model is constructed around the physical premise of positioning a magnetic end mass at the end of a cantilever beam, and in the vicinity of another permanent magnet with the same polarity, and on the frame of a...

There has been much recent interest in the response analysis and optimisation of the linear energy harvester under ambient vibrations. To transfer maximum power to an electrical load in a resonant system, the load resistance should be equal to the sum of the electrical analogue of mechanical damping and internal resistance. However, principally bec...

Stochastic resonance is a physical phenomenon where large vibration occurs when a weak sinusoidal force is applied to a bi-stable system. It is expected that a larger vibrational response can be produced than for a typical resonance. Then the authors utilize this system as an energy harvester, which converts energy from vibration. The energy balanc...

We consider an L-shaped beam structure and derive all the equations of motion considering also the rotary inertia terms. We show that the equations are decoupled in two motions, namely the in-plane bending and out-of-plane bending with torsion. In neglecting the rotary inertia terms the torsional equation for the secondary beam is fully decoupled f...

Linear modal analysis of L-shaped beam structures indicates that there are two independent motions, these are in-plane bending and out of plane motions including bending and torsion. Natural frequencies of the structure can be determined by finding the roots of two transcendental equations which correspond to in-plane and out-of-plane motions. Due...
