The Lookprabida formula student team uses an electronic throttle control (ETC) system in the racecar. Unfortunately, the ETC system cannot regulate the throttle valve to closely pursue angular setpoints. Thus, this paper endeavors to improve the response of the ETC system in racing cars. The ETC system is first examined using frequency response ana...

Soft actuator technology is extensively utilized in robotic manipulation applications. However, several existing designs of soft actuators suffer from drawbacks such as a complex casting process, a multi-air chamber configuration, and insufficient grasping force. In this study, we propose a novel soft bellow design featuring a single air chamber, w...

Since the year 2011 a new wheel hub motor with air gap winding is developed, manufactured and tested at the Faculty of Mechanical Engineering at the "Lehrstuhl für Mechatronik" of the Otto von Guericke University Magdeburg. To investigate the consequences that result from mechanical loads a finite element model has been built up. Typical loads are...

The dual-stage head gimbal assembly of the hard disk drive utilizes the piezoelectric actuator to supplement the voice coil motor for the precision head positioning. Vibration characteristic of the head gimbal assembly system is analyzed by using the finite element method. The modal characteristic of the piezoelectric head gimbal assembly is measur...
