Research ArticleOpen accessIn the keywordsBi-Stable Vibration Power Generation System Using Electromagnetic Motor and Efficiency Improvement by Stochastic ResonanceWei Zhao, Yoshiro Fujiwara, Jingchao Guan et al.Research on vibration energy harvesting using stochastic resonance has become an important research topic. A vibration energy harvesting system was developed using electromagnetic motors based on an obliquely supported bistable motion model consisting of a spring mass. After formulating the motion-governing equations of the proposed vibrating system and analyzing its potential energy performance, it was demonstrated that the system exhibits … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 3 · 2 Aug 2023 · 5,734 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInteraction of Soil Static and Dynamic Stiffness and Buried Pipeline Under Harmonic VibrationAlireza Mirza Goltabar Roshan, Hossein Khalilpasha, Mohsen GhorbaniProblem statement: When earthquake is occur, many damages were occurred in pipelines that San Francisco (1906) and Manson (1908), Kobe (Japan) and ate are samples of this topic. So many researchers studied on the pipelines and dynamic forces. Approach: Determine static and dynamic performance parameters of the pipeline and the surrounding soil such as static stiffness, dynamic stiffness, damping and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,727 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMorphing Mechanisms Part 2: Using Repetitive Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis research utilizes the repetitive control approach in morphing a high-speed cam mechanism so that its output displacement tracks the desired output trajectory. The main objective is to reduce the output tracking error, which is the difference between the actual and desired output displacements of the output mass. A 3-degree of freedom mathematical model is used to analyze and represent … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,369 accessesView PDF Cite
