Electric motors replace power sources of conventional mechanical systems used to be driven by hydraulic, pneumatic and/or human power. The replacements cause noise vibration problems mechanical engineers cannot foresee. In this presentation, the concept of physical modeling is introduced and cases of noise/vibration analyses by SimulationX, a physical modeling analysis tool, will be seen. Some models using JMAG-RT files are also introduced.
Noise/vibration problems are effected by shapes of the containers or cases. In this presentation NewtonWorks’ latest method to integrate structural FE models and physical modeling method.
