Efficient Modal Analysis of Prestressed Structures via Model Order Reduction

Solid Modeling and Finite Element Analysis of Diaphragm Spring Clutch

“…Modal is the natural vibration characteristic of a mechanical structure, and each rank of modal has its special natural frequency, damping ratio and modal shape. Diaphragm spring is the most key component for automobile clutch, and working performances of clutch are all closely related to the diaphragm spring, such as engaging force and travel distance of pressure plate, driving force of pedal, and travel distance of releasing bearing [8]. Moreover, when diaphragm spring is undertaken outside impulsion and vibration force, there will be notable affection on the performance of clutch.…”
