| Abstract: | By considering the construction and material property of a wobble plate engine, the concentrated parameter models of multi-DOF freedoms are built up for vibration of low frequency in axle and spin directions. The distributed parameter model equivalent to transmission matrix analysis is employed for higher frequency vibration, supposing that the wave impedances of two components determine the vibration transmission through their interface. Exciting forces in the example engine are analyzed and applied to vibration spectrum computation. The predicted vibration spectrum agrees well with the test data in tendency. |
