碟形弹簧的非线性自由振动

On the Nonlinear Free Vibration of Disk Spring

研究了碟形弹簧的非线性自由振动,建立了碟形弹簧非线性自由振动的控制方程,采用L-P法推导出了碟形弹簧非线性自由振动的固有频率近似公式,讨论分析了碟形弹簧的振幅、重物质量对其固有频率的影响,为碟形弹簧的设计提供了理论依据。

The nonlinear free vibration of disk spring was studied.And its governing equation was presented,and then the formula for its inherent frequency was deduced by L-P method.At the same time,factors that affected the natural frequency such as vibration displacement and mass's weight were discussed.The study provides basic information for design of disk spring.
