摘　　要：建立了斜支承弹簧减振系统的竖向非线性振动控制方程,研究了斜支承弹簧减振系统的竖向非线性自振问题。采用L-P法推导了斜支承弹簧减振系统竖向非线性自振的近似解,讨论分析了斜支承弹簧的倾角、减振系统的竖向振幅等因素对斜支承减振系统非线性自振的影响,为斜支承弹簧减振器的设计提供了理论依据。The governing equation of vertical nonlinear vibration was founded for shock absorber system with tilted support spring, and its vibration behavior was studied. Based on L-P method, the approximately solution of the equation was provided and the effects of oblique angle of tilted support spring , vertical amplitude of shock absorber system, etc.on the nonlinear natural vibration were discussed. The proposed method provides academic foundation for design of shock absorber with tilted support spring.
