摘要: 减振器是汽车悬挂系统的重要结构件，主要作为承受车辆本身的重量和颠簸时的缓冲器，振动破坏是减振器的主要损坏形式。对减振器进行静力学分析、模态分析和谐响应分析，找出振幅较大的区域，以避免发生共振，在模态分析的结果上，进行谐响应分析，得到减振器的应力–频率响应曲线和相位图，确定了发生共振频率及区域。分析结果表明，减振器的轴心与轴端区域易发生振动破坏，为减振器的设计和优化提供了参考。
Abstract: Shock absorbers, critical components of a car’s suspension system, primarily bear the vehicle’s weight and dampen shock during bumps. Vibration damage is the predominant mode of shock absorber failure. Through static, modal, and harmonic response analysis of shock absorbers, this study identified high amplitude regions to evade resonance. Based on modal analysis outcomes, harmonic response analysis was carried out, yielding the stress-frequency response curve and phase diagram of the shock absorber. Resonance frequencies and zones were pinpointed. Analysis revealed that the x-axis and shaft end regions of the shock absorber are prone to vibration failure, providing references for the design and optimization of shock absorbers.
