摘　　要：为保证侧碰传感器安装位置的动刚度及共振性能,提出侧碰传感器安装位置结构动刚度及共振性能评价的频率响应分析方法。以某车型安全气囊侧碰传感器安装位置结构为研究对象,利用Hyper Mesh软件建立了有限元模型,通过Radioss求解器进行了动刚度及共振性计算分析,然后对安装位置结构进行了改进设计。最终优化方案达到了设计目标要求,避免了侧碰安全气囊在车辆正常行驶过程中发生误爆等危害乘客安全的隐患。In order to guarantee a certain dynamic stiffness and resonance performance for the installation position of side impact sensor,with frequency response analysis method,the evaluation standard of dynamic stiffness and the resonance performance was established for the installing position of sensors with side impact. The finite element model for analysis was established by Hyper Mesh software,and calculated by Radioss solution. Curves of calculated results were analyzed,and the structure of the sensor installing position optimized made the dynamic stiffness values and resonance performance of sensor installing position met practical requirements.
