摘　　要：对目前普遍使用的三分力气囊检测装置建立了动态模型并进行仿真。结果表明:当阻尼比为0.6,固有频率和阻尼比的相对变化量皆为1%时,模型相对误差可达4.5%以上。该模型误差不容忽略,但采用峰值叠加和增大检测装置阻尼比的措施可减小此误差。A dynamic model for three component-force airbag detection device commonly used at present is built and a simulation is conducted.The results show that when damping ratio is 0.6 and the relative variations of both natural frequency and damping ratio reach 1%,the relative error of model can be more than 4.5%,which allow of no neglect,but can be reduced by force peak superimposition and increasing the damping ratio of airbag detection device.
