摘要
以包装件的力学模型为依据 ,用脉冲响应法求解产品中易损零件对振动环境的响应。侧重于求解 ,即已知振动环境的统计特性 ,求解零件响应的平均值、均方值、幅值概率密度函数 ,自相关函数和功率谱密度函数 ,导出了这些统计参数和统计函数的计算公式。
Basis on the dynamics model of the product package system,the response of vibration environment in fragility part of this system is calculated with the method of pulse response.According to the statistic character of the vibration environment.The arerage value, mean-square-value,Amplitude probability densitig function,self-relevent function and power spectrum density function is calcutated,the equation of the statistic parameter and statistic function is given.
