摘　　要：为了正确确定特种产品定加速运输振动模拟试验的条件,利用概率论与数理统计的方法,在线性疲劳累积损伤假设的基础上,以相同的结构疲劳损伤作为加速模拟的等效准则,确定了特种产品加速模拟振动试验所要求的振动量值和试验时间.通过在不运输、跑车试验和加速模拟振动的对比试验证明,将提高振动量值、缩短试验时间的加速试验方法应用于特种产品加速运输模拟试验是切实可行的,它可以节约人力、物力和财力,提高试验效率,也可以作为特种产品或包装箱设计及考核的标准.To determine correctly the accelerated transportation vibration experiment conditions of special products, the vibration intensity and lasting time of the simulated vibration are evaluated with the fatigue damage equivalent principle based on the probability theory, mathematical statistical methods and the theory of linear accumulated fatigue damage. A set of comparative experiments including lack of transportation, real road transportation and vibrator are conducted for a type of special products. The results show that the strategy,i, e. , increasing the vibration intensity and shortening the lasting time of the simulated vibration, is feasible to apply to accelerated transportation simulation experiment to save manpower, material resource, financial resource and improve the experiments efficiency, and provide a criterion to design and examine the special products and packing case.
