摘要
针对物流产品在运输过程中的状态以及如何预估产品疲劳寿命的问题,根据当前的损伤评价标准和经典损伤理论,列举出两种常见疲劳寿命预估方法。通过实例从理论分析和Matlab Simulink数值仿真分析两个方面验证了两种方法的有效性,而且两种方法预估的产品疲劳寿命基本一致。通过对产品的疲劳寿命的预估,可为产品的运输方式、运输时间选择以及运输缓冲包装设计提供参考。
Aiming at the conditions of logistics products in the process of transportation and the issues of estimating the fatigue life of the products,two common fatigue life prediction methods were listed according to the current damage evaluation criteria and classical damage theory.The effectiveness of the two methods was verified by examples from theoretical analysis and Matlab Simulink numerical simulation analysis,and the predicted fatigue life from the two methods was basically the same.By estimating the fatigue life of the product,it could provide reference for the transportation mode,transportation timing and transportation buffer packaging design of the product.
