| 摘 要： | 针对铁路重载货车疲劳设计的被动局面,基于美国ARR标准,以数学手段提出了结构设计反求技术.不同于传统的静强度下的应力设计,它是根据疲劳寿命要求反求出以动载荷标定的设计应力,从而实现了真正意义上的寿命设计.取ARR标准中一个典型案例进行设计反求,证明了所提出反求设计的数学模型是可靠的.

| Abstract: | In order to change the passive situation of fatigue design of heavy railway rolling stocks, a new technology named reversing design is presented by means of mathematics based on the fatigue design standard-AAR. This method, different from the traditional one based on the allowed stress, a true life design and able to obtain the stress according to the need of fatigue life. One typical example taking from AAR proves that this mathematical model is reliable. |
