As one of the most potential experimental stress measurement , ultrasonic technique was widely developed and applied in recent years . limited by their own characters , bulk wave and surface wave in ultrasonic frequency are difficult to be used to measure the internal tangent stress condition from the surface of medium . in many occasions , they will not be able to evaluate the working condition of mechanical components effectively 超声波技术作为最有潜力的实验应力测量技术之一,近年来得到了广泛的发展和应用,然而超声体波与表面波由于其自身的限制性,均无法从表面测量内部的切向应力状况,在许多场合下无法有效进行机械构件工作状态的评估。
So it is necessary to research an adaptive design method for the disposable machine . in this thesis , compared with the conventional machine , the characters and the applied ranges of the disposable machine have been analyzed and concluded , and the leading idea of the design method of the disposable machine has been determined 在本文中,通过与常规机械的对比,分析归纳了一次性机械的特点及其应用范围,确定了其设计方法的主导思想,即在设计过程中不考虑疲劳和磨损,按照静强度要求对机械构件进行设计计算。
