罗拉刚度的可靠性研究

Reliability analysis of winding rigid on the roller

罗拉是纺织机械上的一个重要零件,其主要功能是牵引和喂入棉条,长径比16～22左右, 属于细长轴,要求具有足够的弯曲刚度。采用概率法计算,将载荷、尺寸、材料性能等参数视为随机变量,运用蒙特卡洛(Monte carlo)模拟法对罗拉弯曲刚度进行可靠性研究。

By the method of probability and taking the parameters such as load, size and material characteristics as random variables, the reliability of winding rigid of the roller is analyzed by the way of Monte-carlo random sampling.
