擦窗机研发速度逐渐加快,需建立科学的设计和改造方法。本文根据折臂式擦窗机的工作原理,推导出底座和立柱受力随工况参数变化的显式表达式,确定其危险工况;在危险工况下,对底座和立柱进行有限元分析,找出了应力分布规律,为底座和立柱的设计提供了有价值的参考。 Grab window research and development speed gradually accelerated, the need to establish a scientific design and transformation methods. Based on the working principle of the arm-type gondola machine, this paper deduces the explicit expressions of the force variation of the base and the column with the working parameters, and determines the dangerous conditions. Under dangerous conditions, the finite element analysis of the base and the column , Find out the law of stress distribution, and provide valuable reference for the design of base and column.
