| 摘 要： | 齿轮齿条的强度是关系整个平台安全性能的一个重要因素,对其进行强度校核非常必要,而对齿轮齿条进行强度分析的关键问题就是确定施加在齿轮齿条上的载荷。通过建立平台整体有限元模型,分析平台爬升齿轮齿条所受载荷,将上述载荷施加在有缺陷的齿轮齿条模型上,计算出齿轮齿条的极限磨蚀或腐蚀量,并将此极限磨蚀或腐蚀量作为判断目标平台齿轮齿条失效的标准。

| Abstract: | Since the strength of rack and pinion is an important factor for the safety of the whole platform, strength verification becomes necessary. The load on the rack and pinion is critical for the strength analysis. The finite element model of the whole platform is built to analyze the load on the climbing rack and pinion in the platform. These loads are applied on the model of rack and pinion with defects to calculate the ultimate abrasion and corrosion, which can be taken as the criterion for failure judgment for rack and pinion. |
