【摘要】 可倾瓦轴承的瓦块变形问题相对瓦块摆动问题一般认为是次要问题,但在重载和高速等超常情况下,这个问题可能变成主要问题或难点。本文用理论和数值方法讨论变形的现象和特征,进而提出分析瓦块变形问题的简要方法。论文内容包括瓦块两类变形的仿真数据及宏微现象、表征瓦块变形的参数集、表征瓦块变形的典型参数获取途径、与瓦块变形相关的安全评定手段及瓦块变形问题的设计规则以及典型案例等。以上内容构成了一个简要方法及对其相关说明。更多还原

【Abstract】 Comparing with the problem on pad swing,the problem on pad deformation of tilting pad bearing is usually considered as the secondary problem,but in the extraordinary condition of heavy duty and high-speed,this problem could become major problem or difficulty.The phenomenon and the characteristics of deformation were discussed with theory and numerical methods in this paper,and then a brief method to analysis problem on pad deformation was proposed.The contents include simulation data and macro and micro phenomena of two kinds deformation of pad,parameter set representing pad deformation,ways of obtaining the typical parameters that represent pad deformation,safety evaluation methods related to pad deformation,design rules of problem on pad deformation and typical cases,etc.The above contents form a brief method and related instructions.更多还原
