轴瓦材料的特殊性使弹性金属塑料瓦(EMP)径向滑动轴承的热弹变形远大于普通金属瓦轴承，本文着重分析其弹性变形对轴承润滑特性的影响。并对采用三维有限元法和Winkler假设方法计算得出的轴瓦弹性变形进行了比较。给出了EMP径向滑动轴承弹性变形分析研究的一个实例，对其润滑特性进行了初步分析。“,”Since special properties of synthetic material uses in pad of the EMP journal bearing, the elastic deformation and thenno-deformation rnwill be larger than that of traditional bearing with metal pad. This paper puts the emphasis on the elastic deformation. Compares the result obtained by using the finite element method with that obtained by using Winkler assumption. At last, an example is given to prove the lubrication per formance of EMP journal bearing.
