Slipper type universal coupling"s fork joint and palm end are the weak parts of the main transmission system. In this article, the two parts" intensity values are obtained through finite element analysis . After making three-dimensional computer simulation analysis by ANSYS, the results show that the middle arc of the fork joint in loaded side and the intersection of fork bore and the arc are the danger location, where the stress is largest and stress concentration is serious.

本文对轧机主传动系统机械部分的薄弱部件进行强度计算，即对滑块式万向联轴器的主要零部件的强度进行有限元分析，通过ANSYS有限元分析软件进行三维计算机仿真，由计算结果可知，在叉头受载侧过渡圆弧段中部、叉头镗孔与过渡圆弧交接处这两个部位的应力最大且存在严重的应力集中，考虑到单元总数限制及计算时间等因素，整体模型的网格划分较疏，不能反映倒圆角等细节。

The expression of performance requires some united systematic variations from the score, so this trend of exactness, evenness has gradually restricted the artistic creation. From the aspect of tradition, most of the performance conventions such as tempo flexibility, independence of melody and accompaniment, tenuto and agogic accent, over-dot, under-dot, notes in gales and unwritten arpeggiation etc. have a long history and they are usually part of the composer ' s expectation.

由于音乐表演的表现力因素必然要求演奏相对于乐谱有一定偏离，因此这种精确化、规整化的趋势从科学角度来看实际上是逐渐限制了艺术创造的基本空间；而从传统角度来看，诸如速度弹性、&旋律自由而伴奏保持严格速度&的声部错位、时值缓急重音、过符点、欠符点、不平均音符、和弦的琶音处理等演奏惯例大都具有久远的历史，时常是创作阶段完整艺术构思的一部分。
