在此基础上应用ANSYS软件对无圆角、单圆角、双圆角矩形和梯形四种截面的螺杆进行了三维应力分析。

Under the condition of knowing trolly"s relation datas, the wire rop-load modle taking its load as the study object, using D"Alembert"s Principle and Hybrid method, solves out the mathematical expression of wire rop"s traction while settig the hiost speed; The elctronic motor-drum modle"s build up is attracted to the elctronic motor"s torque, and combines with the wire rop traction"s role on drum, only pay attation to the coupling"s flexibility and damping, which is between the elctronic motor and the reducer. The theory of transmission equations establishment is in Project Vibration.

钢丝绳—吊重模型是在小车运行机构的相关数据均已知的情况下，以吊重为研究对象，利用达朗伯原理和动静法，在假定起升速度已知后求解出钢丝绳牵引力的表达式；电动机到卷筒部分的模型则是建立在电动机输入转矩形式已知的基础上，结合钢丝绳牵引力作用在卷筒上的工作阻力矩，只考虑电动机与减速箱之间的联轴器的弹性阻尼，利用工程振动原理建立传动方程。

It is widely employed in many industrial domains. The most attractive domain of ring rolling technology is to roll the rings with specially-shaped cross section directly. But the rolling deformation law of ring with specially-shaped cross section is more complicated compared with rectangle section ring and in the process there are lots of special phenomenon such as underfilling, shrinking-drawing, concave, saucer shape and etc.

环件轧制技术最有吸引力的领域和发展方向是直接轧制成形截面轮廓复杂的异形截面环件，然而，与矩形截面环件相比，异形截面环件轧制成形规律更复杂，轧制过程中常常出现截面轮廓充不满、拉缩、凹坑、碟形等各种特有现象，这些现象是异形截面环件轧制成形规律的客观反映。

The calculation results of some examples are given. In the unstratified case, the cake cross section at any point is circular. When the flow is stratified, buoyancy cause the wake, which initially grows at the same rate in all directions, to collapse in the vertical direction and flatten out horizontally producing a very wide and thin rectangular shape.

在稳定层化海洋中，潜艇尾流以圆锥形增长；在非层化海洋中，初期尾流也以圆锥形增长，但在浮力作用下，尾流垂向增长崩溃，然后以又薄又宽的近于矩形截面增长，最后垂向尺度趋于常值。
