MODEL DESCRIPTION
The solid finite element model of the knuckle has been built using a second order solid tetrahedron element. The model has 27,832elementand 47,291 nodes. The loads are applied at the upper, lower and tierod ball joints. The loads are applied using dummy springs and displacements. We have three dummy springs (representing each of the three directions) at each of the knuckle vertical load points. One end of the springs is attached to the knuckle while the other end is free to move only in one direction. A specified displacement is given at that end to generate a suitable load. A preliminary NASTRAN stress analysis of the FE model took about 00:24:01 hours on a Power Challenge SGI system. The Ⅰorder FE model of the knuckle had only 7,265nodes and it took only00:05:22hours for a baseline run.
Shape vectors, which are the most important inputs for shape optimization, were generated using‘Autodv’. The method is as follows. A group of elements are first identified

模型说明
这一坚固的转向节模型是由坚固的二级四面体单体元素做成的。模型包括27，832个单体元素和47，291个节点。受力点分布在上部、下部和拉杆的球形连接点上。作用力来自于弹簧模型和移位。我们在每一个转向节的垂直受力方向设置了三个弹簧模型，（分别代表三个不同的方向）。弹簧的一端和转向节相连而另一端可以在一个方向上自由移动。如果给弹簧的末端施以指定的移动使其受力，根据应力学基本软件的力学分析 FE 模型就会有大约00:24:01小时的动力产生来挑战 SGI 系统。一序列 FE 型的转向节只有7，265个节点，它的基准线运动只需要00:05:22小时。
使用模型，是优化机构的重要方法，这样的模型被叫做 Autodv。这种方法如示。一组基本元件得到了首先确认。
