sc0 ls0 ws0">的仿真软件，<span class="_ _7"></span>它集合了先进的有限元分析、<span class="_ _7"></span>流场分析等，<span class="_ _7"></span>而我们的焦点在于它的动力学仿真</div><div class="t m0 x1 h2 ya ff1 fs0 fc0 sc0 ls0

WORKBENCH<span class="_ _0"> </span></span>进行模拟时，<span class="_ _3"></span>首要步骤就是将我们的目标对象<span class="ff2">——</span></div><div class="t m0 x1 h2 yd ff1 fs0 fc0 sc0 ls0 ws0">这里即是一个轴承模型进行构建。<span class="_ _7"></span>这里的轴承模型包括内圈、<span class="_ _7"></span>外圈以及滚子等部分。<span class="_ _7"></span>我们需</div><div class="t m0 x1 h2 ye ff1 fs0 fc0 sc0 ls0 ws0">要对每个部分进行细致的建模和参数设置，<span class="_
