（转子动力学模态分析）求助
这是我做的多级泵转子模态分析在最后用PLCAMP命令绘制 坎贝尔图的时候 总是提示下列警告：
我分析是的命令流如下：

ansys 转子动力学 求助
转子动力学 ansys 模态分析 求助附件为警告 其实就是个静态求解的问题，将模型简化成平面问题，施加轴向速度、轴向约束，即可求解。上面有人提到用动力方法求解，动力方法的前提应该是变加速，本题显然是稳定的速度，而且加速度为零。 你能够确信ＡＮＳＹＳ 软件计算的结果吗？ qijunshuai 发表于 2007-9-15 11:14 static/image/common/back.gif
你具体做什么？ 期待交流！！呵呵。;qq:474525152
你的问题解决了吗，我现在也正困惑于此，希望能得到你的帮助，谢谢！
