登錄ansys apdl 導出mnf文件到adams里后,零件的模態頻率和ansys里的不一致,求大佬指點


請問一下各位大佬,為什么隨機振動得到的響應psd曲線和輸入的psd載荷譜一樣啊?


Element 47 (corresponding to layer 2) has a mesh thickness of 0.745 that is not consistent with the other elements (thickness=0.76356052). The mesh must have the same thickness for each layer.

其次,就是提取節點加速度的,直接提取加速度和采用求導位移的出入有點大,能否一致?
