两种阻尼模态方法的说明：
Damped method
The damped method is used for problems where damping cannot be ignored, such as bearing problems.
QR Damped method
The QR damped method is faster and achieves better calculation efficiency than the damped method. It uses the reduced modal damped matrix to calculate complex damped frequencies in modal coordinates.
包括了阻尼不一定结果就不一样了，要看阻尼的设置了
包括了阻尼后结果没有计算出来，第一要看你去掉阻尼后能计算出频率吗？然后还有阻尼计算是要设置正确！
