Problems solved by technology

The disadvantage is that the traditional displacement and stress are still used as the conditions for judging the strength of vibration, and there is no concept of vibration energy.

The disadvantage of this method is still the lack of analysis from the perspective of energy, and the simple stress and displacement cannot provide all the information of the vibration characteristics.

Another scholar provides an analytical method, which is characterized by analyzing the transient response through the dynamic equation of the rotor, but the disadvantage is that the method has large limitations and a large amount of calculation is difficult to solve
