1. It is necessary to establish an accurate model, including the geometric shape of the structure, the physical characteristics of materials, boundary conditions, etc.
2. The model is divided into many small units, and the vibration equation of each unit can be expressed by mathematical formula.
3. By calculating the vibration equation of each element, the vibration state of the whole structure can be obtained.
4. According to the obtained vibration state, we can analyze the dynamic response of the structure, such as displacement, velocity and acceleration.
