Random Vibration Spectrum Analysis Based on Finite Element Method of High-Pressure Cylindrical Cylinders

In order to solve the vibration problems of car high-pressure cylindrical cylinders, Plate and Shell Vibration Theory is used for the calculation and analysis of the vibration characteristics. The vibration frequencies and modes of such cylinders are obtained. At the same time, the corresponding results are gotten through ANSYS12.0 simulation calculation. The similarities and differences of the both vibration frequencies and the changes of the respective modes are compared and analyzed to support the farther safety performance analysis of such cylinders in the vibration environment.
