Vibration visualization of finite element power flow for fully flexible vibration isolation system
In order to fully consider the influence of the foundation and machine flexibility of large vibration isolation systems such as ships,the mass and layout of isolators on vibration transmission,and to overcome the issue that traditional methods were not suitable for modeling and analyzing large flexible structures.A new fully flexible isolation system was built,in which the machine and the foundation were regarded as flexible irregular shaped plates,and the space beam was used to model the vibration isolator,respectively.The finite element method was introduced into the vibration calculation of the vibration isolation system to avoid the complex process of calculating the mobilities of the machine and the foundation,and the expression of the transmitted power flow of the flexible vibration isolation system was given.Through visualizing the vibration transmission of the system,the energy distribution and power flow transmission of the structure were obtained.It could be used for reference in the prediction of vibration transmission and vibration isolation design of mechanical equipment.
