Numerical Simulation and Dynamic Optimization of Power Characteristics of Vibration Damper
In order to solve the problem that the vibration damper cannot give full play to the best anti-vibration property under different working conditions,the author constructs the model of the vibration damper subsystem,simplifies the power characteristic data acquisition equation,designs the experimental device was to numerically simulate the power characteristics of the vibration damper,through whith the power characteristic curve of the vibration damper is obtained,and uses the Kriging model is used to dynamically optimize the bending stiffness of the strand,the friction coefficient between strands and the internal damping of the vibration damper.The experimental results show that the simulation results are close to the measured results,and the simulated values of the power characteristics of the vibration damper are reliable.Under different frequency conditions,the amplitude and amplitude ratio of the transmission line is smaller after optimization,which shows that the vibration damper has higher power consumption and better anti-vibration property.
