Optimal Design of Bracket Isolator Stiffness in Vibration and Shock Environment

In this paper, the bracket of certain electric equipment was designed by considering the vibration and shock environment. According to the design requirement of vibration and shock, the stiffness of the isolator was set as the design variable. The mathematic optimal model of getting the largest stiffness of isolator was built to make the relative displacement smaller. The optimal question was solved by using the ANSYS. Both the mode superposition method and the Newmark integrating method were used to get the response of stochastic vibration and chock. The optimal result provided gist for the isolator design of the electric system.
