Optimal Design of Bracket Isolator Stiffness in Vibration and Shock Environment

  • 摘要: 文章在某型号的电子设备支架减振器设计中,综合考虑了振动、冲击两种主要的力学环境。以减振器刚度为设计变量,将刚度的倒数作为目标函数,根据振动、冲击环境设计要求确定了约束条件,建立了减振器刚度优化的数学模型。采用ANSYS作为优化设计的平台,随机振动响应分析采用振型叠加法,冲击响应分析采用Newmark时间积分法,对该问题进行了优化求解,取得了满意的结果,为电子学系统的减振设计提供了依据。
    Abstract: In this paper, the bracket of a electric equipment is designed by considering the vibration and shock environment. According to the design requirement with respect to vibration and shock, the stiffness of the isolator is used as the design variable. The mathematical optimal model for searching the largest stiffness of isolator is built to make the relative displacement small. The optimal problem is solved using ANSYS. Both the mode superposition method and the Newmark integrating method are used to obtain the response of stochastic vibration and shock. The optimal results could be used in the isolator design of the electric system.
