主动式磁流变液阻尼动力吸振器的优化设计

The optimum design of active vibrat ion absorbers of the magnetic rheology damp

通过理论研究建立主质量和动力吸振器组成的力学模型及大量的数值计算,用优化设计的方法获得最佳吸振效果的吸振器的安装位置和质量、阻尼系数和刚度系数的变化范围.利用有限元分析软件ANSYS求得系统受随机激励时的结构响应和频率分量,建立主动式动力吸振器的设计理论和方法.

This paper sets up the mechanical model of the main mass and dynamical vibration absorbers by the academic research and much numerical calculation, and gets the optimal installation position and mass of the vibration absorbers, the range of damp coefficient and rigid coefficient by the method of optimum design. Having got the structural vibration response and frequency component applied in the random vibration system with FEM software ANSYS, and the paper sets up the design theory and method of the active dynamical vibration damp.
