摘要
给出了一个在振动系统中放置磁流变阻尼器的有效方法.利用虚拟阻尼器,放在结构感兴趣的位置,可以计算出虚拟阻尼器所消耗的功率值,根据虚拟阻尼器在振动系统中不同点所消耗的功率数值,讨论了寻找放置阻尼器最佳位置的方法.为了说明这种方法的有效性,用Newmark方法进行数值积分,求得节点的响应,计算了含有MR(magneorheological fluid)阻尼器的车架结构,结果说明所提供的方法和寻找准则是正确的和有效的.
An effective procedure for determining the locations of the MR dampers in vibration systems was developed. Using the virtual damper placed at the system of interest locations, the energy dissipations of the virtual dampers can be computed. According to the values of energy dissipations of virtual MR dampers placed at different positions, the search procedure for the best locations of MR dampers is discussed. In order to illustrate the control effect of MR dampers on vibrations of structures, the nonlinear response analysis is also discussed with Newmark method. Using the present methods, a numerical example of an automotive chassis is given in this paper. The results obtained in the numerical example indicate that the present procedure is valid and effective.
