剑杆机冲击隔振器参数优化设计

针对机械设备受周期冲击干扰的积极隔振问题,提出了冲击隔振参数优化设计的新方法。通过对隔振系统的机械阻抗分析,提出由试验分析识别复杂设备干扰力源的方法,为各类隔振工程设计问题提供了简捷、有效的途径。计算机仿真结果证明了上述设计思想和试验方法的正确性和可行性。文末给出了这种方法成功地应用于大面积剑杆式织机上楼的冲击隔振的实例。

Optimum Design of Impact Isolator for Rapier Looms

For the problem of the active vibration isolation of machines with periodic impact disturb, a new idea is presented for the optimum designing of impact isolator parameters. It is proved that the complex disturb sources in mechanical devices can be identified with simple experiment, and a forthright way is suggested for solving the problems of vibration isolating. The method is verified by computer simulation, and used to solve a practical problem of vibration successfully for a factory, in which 40 rapier looms are mounted on the second floor.
