摘要
研究具有直线与摇摆耦合运动的振动传递路径系统的传递特性,用路径传递率对各路径的贡献度进行评价,找出主要路径。通过计算接受体能量对主要路径参数的灵敏度,确定出系统的主要参数。当系统路径参数较多时,该方法能合理地选择设计参数,大大简化振动传递路径系统的优化设计过程。通过算例表明,所述的分析方法切实可行,为时域内振动传递路径系统的参数贡献度分析提供新的有效途径。
The transmission characteristics of multi-degree-of-freedom vibration transfer path systems with the motion composed by straight-line translation and rotation were studied. Contributions of the paths were evaluated with path transfer ratio. And the main transfer path was determined. Based on the sensitivity analysis technique, the parameter sensitivities of the main path to the receiver energy were analyzed, and some important path parameters were determined. This method can be conveniently used to select the appropriate design parameters, and the design process can be greatly simplified, The numerical example shows that the proposed method is feasible and effective for the parameter contribution analysis of the vibration transfer path systems in time domain.
