基于多体系统传递矩阵法的多层皮革裁床转子机构的动力学模型

针对多层皮革裁床在高转速下振动噪声大的问题,应用多体系统传递矩阵法,对分叉和闭环混合多刚柔体系统建立了动力学模型.在建立裁床总体传递矩阵的过程中,提取出对裁床振动影响最大的机构,并采用集中质量参数法简化为弹簧阻尼结构,通过分析找出了3条振动传递链,同时结合传递链的边界条件,用Matlab软件求解得到了多层皮革裁剪机刀头...

Dynamic Model of Multi-layer Leather Cutting Machine Based on Transfer Matrix Method of Multi-body System

To provide the solution to large noise and vibration caused by the multi-layer leather cutting machine at high speed,the transfer matrix method of multi-body system is employed to build a dynamic model of the bifurcate and closed system.In the process of building a transfer matrix of the cutting machine,a mechanism having the maximum effect on the machine vibration is picked up and simplified into a spring-damping system.Based on the analysis,three vibration transfer chains are found.Combined with the bound...
