| 摘 要： | 本文利用传递矩阵法对Watt型平面六连杆机构的固有频率进行计算.推导了该类机构横向振动的传递矩阵,算出了它的低价固有频率,利用7T17-S频谱分析仪进行试验模态分析,得到了相应结果.这种分析方法在数值求解时只需计算低价次的传递矩阵和行列式值,因而可在PC机上进行.它也适用于其它型式连杆机构的振动分析.

| Abstract: | The lower-order natural frequencies of the Watt type of the planar six-bar linkage are calculated by transfer matrix in this paper. The transfer matrix of transverse vibration of this mechanism is conducted and its lower-order natural frequencies are calculated. The experiment of the modal analysis is done with Signal Processor 7T17-S and the experimental results are the same as the calculated ones. This analysis method with numerical calculating only requires calculation of lower-order transfer matrix, so that, it can be made with microcomputer such as IBM-PC. The methods adopted in this paper are also suitable for vibration analysis of other linkage. |
