多连杆机构运动分析及其系统的应用161005齐齐哈尔第二机床厂王海峰候玉红由于多连杆机构的构件多,各杆之间的连接也复杂,因此,采用何种方式建立正确的数学模型尤为重要。笔者经过分析和探讨,采用了“矢量微分法”。下面,以德国埃尔富特公司的十杆机构(图1)...
Multi-link mechanism motion analysis and system application 161005 Qiqihar Second Machine Tool Plant Wang Haifeng Yu-Hong Wang Multi-link mechanism due to the many components, the connection between the rod is also complex, so the way to establish the correct mathematical model Particularly important. After analysis and discussion, I used the “vector differential method.” Below, to ten companies in Germany Erfurt’s body (Figure 1) ...
