摘　　要：针对考虑运动副间隙三角连杆肘杆式压力机机构动力学建模、仿真及分析问题,提出了相应的向量键合图法。基于无质量杆-弹簧阻尼运动副间隙模型,建立了含运动副间隙的三角连杆肘杆式压力机机构向量键合图模型。应用相应的方法,使机构向量键合图模型的贮能元件皆具有积分因果关系。在此基础上,基于Matlab实现了含运动副间隙三角连杆肘杆式压力机机构计算机建模及动力学仿真,分析了运动副间隙对压力机机构运动学及动力学性能的影响,验证了所述方法的可靠性及有效性。For the dynamics modeling,simulation and analysis of a triangular connecting rod toggle press mechanism with considering the kinematic pair clearance,the corresponding vector bond graph procedure is proposed.Based on the kinematic pair clearance model of massless-link/spring damper,the vector bond graph model of a triangular connecting rod toggle press mechanism with kinematic pair clearance is built.By the corresponding method,all the energy storage elements of the mechanism vector bond graph possessed integral causality.Based on these,the computer modeling and dynamics simulation of a triangular connecting rod toggle press mechanism with kinematic pair clearance is realized by Matlab,the influences of kinematic pair clearance on the press mechanism kinematics and dynamics performance are analyzed,and the reliability and validity of the procedure proposed are illustrated.
