摘　　要：提出一种新型的三角肘杆式伺服压力机传动机构。运用MSC.ADAMS建立三角肘杆机构的虚拟样机,进行运动学仿真并按设计需求进行性能优化。在建立的虚拟样机模型中,考虑实际工况中的多种影响因素,引入滑块和模具重力、板材成形力、平衡缸作用力等综合分析计算,使优化设计后的三角肘杆机构在满足滑块快速合模、下死点保压和快速回程等工艺需要的条件下,有效降低电机功率,降低能耗。A new kind of triangle toggle rod transmission mechanism for servo press has been put forward in the text.The virtual prototype of the mechanism has been established by use of MSC.ADAMS software.The optimization and simulation of kinematics and dynamics have been carried out according to the design requirements.Lots of influencing factors,weight of slide and die,sheet forming force and balance cylinder force,have been considered in the virtual prototype.In this way,the triangle toggle rod transmission mechanism can meet the demands of high die speed,pressure-maintaining in bottom dead center and high back haul speed through the optimized design. Besides,the need about the power of motor has been reduced which saves the energy.
