摘　　要：为了提高产品设计质量,降低成本,缩短研发周期,在印刷机设计过程中采用了虚拟样机技术对三点支撑式离合压机构进行了研究。通过建立三维数字化建模、机构装拆仿真、调整模拟、运动仿真,对机构的物理、力学性能进行分析、模拟、预测,对关键零件进行受力分析并给出了应力-应变图,对关键机构的关键运动点给出了位移、速度、加速度曲线,实现了设计方案的快速实施。结果表明:在由凸轮驱动的离合压机构中,随着印刷速度的增大,离合压机构在工作过程中易产生冲击与振动。因此,提高凸轮的加工精度,可减少印刷过程中产生的振动与冲击,提高印刷质量。In order to improve the quality of product design, reduce the cost, shorten the development cycle, virtual prototyping technology is used in the process of three points support type clutch press mechanism. The design scheme is rapidly implemented through establishing three-dimensional modeling, assembly and disassembly, adjustment mechanism simulation, motion simulation of mechanism. The physical, mechanical performance of mechanism is analysed, simulated, and predicted. Stress analysis of key parts gives the stressstrain diagram, the key institutions of moving point give dis- placement, velocity and acceleration curves. Through the virtual operation simulation, early detection of defects can realize the optimization design.
