摘要
建立八连杆压力机传动机构的ADAMS模型,利用Newton-Raphson迭代法解出压力机的性能曲线.根据生产和性能要求,采用OPTDES-SQP二次规划算法优化滑块的加速度曲线.根据优化结果建立三维模型,运用workbench验证传动机构的强度要求.该结果为八连杆压力机传动机构的设计优化提供了理论依据.
The eight-link model in ADAMS is established, the performance curve of mechanical press is obtained by Newton-Raphson iteration method. According to the production and perform- ance requirements, the slider acceleration based on OPTDES- SQP method is optimized. This paper establishes 3D model of transmission mechanism and verifies the strength in workbench. The re- suits provide a theoretical basis for structure design of transmission mechanism.
