摘　　要：为了提高压力机构运动的稳定性,改善冲压件产品质量。采用改进蚁群算法优化目标函数,得出八杆压力机构设计参数。采用数学软件MATLAB对八杆压力机构的滑块速度进行仿真,输出滑块运动速度曲线。结果表明:在冲压行程内,优化后的八杆压力机构滑块速度运动平稳,回程速度较快。采用改进蚁群算法优化八杆压力机构,能够提高汽车薄壁冲压件产品性能。The pressure mechanism was unstable in the stamping stroke,causing the quality of the stamping parts to drop.In this regard,the improved ant colony algorithm was used to optimize the objective function,and the design parameters of the eight bar pressure mechanism were obtained.The slide speed of the eight bar pressure mechanism was simulated by using the mathematical software MATLAB,and the speed curve of the slider was output.The results showed that in the stamping stroke,the optimized eight bar pressure mechanism slider had a steady speed and a fast return speed.The improved ant colony algorithm wasused to optimize the eight bar pressure mechanism to improve the processing quality of stamping parts.
