摘要 传统的圆柱螺旋压缩弹簧设计多采用试凑法,设计效果因人而异,一般不能得到最佳设计参数,且耗时费力;而针对弹簧某一特定要求进行参数优化的单目标优化设计方法,其优化目标单一,也不能获得最优综合性能指标。在分析研究圆柱螺旋压缩弹簧优化设计存在多目标、多约束特点的基础上,建立了基于弹簧结构质量和自由高度最小及自振频率最高的多目标优化设计模型,并应用MATLAB软件进行优化计算。优化结果表明,多目标优化设计可以有效解决圆柱螺旋压缩弹簧的设计问题,使其各项参数指标更加均衡,更加契合弹簧实际工况和满足工作要求。 The traditional design of cylindrical helical compression spring mostly adopts trial and error method, and the design effect varies from person to person. Generally, the best design parameters can not be obtained, and it is time-consuming and laborious;The single objective optimization design method optimized for a specific requirement has a single optimization objective and can not obtain the optimal comprehensive performance index. According to the characteristics of multi-objective and multi constraint in the optimization design of cylindrical helical compression spring, a multi-objective optimization design model based on the minimum spring structural mass and free height and the highest natural vibration frequency is established, and the optimization calculation is carried out by using MATLAB software. The optimization results show that the multi-objective optimization design can effectively solve the design problem of cylindrical spiral compression spring, make its parameters more balanced, more in line with the actual working conditions of the spring and meet its working requirements.
