摘　　要：综合考虑补偿滑轮组变幅机构载重水平轨迹落差和不平衡力矩多目标问题,引入物理规划法,该方法是一种高效的多目标优化设计方法,考虑到了设计者的偏好和满意度,建立了基于物理规划的补偿滑轮组变幅机构优化模型,克服了传统补偿滑轮组基于单目标优化选取的不足。实例分析表明,该方法不仅可提高设计质量,而且更能反映设计者和用户的需求,可为补偿滑轮组变幅机构及其他机构产品的设计提供一种新的途径。With compensation for the level fall due to heavy loaded derricking gear with compensation assembly pulley and imbalance moment considered as the multi - objective optimization functions, and this paper discusses optimization of derricking gear with compensation assembly pulley based on physical programming, while combining personal preference and design＇s satisfaction. It can be used to overcome defects in classical single - objective design of derricking gear with compensation assembly pulley. Practical example analysis shows that this approach can not only improve the quality of design, but also meet requirements of designers＇ and customers＇needs.
