摘要
建立舱口下开盖的扭转弹簧平衡机构和连杆弹簧平衡机构的力学模型,对比分析这2种平衡机构的力矩与反向重力矩的匹配程度,结果发现,连杆弹簧平衡机构对舱口下开盖的重力平衡效果更优。为减小舱口下开盖启闭过程中人员的操作力矩,将连杆弹簧平衡机构作为优化设计对象,建立以操作力矩最大值最小为目标的优化数学模型。为适应工程设计的要求,通过添加整数约束,采用变量映射的方法将优化变量转换为连续整数,并采用遗传算法求取某型舱口下开盖重力平衡机构的最优解。
Mechanical models of torsion spring balance mechanism and linkage balance mechanism with cylindrical spring are created for bottom hatch cover.It is found that the optimal balance mechanism is linkage with cylinder spring based on the match degree comparison of opposite gravity torque on the two mechanisms.To reduce the manual torque for opening and closing bottom cover,mixed integer nonlinear programming model of linkage with cylindrical spring is created to minimize the maximum of manual torque,and the methods of integer constraint and variable map are used to make the consecutive integer solution results corresponded to design requirements in engineering.Base on the special bottom cover,genetic algorithm is used to get the optimal solution of the linkage mechanism with cylindrical spring.
