针对生活及工业气球的充气打结工作存在的效率和环保问题,从创新设计和绿色设计出发,提出了一种由多种机械传动结构配合的设计方案。并以核心部件圆柱槽型反凸轮为例,阐述设计过程中采用的参数化设计方法,用函数表达式控制机构实现精确运动。此基础上深入研究基于参数驱动的优化设计,利用MATLAB优化工具箱中的遗传算法以反凸轮机构最小阻力矩为目标进行优化,修改模型并用优化结果重置参数,通过功能样机试验和UG软件中的Recur Dyn解算器的运动分析进行验证,完善了整个参数化驱动的优化设计。
Considering the efficiency and environmental issue in balloon inflating and sealing up work,an innovate design scheme cooperated by a variety of transmission structure which is ingenuity and meets the green design concept is put forward. Taking the core component cylindrical cam as an example and the parametric design analysis in its process is expounded and the mechanism is controlled to achieve precise movement by using function expression. On this basis,the optimization design based on the parameter- driven is further studied,by using the genetic algorithm in Matlab optimization toolbox and taking the resistance moment of inverse cam mechanism as objective,the model is modified and the parameter is reset by using the optimization result. The verification is carried out through the functional prototype testing and motion simulation analysis in Recur Dyn solver in UG software,and the optimized design in all the parameter driving is perfected.
