摘要

对注射机五铰链斜排双曲肘增力机构进行了运动和力学特性分析

使用改进蚁群算法对该增力机构进行了优化设计

以机构行程比较大、力的放大倍数较大和机构总长较小为目标函数建立了优化数学模型

该优化设计属于多目标函数优化问题

通过对增力机构实例计算与传统设计方法进行了比较

结果表明机构总长减小的同时

行程比及力的放大倍数都有明显提高。

Abstract

The analysis of motion and mechanics property is carried out on the five hinged incline arranged and double elbowed force increasing mechanism of injection machine.A complete optimal design procedure is carried out by using improved ant colony algorithms

so as to increase the stroke ratio and the amplification of the force

and to decrease the total length of mechanism.Its optimization mathematics model is established.The procedure of optimal design belongs to multi-object optimization problem.The optimal solution of the force increasing mechanism is found by improved ant colony algorithms.Compared with the traditional methods

the result shows that the total length of mechanism is decreased

the stroke ratio is increased

and the amplification of the force is increased.
