摘要
为合理规划装备制造过程中常用的T形管环状接头焊接路径,提出了一种基于有限元Simufact.Welding和Matlab模拟平台,引入约束因子和改进信息素的更新规则,对传统蚁群算法进行改进,以提高蚁群算法信息素的更新效率,并增强该算法在连续空间路径的搜索能力。该方法建立了T形管环状接头的焊接仿真,并对其相应的焊接路径分别进行分析,结果表明:相较于传统的蚁群算法,基于改进型蚁群算法所得的焊接路径不仅节约了时间资源,而且减少了焊丝耗材的浪费。同参数、同条件下,焊接的工作效率同比提高7.79%,三维焊接路径移动距离同比减少6.31%,且提高了2.92%的可靠性。因此,该方法对优化T形管环状接头的焊接路径有效且可行。
For reasonable planning of commonly used in the process of equipment manufacturing T-type pipe ring joint Welding path. This paper puts forward a kind of based on finite element Simufact. Weldingand Matlab simulation platform,the introduction of the constraint factors and improved pheromone update rule,to improve the traditional ant colony algorithm,in order to improve the update efficiency of pheromone of ant colony algorithm,and enhance the path of the algorithm in the continuous space search ability. The method to establish the T-type pipe ring joint welding simulation,and analyzes its corresponding welding path respectively,the results show that compared with the traditional ant colony algorithm,based on improved ant colony algorithm of welding path not only saves time resources,and reduce the waste of wire material. Parameters and condition,the welding efficiency increased by 7. 79%,compared to the 3-D welding path Movement distance,fell by6. 31%,and to improve the reliability of 2. 92%. As a result,the method for optimization of T-type pipe ring joint welding path is effective and feasible.
