摘要
针对空间四连杆引纬机构的引纬要求,用PROE建立该机构的三维实体模型,生成空间四连杆引纬机构的刚体模型,并选取叉形架作为柔性体,用ANSYS划分网格,生成中性文件,然后导入ADAMS中替换刚性叉形架进行柔性动力学联合仿真,最后将仿真生成的载荷文件添加到ANSYS叉形架中,对其进行应力分析。与刚性动力学仿真数据相比,柔性动力学仿真的位移和速度曲线平滑度好,但加速度曲线局部有波动。对叉形架进行的有限元应力分析显示3个连接点处应力最大。此研究结果可为引纬机构后续的优化设计提供参考。
As for the requirement of the weft insertion mechanism of spatial four bar linkage, this paper buih three-dimensional solid model of this mechanism with PROE, generated the rigid body model of the spatial fnur bar linkage weft insertion mechanism, and selected the fork frame as a flexible body, which was meshed in ANSYS, replaced the rigid fork frame in ADAMS with the neutral file, then the simulation for spatial four bar linkage mechanism would be made by flexible dynamics analysis method based on ANSYS and ADAMS, load flies generated by the simulation would be added to the ANSYS fork frame, and its stress analysis would be made later. Compared with the rigid dynamics simulation data, displacement and velocity curve of flexible dynamics simulation had good smoothness, but acceleration curves had local fluctuations. The maximum stress occurred at the three connection points of fork frame finite element stress analysis. This study provided an efficient simulation method for spatial four bar linkage weft insertion mechanism, and provided a reference for the optimized design of the follow-up uf the weft insertion mechanism.
