摘要：

针对剑杆织机打纬凸轮副接触碰撞建模及仿真验证比较困难的问题,探讨便捷有效的接触碰撞力建模方法。首先,基于L-N接触碰撞模型,在现有接触碰撞力混合模型的基础上,改进并建立适用于打纬凸轮系统的接触碰撞力模型,进而对碰撞力及碰撞变形进行求解;其次,应用瞬态碰撞分析软件ANSYS/LS-DYNA并配合可视化软件LS-PrePost,对模型计算结果进行仿真验证;在验证结果的正确性后,分别计算碰撞初速度和碰撞点曲率半径对碰撞力和变形量的影响程度。结果表明:碰撞初始速度和凸轮曲率半径都会对碰撞过程动态响应产生影响,但碰撞初速度对系统碰撞力和碰撞变形量影响更为明显。

关键词: 剑杆织机, 打纬凸轮, 接触碰撞力模型, 碰撞变形, 碰撞初速度

Abstract:

Aiming at the difficulty in modeling the contact force generated by the beating-up cam in rapier looms, this paper reports on a convenient and effective method for simulating the contact force. Based on the L-N contact-impact model and the existing mixed model of contact-impact force, the contact-impact force model suitable for the beating-up cam system is improved and established, which helps solve the impact force and deformation. The transient impact analysis software ANSYS/LS-DYNA and the visualization software LS-PrePost are used to simulate and verify the calculation results of the model. After validating the modelling results, the influence of the initial impact velocity and the curvature radius of the impact point on the impact force and deformation is calculated respectively. The results show that both the initial impact velocity and the radius of cam curvature have notable influence on the dynamic response of the impact process, with the initial impact velocity having more obvious influence on the impact force and the deformation of the system.

Key words: rapier loom, beating-up cam, contact force model, impacting deformation, initial impact velocity
