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
