Problems solved by technology

However, because the kinematic pair is realized in the form of ideal constraints, and the friction coefficient between entities is fixed during the simulation process, it is impossible to simulate the positioning relationship and friction coefficient changes caused by running-in and wear during the motion of the guide rail pair.

A sliding guide rail three-dimensional model is established in an ADAMS, generalized force is added to a sliding guide rail joint face, a guide rail pair model is established through a generalized force method, sliding guide rail simulation is rapidly achieved in a simple model form and a modeling method, and the friction wear effect is included.

Description

【Technical field】 [0001] The invention belongs to the technical field of simulation, in particular to an ADAMS-based sliding guide rail pair modeling method. 【Background technique】 [0002] Sliding guide rail is one of the most common forms of guide rail. Because of its simple structure and easy maintenance, it is widely used in various fields. However, since sliding guide rails generally have a large friction coefficient, they are prone to wear and tear, thereby destroying their guiding accuracy. Correctly predicting the wear of guide rails is of great significance for the design and use of guide rails. [0003] The use of software for dynamics simulation is one of the most commonly used means of mechanical system dynamics analysis. The use of simulation can quickly analyze the state of the mechanical system, thereby improving design efficiency and making reasonable predictions on the performance of the system. Among them, the multi-body dynamics simulation software ADAMS ...
