“…Their research is helpful to predict the joint wear of mechanical systems with clearance and optimize the mechanism in the design. Xu et al [42] simulated the clearance revolute joint with constantly updated wear profile in a crank-slider mechanism by comparing the theoretical and experimental results, confirming that wear in a revolute joint will increase the clearance and further deteriorate the dynamic performance of the multibody system.…”

This paper studies the effect of wear that occurs in the contact between pin and bushing in revolute joints with clearances due to manufacturing tolerances, and the evolution of the size and shape of the free spaces with the work cycles. The objective is to propose an efficient method to estimate, during the design procedures of a machine or mechanism, the variation of the clearance and its shape. Ease of analysis and efficiency is prioritized over accuracy, which anyway must be kept within admissible levels. In order to streamline the application of the method to any multibody system, SolidWorks has been used for design and multibody simulations, and Excel for calculation of the wear suffered by the joints.

“…Wang and Liu 23 studied the wear behavior of five-bar system with clearances, the results showed that the multi-clearance joints produced stronger impact-collision forces, leading to more serious wear behavior, but the existence of flexible rods can reduce this effect. With the development of the dynamic theory of multisystems with clearances, the experimental research on clearance dynamics has also made great progress, such as the crank-slider systems with clearances, 24,25 planar 4 bar mechanism, 26 the three-joint locking mechanism in the cabin door, 27 etc. have conducted experimental research, and the experimental results are consistent with the results of the built wear prediction model.…”

An approach for analyzing and quantifying the irregular wear effect of planar multi-body mechanical system with multi-clearances is proposed. The classical planar four-bar linkage is used as a demonstrative example to study the mechanism of irregular wear effect of multi-body system with multi-clearances. The system dynamic equation is established using Lagrange multiplier method, the contact force and friction in the process of contact collision are respectively modeled using the Lankarani-Nikravesh (L-N) nonlinear contact force and LuGre models, and the wear depth prediction model for multi-clearance joints is built based on Archard’s equation. The influence of the crank speed, clearance number, clearance position and clearance size on the wear effect of multi-clearances system is comprehensively studied. Numerical simulation results show that the wear depth joint increases with increase of crank speed, and there are significant differences in the wear depth of different clearance joints. When the clearance size changes, the significant nonlinear wear phenomenon appears at different joints, when the clearance size of different joints meets a certain proportion, the system wear phenomenon is the least. The obtained valuable results provide important theoretical support for the optimal design of multi-clearance joints system.
