Abstract：Addressing the defect of conventional methods in capturing dynamic friction coefficient variations during drawer sliding processes,a dynamic analysis framework for dry-friction drawer systems was established by integrating finite element numerical simulation with a modified dry friction model.Systematic experimental comparisons validate the accuracy of the method in predicting dynamic behaviors.Results show that a significant negative correlation between friction coefficient and contact pressure,revealing the non-constant nature of friction.High consistency in dynamic response trends and key amplitudes between simulations and experiments,confirming method reliability and precision.The proposed"FEM coupled with modified dry friction model"approach effectively captures nonlinear friction-structure coupling during sliding,significantly enhances push-pull force prediction capability,and provides a theoretical tool for design optimization,user experience improvement,and lifespan prediction of drawer systems.
