摘要
针对传统方法难以捕捉抽屉在运动过程中摩擦系数动态变化这一缺陷,基于有限元数值模拟方法,结合修正的干摩擦模型,建立了干摩擦抽屉系统的动力学分析框架。通过系统性的实验对比,验证了该方法在预测系统动态行为中的准确性。研究结果表明:干摩擦抽屉系统中,摩擦系数与接触压力呈显著负相关,揭示了摩擦行为的非恒定特性;仿真与实验结果在动态响应趋势及关键幅值上高度吻合,证明了方法的可靠性与精度;所提出的“有限元数值模拟耦合修正干摩擦模型”方法,有效捕获了滑动过程中非线性干摩擦行为与结构动力学的耦合效应,显著提升了对干摩擦系统推拉力的预测能力,为抽屉系统设计优化、体验改进与寿命预测提供了理论工具。
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.
