基于Ansys的带式输送机模拟摩擦系数研究OA

The running-resistance characteristics of belt conveyors directly govern the energy expenditure and economic performance of the system,wherein the simulated friction coefficient f constitutes a pivotal parameter.Conventional static postulates fail to capture the dynamic evolution of f under intricate operating conditions.The influence of disparate normal loads upon the transient development of f was reviewed.Based on the three-element Kelvin solid model,the characterization of the viscoelastic properties of the belt was conducted,a multi-physics coupled transient structural finite-element model of the belt-idler system was erected within Ansys Workbench,enabling a systematic simulation of the contact-mechanical interaction between belt and idler across variable load regimes.The current research elucidates the dynamic influence mechanism of load upon f,furnishing a theoretical foundation for precise resistance calculation,rational selection of driving power,and energy-conserving design of belt conveyors.Subsequent research will incorporate environmental temperature,material characteristics,and belt velocity,and a real-time predictive algorithm for dynamic f will be embedded within the intelligent control system,anticipated to further curtail the energy consumption of long-distance conveyors by 5%-8%.
