Research on critical components load on 160 km/h rigid suspension contact system
To ensure the safe and stable operation of the 160 km/h rigid suspension contact system,the selection and technical parameters of its key components are crucial.This study is based on the finite-element analysis method to model the key components of the rigid suspension contact system.Based on the time-domain characteristics of load under measured working conditions,the ultimate load-bearing capacity of key components was analyzed through load fatigue theory and static simulation.The analysis results not only reveal the performance of key components in actual operation,but also provide a scientific basis for optimizing design and material selection.Meanwhile,through multiple iterations of simulation calculations,the optimal materials and geometric parameters of key components are determined to effectively resist fatigue failure and sudden loads during long-term operation.Experimental verification shows that the optimized key components exhibit excellent stability and durability in practical applications.This achievement can lay a solid theoretical and practical foundation for the design of higher-speed suspension systems in the future,ensuring the reliability and safety of train operations at high speed.
