利用ANSYS软件对通勤车转向结构的 fatigue strength calculation and analysis

简介：
fatigue strength analysis of the trains turning architecture is a critical step to ensure the safety of its operation. This study, conducted in the context of urban high-speed rail systems, focuses on evaluating the fatigue strength of the trains turning architecture using ANSYS software. Based on the UIC 615-4 standard, a detailed finite element analysis was performed to assess the fatigue performance under various loading conditions. The train, operating at a speed of 160 km/h with a maximum wheel load of 16 tons, serves as a key component in urban rapid transit systems. The turning architecture is designed to handle diverse and complex loading scenarios, including vertical, horizontal, and asymmetric loads, as well as static and dynamic loads from electric motors and gearboxes. The structure itself is an integral part of the trains frame, comprising two side beams and two cross beams. The side beams are constructed as closed-cell box sections, while the cross beams are made from seamless steel pipes. The entire framework must meet stringent fatigue strength requirements to ensure long-term reliability and safety. With advancements in computational methods and software like ANSYS, finite element analysis has become a powerful tool for evaluating fatigue performance. By establishing a three-dimensional finite element model of the structure and simulating its behavior under different loading conditions in ANSYS software, it is possible to analyze stress distribution patterns under various operational scenarios
