Reliability Assessment of Simply Supported Beam Bridge Structural Performance Based on Load Tests
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Currently, bridge load tests use the verification coefficient to evaluate the structural performance of bridges in China, but this method is unsuitable. This paper presents a method that utilizes reliability to compare the actual bridge structural performance with the designed performance. Reliability functions for strain and deflection in load testing

Microstructure evolution of three-roll skew-rolling formed hollow axles with uniform wall thickness.
The International Journal of Advanced Manufacturing Technology, 2022 Abstract The uniform thickness hollow axle is one of the lightest weight axles in the high-speed rail industry. It can effectively reduce unsprung mass and further improve the train speed. Therefore, due to its importance and significance, it is crucial to research and develop the uniform thickness hollow axle. To understand the microstructural

Development of a Non-isothermal Forging Process for Hollow Axle Shafts
Procedia Engineering, 2017 Abstract This paper presents a novel non-isothermal forging process for a hollow axle shaft. The process consists of three operations: i) partially heat the initial tubular stock via induction heating, ii) deform the heated section into a solid, rod-like structure by upsetting the workpiece, and iii) shape the new ‘solid’ section into a flange by ...
