Abstract

This article conducts a systematic study on the abnormal phenomena occurring at the end of the press fitting process for HXD3 and HXD3C electric locomotive axles. Firstly, an in-depth analysis is conducted on the various abnormal manifestations that occur at the end of the press fitting process, focusing on multiple dimensions such as the accuracy of tooling equipment, process parameter settings, and material characteristics of axle components. Secondly, considering the actual operating conditions of the locomotive, a comprehensive risk assessment is carried out on potential safety hazards such as axle loosening and increased operational vibration that may be triggered by these abnormal phenomena. Based on this, improvement measures are proposed, covering aspects such as process optimization, tooling upgrades, and the improvement of quality inspection standards. At the same time, directions for further research and verification are clarified. Through continuous experimental demonstration and data accumulation, a complete solution is formed, aiming to fundamentally and thoroughly solve the abnormal problems occurring at the end of the axle press fitting process and ensure the safety and stability of locomotive operation.
