Manufacturing Process of Straddle Monorail Beam-switching Turnout

Abstract

[Objective] Due to the diverse components, complex internal structures, and significant deformation risks of straddle monorail beam-switching turnout, issues such as improper component installation, welding-induced thermal deformation, and stress concentration may arise during the manufacturing process, leading the products failure in meeting the required design quality. Therefore, it is necessary to conduct a systematic study on the manufacturing process of the straddle monorail beam-switching turnout. [Method] The overview of straddle monorail beam-switching turnout is presented. The structural characteristics and material properties of the straddle monorail beam-switching turnout are analyzed. Targeted research is conducted on manufacturing challenges, process route planning, process design, fixture design, and other aspects. A set of manufacturing processes suitable for the straddle monorail beam-switching turnout is proposed, and the implementation effects of the proposed manufacturing process are verified. [Result & Conclusion] The adopted fixture frame and welding process can control the dimensional accuracy of each component within the design requirements. Coupled with vibration aging treatment, it effectively improves the distribution state of structural stress and reduces the risk of residual deformation after welding, so as to ensure that the linear dimensions of the turnout meet the standards after assembly.
