Optimized design of induction coil for surface induction-hardening of high-speed railway axles
摘要
Abstract
Surface induction-hardening can enhance the surface resistance to fretting and impact of high-speed railway axles,comprehensively improve fatigue strength and extend the remaining service life while reducing axle weight for lightweight design.The surface induction-hardening process requires full-life-cycle service applicability design based on axle geometric dimensions and operational conditions,with the implementation methods and procedures also being critical aspects.Different load patterns and failure mechanisms exist in various axle sections of high-speed railways,along with irregular geometric features such as chamfers and arcs of varying sizes.induction coil design is essential to ensure the quality,efficiency,and energy consumption ratio of surface induction-hardening for high-speed railway axles.This paper presents induction coil design for a specific high-speed railway axle,including two types of scanning sensors(multi-turn coils and single-turn special-shaped coils)and stationary induction coil,detailing the design methods for each.A comparative analysis of their advantages and disadvantages is conducted,and the induction coil design is validated through full-scale axle surface induction-hardening tests.The induction coil design and optimization proposed in this study aim to provide an economical and efficient technical solution for the domestication of surface induction-hardening technology and equipment for high-speed railway axles in China,enhancing the core competitiveness of high-speed railway manufacturing.By leveraging technological innovation,this approach promotes low-carbon and green development in the manufacturing of key components and their full-life-cycle service.关键词
