摘要

钢轨焊接接头必须进行焊后正火处理以提高接头性能，感应加热正火方式相对于火焰加热正火方式具有自动化程度高、正火质量稳定、作业环境好等优势，在钢轨现场焊接接头正火中越来越得到认可。重点研究了钢轨焊接接头感应加热电源的交流侧调功的PFM、PWM、PFM&PWM三种控制方法，通过建立三种控制方法的数学模型和MATLAB三维可视化分析，发现PFM&PWM控制方法在功率开关器件的开关损耗和功率调整过程中频率变化方面具有优势。基于此，提出了基于PFM&PWM控制方法的钢轨焊接接头感应加热电源的控制策略，并结合数学模型说明了其控制轨迹，同时，设计了基于TMS320F28335 DSP芯片的软硬件，实现了该控制策略的控制波形。为钢轨焊接接头感应加热电源的优化控制提供了理论支持，有助于提高钢轨焊接接头的性能和稳定性。

Abstract

In order to improve the performance of welded joints

the rail welding joint must be normalized after welding. Compared with the flame heating normalization method

the induction heating normalization method has the advantages of high degree of automation

stable normalizing quality

good working environment and so on. It is more and more recognized in rail field welding joint normalization. This paper focuses on the analysis of the PFM

PWM

PFM&PWM three AC side power regulation methods

the establishment of the mathematical model of the three control methods

and the use of MATLAB software to carry out three-dimensional visualization analysis of the mathematical model. The results show that the PFM&PWM control method has the advantages of less switching loss and less frequency change during power adjustment compared with the other two control methods. The control strategy of rail welding joint induction heating power supply based on PFM&PWM control method is proposed

and its control track is illustrated by combining with the three-dimensional mathematical model of rail welding joint induction heating power supply; The software and hardware based on TMS320F28335 are designed to realize the control waveform of the control strategy.
