中文摘要:

以便提高外部坚硬和力量,一条大规模水力的门轨道应该通过热处理。水力的门车轮和轨道的当前的设计方法基于赫联系线性有弹性的理论,并且不在热处理引起的材料的机械性质考虑变化。在这研究,热处理参数根据车轮和轨道的适用的机制被设计并且分析。磁道的熄灭的进程被 ANSYS 程序模仿,并且温度变化,剩余压力,和变丑被获得并且分析。冶金在热处理以后的结构地被方法基于 time-temperature-transformation (TTT ) 预言曲线。结果证明分析方法和设计磁道热处理过程是可行的,并且能为实际工程提供引用。

英文摘要:

In order to enhance external hardness and strength, a large-scale hydraulic gate track should go through heat treatment. The current design method of hydraulic gate wheels and tracks is based on Hertz contact linear elastic theory, and does not take into account the changes in mechanical properties of materials caused by heat treatment. In this study, the heat treatment parameters were designed and analyzed according to the bearing mechanisms of the wheel and track. The quenching process of the track was simulated by the ANSYS program, and the temperature variation, residual stress, and deformation were obtained and analyzed. The metallurgical structure field after heat treatment was predicted by the method based on time-temperatuxe-transformation (TTT) curves. The results show that the analysis method and designed track heat treatment process are feasible, and can provide a reference for practical projects.
