摘要
根据传热学的有关理论,综合考虑了不同磨削参数、冷却液对流以及环境温度对温度场的影响,采用有限元软件ANSYS的参数化设计语言APDL及其热瞬态分析求解技术,实现了超高速磨削工件温度场的仿真。通过研究发现,ANSYS的仿真结果与实验测量值、数值解析解在各种不同磨削条件下都具有相同的变化趋势,误差很小,且比解析解更精确地反映了磨削过程中温度场的变化规律。该研究结果对磨削过程热状态的研究具有指导意义,为探索产生磨削缺陷的热机理打下了坚实基础。
According to heat transmission theory, taking different grinding parameters and the influence upon tem- perature field caused by liquid coolant convection and ambient temperature into consideration, adopting APDL and its transient heat analysis technology, the simulation of the ultra high speed grinding temperature field is achieved. The study shows that the error between the simulation results of ANSYS and the experimental measuring results is small. Compared with analytic solutions, ANSYS reflects the change rule of the ultra high speed grinding temperature field more precisely. The study have great meaning in grinding process study of heat state, and it will help to find the heat mechanism to decrease grinding defects.
