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 the theory of heat transfer, considering the influences of different grinding parameters, coolant convection and ambient temperature on the temperature field, the finite element software ANSYS parametric design language APDL and its thermal transient analysis and solution technology are adopted. Simulation of temperature field of ultrahigh speed grinding workpiece. Through the research, it is found that the simulation results of ANSYS, the experimental measurement values and the numerical analytical solutions have the same trend under different grinding conditions, the error is small, and the temperature field in the grinding process is more accurately reflected than the analytical solution The law of change. The results of this study are instructive for the study of thermal state in grinding process, laying a solid foundation for exploring the thermal mechanism of grinding defects.
