裂纹条件下轴类锻件锻造中温度场分析模型
Temperature Field Analysis Model of Shaft Forgings with Cracks during Forging
摘要
Abstract
Based on the unsteady heat conduction theory,a temperature field analysis model of shaft forgings with symmetric and asymmetric cracks was proposed.The shaft forgings with cracks were considered as composite media.According to lumped parameter method,the temperature field function of crack was obtained through solving governing equation of forgings with symmetric cracks. Then the temperature field function of asymmetric cracks was obtained by introducing correction fac-tors.Moreover,the temperature field function of symmetric crack was regarded as the boundary con-ditions of heat conduction equation for shaft forgings with symmetric cracks.The temperature field function of asymmetric cracks was regarded as the boundary conditions of heat conduction equation for shaft forgings with asymmetric cracks.Therefore,combining with the corresponding boundary condi-tions,the temperature field analysis model of shaft forgings with cracks was established.The feasibil-ity of this model was verified according to experimental results.关键词
