摘　　要：在使用SLS快速成型机加工制造零件的过程中,由于粉床的预热温度分布不均匀,导致烧结制件的性能受到影响。通过对粉床预热温度场的有限元模拟,从理论上证明在粉床内部增加热源可改善温度场,研究通过温度补偿改善粉床温度的均匀性,从而提高烧结制件的质量,最后通过实验进行了验证。When using SLS rapid prototype machines to manufacture components, as the preheating temperature of the uneven distribution of powder bed, it will influence the performance of components. Through the finite element simulation to the preheating temperature field of the powder bed, the paper proved that it is a possible way to improve the temperature field by increases the heat source in the powder bed theoretically. Research showed that improving the uniformity of the powder bed through temperature compensation can improve the quality of components. Finally, the theory was verified by the experiments.[Ch,6 fig.1 tab.10 ref.]
