摘　　要：熔融沉积快速成型是一种重要的快速成型技术,针对成型件的成型精度问题,在分析了成型工艺参数的基础上,提出了对扫描速度进行深入研究.建立物理模型并进行网格划分,在ANSYS经典版的基础上,利用高斯热源移动技术,合理的描述出熔融沉积快速成型的形成过程,并进行模拟仿真.仿真结果表明:在成型过程中选择合理的扫描速度可以降低成型件的翘曲变形,是有效解决成型件的成型精度这一问题的途径,这将为以后的实际应用奠定理论基础.Fused deposition molding is an important kind of rapid prototyping technology. In view of the forming precision of the problem, and on the basis of the analysis of the forming process parameters,it suggested that the thorough research on the scanning speed be conducted. Physical model was established and meshing was made. Based on the classic version of ANSYS, using a Gaussian heat source moving technology,the formation process of the fused deposition rapid prototyping was reasonably described, and the simulation was carried out. The simulation results show that the chosen reasonable scanning speed in the forming process can reduce the warp deformation, in which way the problem of molding precision is effectively solved, providing the theoretical basis for the practical application in the future.
