摘　　要：陶瓷零件快速成型机是基于层合速凝原理的,其成型工艺中浆料的填充和刮平过程十分重要。针对快速成型机的水平铺料机构,运用Workbench进行整机的有限元分析,得到工作状态下丝杠和导轨的变形,以及支撑板的变形与应力。通过ADAMS的动力学分析,得到料斗的速度和加速度曲线,以及丝杠和螺母,支撑板和导轨之间的受力情况。以此为基础,分析水平运动装置结构设计的合理性和可行性,以及在陶瓷零件成型过程中造成的影响,为尚处于设计阶段的结构的改进设计和精度提高提供了依据。The rapid prototyping machine for ceramic parts is based on the principle of laminated quick-setting, and the forming process of fiUing and leveling process is very important. Aiming at the horizontal pacing mechanism of the rapid prototyping machine, using Workbench for the finite element analysis, it gets the deformation of lead screw and guide at working condition, the stress and deformation of the brace. Through the dynamic analysis with ADAMS, gets the velocity and acceleration curves of the hopper, the force between the screw and nut ,the brace and guide. On this basis, analyzes the rationality and feasibility of structure design of the horizontal movement device, and the impact in the forming process of ceramic parts, provides the basis for structural design and accuracy improvement on the stage of design.
