摘　　要：基于并联机构的原理,研制了一种三维并联振动铸造机,所设计的三维并联振动铸造机将振动平台的支撑和激振功能分离,以完全解耦的混联机构2PRRR-P(2R)作为激振机构,实现动平台沿X、Y、Z 3个方向往复振动。通过CATIA三维造型软件建立模型,导入ADAMS中建立其虚拟样机模型,对铸造机的动平台进行运动学仿真分析,绘制出铸造机振动平台工作过程中关键点处位移的变化曲线图,通过对图形的分析,进而对连杆进行优化设计,最终设计出结构合理的铸造机。A three dimensional parallel vibration casting machine was developed based on the principle of parallel mechanism. The support function and excitation function of the moving parts in the 3D parallel vibration casting machine was separated, and the composite group mechanism of full decoupling was acted as excitation mechanism to realize reciprocating vibration of the mobile platform along three directions of the X, Y, Z. A model was established by means of three-dimensional modeling software of CATIA, and the virtual prototype model was built up after importing ADAMS to analyze the kinematics simulation, draw the change rule curves of position of key points in the working process of machine mobile platform of the casting machine. Through the analysis of graphics, and then optimized design of connecting rod, a casting machine with reasonable structure was designed.
