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。
Based on the principle of parallel mechanism, a three-dimensional parallel vibrating casting machine is developed. The designed three-dimensional parallel vibrating casting machine separates the supporting and exciting functions of the vibrating platform. The completely decoupled hybrid mechanism 2PRRR-P (2R) Excitation agencies to achieve dynamic platform along the X, Y, Z three directions reciprocating vibration. The model was built by CATIA 3D modeling software and imported into ADAMS to build its virtual prototyping model. The dynamic platform of the casting machine was simulated by kinematics, and the displacement curve of key points in the vibration platform of the foundry machine was plotted. Analysis, and then optimize the connecting rod design, the final design of a reasonable structure of the casting machine.
