摘　　要：提出了一种新型的RSRR揉面机构.采用约束螺旋理论进行机构自由度分析,表明RSRR机构有1个公共约束,是5阶机构,有1个自由度.采用齐次坐标变换法建立了机构的多刚体运动模型,在运动学分析的基础上实现了机构的尺寸综合.通过数值仿真和虚拟样机运动仿真及干涉检查技术,有效地实现了RSRR揉面机构设计.A novel RSRR kneading mechanism is proposed. The constraint screw theory is adopted to analyze the degrees of freedom. The RSRR mechanism has a common constraint, is a fifth-order mechanism, and has one degree of freedom. The method of homogeneous coordinate transform is used to establish the multi-body kinematics model. The dimensional synthesis of the mechanism is achieved based on the kinematic analysis. The techniques of numerical simulation, virtual prototyping and interference detection are utilized to implement the design of the RSRR kneading mechanism effectively.
