摘要/Abstract

摘要： 基于广义杆组提出了一种对多环路三移一转位移输出机构型综合的新方法。该方法把运动链当成广义杆组逐个添加在输出构件上，进一步扩展了Assar杆组法在空间的应用。分析了单环路到多环路杆组自由度与输出构件自由度和位移参数的关系，得到了添加自由度为0的广义杆组对输出构件自由度和位移参数的变化关系。综合了三移一转位移参数的杆组，建立了交集运算规则。通过组合两个广义杆组综合输出构件自由度为2、3、4单环路机构，再添加自由度为0广义杆组，得到了双环路机构。通过自由度为0广义杆组综合出多环路机构的例证，展现了该方法在空间机构综合方面的全面性和有效性。

Abstract: A new method to synthesize multi-loop mechanisms with three translational and one rotational displacement parameters is proposed in this paper. This method is based on generalized link group. It extends the unified link groups in plane and space by using kinematic links as a generalized link group added one-by-one to the output link. The internal relation on the change in the degree of freedom (DOF) and displacement parameters of the output link after adding a 0-DOF generalized link group are analyzed. The link groups with three translational and one rotational displacement parameters are synthesized, and its intersection operation rules are established. The 2-, 3-, and 4-DOF single-loop mechanisms are obtained by combining two generalized link groups. The dual-loop mechanisms are synthesized by adding a 0-DOF generalized link group. The multi-loop mechanisms are obtained by adding 0-DOF generalized link groups. Some novel mechanisms are synthesized to illustrate the effectiveness and comprehensiveness of the proposed method.

Key words: displacement parameter, generalized link group, multi-loop, three translational and one rotational, type synthesis
