摘　　要：针对航空关键部件多维复合加载中高线性力加载的工况,提出6-SPS+P并联机构构型,实现对线性力、扭矩和弯矩的独立测量,可以满足线性力大量程和总体测量精度要求。分析机构工作空间,得出球铰链最大转角和支链长度的变化规律,确定机构几何参数。分析机构受力,确定各支链所受最大推力和拉力。In view of the condition of high linear force loading in multi-dimensional composite loading of key components of avi-ation, the configuration of 6-SPS＋P parallel mechanism is proposed to realize the independent measurement of linear force, torque and bending moment, which can meet the requirements of large range of linear force and overall measurement precision. By analyzing the workspace of the mechanism, the variation law of the maximum rotation angle of the spherical hinge and the length of the branched chain is obtained, and the geometric parameters of the mechanism are determined, thus this paper analyzes the force of the mecha-nism to determine the maximum thrust and tension of each branch chain.
