摘要

摘要: 设计了一种新型飞机机翼支撑平台，其主要结构为并联机构。该并联机构由动平台、静平台和两者之间3条相同的PRS支链组成，具有适用飞机机型多的优点，并研究了其尺度综合方法。在建立并联机构的静力雅可比矩阵基础上，提出当动平台所受外力和外力矩变化时，支链驱动力和约束力变化量的最大全域均值最小的静力学性能评价指标。同时兼顾具体工作实际给出约束条件，利用单调性分析的方法，研究了并联机构静力学性能和各约束条件随尺度参数的变化规律，进而寻求满足约束条件的最优尺度参数。最后通过算例验证了该尺度综合方法的有效性。

Abstract: A new type of aircraft wing support platform is designed. The main structure is a parallel mechanism composed of a moving platform, a static platform and three identical PRS branch chains, being more suitable for aircraft models. A method for the dimensional synthesis of the parallel mechanism was proposed. When the moving platform is under force and torque change, a static performance evaluation index is proposed to minimize the maximum actuation and the constraint force of the links by using the static force Jacobian matrix of the parallel mechanism. Taking into account the actually required constraints, we use the monotonic analysis to study the parallel global static performance and the constraint conditions that have varying scale parameters in order to optimize the scale parameters of the conditions. Finally we prove the effectiveness of the method with numericalexamples.
