摘要：
In order to meet the urgent demand of variable sweep aircraft in wide speed range, a kind of driving mechanism suitable for distributed driving of locally rotating variable sweep wing was designed. Taking the transmission performance as the index, the dimension of the unit driving mechanism was preliminarily designed, and then the SQP (sequence quadratic program) algorithm was combined to optimize the dimension of the mechanism with the energy conversion rate of the whole process of mechanism deformation as the optimization objective. The output work of the optimized driving mechanism under constant force was increased by 44.3%, the energy conversion rate was increased by 37.5%, and the driving distance was shortened by 9.7%. To solve the problem of how to distribute the driving force of multiple driving chains, a quasi-static driving force solution method was proposed by combining the force method of analyzing the internal force of statically indeterminate structure with the traditional force analysis method of mechanism. The driving force of the four wing beam models under certain load and component material conditions was calculated, and the dynamic simulation experiment was carried out based on ADAMS (automatic dynamic analysis of mechanical system) to verify the accuracy of the driving force distribution model. The error analysis showed that the calculation error of the quasi-static driving force of the model was less than 5.5%. Finally, based on the simulation results and the weight of the driving mechanism, the number of driving chains was optimized, and the optimal number of driving chains was determined to be 3. © 2023 BUAA Press.
