Half-rotating wing (HRW) is a new kind of flapping wing system with rotating-type flapping instead of oscillating-type flapping. For the complex mechanical transmission and high weight which is not suitable for flight of traditional half-rotating mechanism (HRM).The simplified HRM with local constraint was proposed as the driving mechanism of HRW in this paper. The performing process and characteristics of local constraint was further given. According to contact state between moving components, the performing process of local constraint was divided into two stages. To analyze the influence of local constraint on the driving torque exerted in the crank of driving mechanism, the model of driving torque under different stages were respectively established. Based on the model, the change curve of driving torque was obtained through simulation by MATLAB, which showed that local constraint had little influence on driving torque. The results could provide guidance for the choice of motor of HRW and optimization of dynamics.
