For the complex transmission and greater weight, traditional half-rotating mechanism (HRM) is not suitable for flight. The simplified HRM with local constraint is proposed as the driving mechanism of HRW in this paper. The performing process and characteristics of local constraint was further given. According to the contact state between moving components, the performing process of local constraint was divided into four stages. The error models of half-rotating rod angle under different stages were respectively established. Case study was also given to verify the availability of error models. On the basis of analysis models mentioned above, the structural parameters of some key components were optimized to decrease rotating angle error and improve running stability of driving mechanism. The research results indicated that the simplified HRM with local constraint was useful to design driving mechanism of HRW %K 半转翼 %K 驱动机构 %K 局部约束 %K 转角偏差 %K 优化设计< %K br> %K half-rotating wing %K driving mechanism %K local constraint %K rotating angle error %K optimization design %U http://journals.nwpu.edu.cn/jxkxyjs/CN/abstract/abstract6749.shtml
