摘　　要：针对仿鸟扑翼机构设计中对空气阻力以及机构零件强度的严格要求,提出了一种基于Pro E的对空间四连杆扑翼机构的受力分析方法。首先,对仿鸟扑翼机构及翅翼进行必要的简化;其次,将机构运动情况和空气阻力引起的阻力矩进行耦合,得出阻力矩关于从动件运动速度的函数;最后在Pro E中设置参数,实现受力分析,并得出可用于校核零件强度的受力分析数据。结果表明,该方法应用于仿鸟扑翼机构的受力分析可以简化设计流程,提高设计效率。According to the strict requirements of air drag and the strength of mechanical parts of the design of bird-like flapping-wing mechanism,we propose a method for Force Analysis of spatial four bar linkage flapping-wing mechanism based on ProE.Firstly,make a necessary simplification for the bird-like flapping-wing mechanism and the bird-like. Next,analyze the movement of the mechanism and the moment of resistance caused by air drag,and find out the moment function of follower motion speed. Finally,set parameter values in ProE to realize the force analysis,and then obtain the data which can be helpful to checking the strength of mechanical parts. The results show that this method for force analysis of spatial four bar linkage bird-like flapping-wing mechanism can simplify the design process and improve the design efficiency.
