摘　　要：改进了平面机构运动分析的复数矢量法,并应用于航母喷气偏流板装置七杆执行机构的运动分析。介绍了复数矢量法并将其扩展,实现了利用复数表示矢量的点乘和叉乘,给出了基于改进复数矢量法推导航母喷气偏流板装置的运动方程,计算得出了解析解,在给定的结构参数下利用MATLAB对喷气偏流板装置进行计算得出了机构的运动线图,验证了基于改进复数矢量法进行机构运动分析的有效性与正确性。The complex vector method of the motion analysis of the plane mechanism is improved, and it is applied to the motion analysis of the seven-bar actuator of the aircraft carrier jet blast deflector. Firstly, the complex vector method is introduced and extended to realize the dot product and cross product of vectors expressed with complex numbers. Secondly, the motion equation of the aircraft carrier jet deflector device is derived based on the improved complex vector method, and the analytical solution is obtained. Finally, MATLAB is used to calculate the jet blast deflector device under the given structural parameters, and the motion line diagram of the mechanism is obtained. The effectiveness and correctness of mechanism motion analysis based on improved complex vector method are verified.
