基于平面机构运动学理论建立了五杆多直线导向机构运动学模型，提出了由各构件运动方程生成该机构动画的新方法，并在MATLAB平台上开发了该机构动画仿真程序。提出了使用杆长不变条件检验该机构动画仿真程序和运动方程正确性的方法，并通过算例进行了验证。为该机构的应用提供了技术基础。 Kinematic equation of five-bar mechanism with multi-straight-line locus was derived from the theory of mechanics, and animation simulation for the mechanism was programmed by MATLAB language. Furthermore, the method based on bar-length invariance was presented to verify the validity of animation simulation program. The validity of above-mentioned kinematic equation and simulation program were proved by an example. The investigation provides technical basis for application of the mechanism.
