摘要
文章利用有限元法研究了含橡胶连杆平行四边形机构的非线性动力学行为.通过动力学分析软件建立了含橡胶连杆平行四边形机构的刚柔耦合模型,对比分析了全刚体机构和刚柔耦合机构的从动曲柄质心的位移、速度、加速度和角速度的变化,采用相图法和最大Lyapunov指数法分析了系统的运动稳定性.研究结果表明:含橡胶连杆的平行四边形机构的刚柔耦合模型的动力学行为与全刚体模型的动力学行为相比有很大的不同,且含橡胶连杆的平行四边形机构刚柔耦合模型中从动曲柄的运动是混沌的.
The dynamic behavior of the parallelogram mechanism with rubber linkage was presented and discussed in the paper.The rigid-flexible coupling model of the parallelogram mechanism with rubber link is established by dynamic analysis software.The displacement,velocity,acceleration and angular velocity of the driven crank centroid of the whole rigid body mechanism and the rigid flexible coupling mechanism are compared and analyzed.The motion stability of the system is analyzed by phase diagram method and maximum Lyapunov exponent method.The results show that the dynamic behavior of the rigid-flexible coupling model of the parallelogram mechanism with rubber link is quite different from that of the whole rigid-body model,and the motion of the follower in the rigid-flexible coupling model of the parallelogram mechanism with rubber link is chaotic.
