摘要
In this study, the model of new hydraulic bilateral rolling shear is researched based on kinematics theory of a hybrid spatial linkage mechanism. Combined with research method of 3-RRR planar parallel mechanisms kinematic, the relationship between cylinder displacements and blade positions of the shearing mechanism is developed. Nonlinear system stability of the shearing mechanism in a new hydraulic bilateral rolling shear is researched based on Krasovskii method, the result shown that the system is stable and reliable. Moreover, based on the bilateral rolling shear of a large steel company, the displacement of cylinders is obtained through experiments. Compared with differential between the theoretical formula and the actual value, the differential is small. This study has certain instruction to the design and the development of similar product and it also has a higher practical value to the general industrial production.
