Simulation and Experiment Study on Dynamic Characteristics of Multiple Gripper Linkage System
XIN Dezhong
Abstract：To counter to the defects of the existing gripper used for the mine drilling machine,the disk-spring normally-closed gripper and hydraulic clamping gripper were combined together to constitute a multiple gripper. The model and transfer function of the multiple gripper drilling linkage system were established, and analysis was made on the factors affecting the stability of the drilling linkage system. The model and calculation method of the gripper linkage system for drill unloading were put forward,and the transfer function of this system was established and analyzed. By taking some type of drilling machine as an example,the simulation verification was conducted for the system with the simulation software AMESIM. The experiments indicated that the gripper can work stably and reliable drill unloading can be achieved,this proved the correctness of the gripper and its linkage system.
