Design of Control System for Test Platform of Nuclear Fuel Gripper

As the key component in the fuel handing and storage system,the test on the function and durability of the fuel gripper is very important.Considering the actual work conditions of the gripper and using the programmable logic controller,the raising-lowering of the load and the locking and unlocking the gripper are implemented by the hydraulic drive and the pneumatic drive respectively.The design of the electrical hardware,PLC software and human machine interface software are also presented,and the test platform is established.The application shows that the control system of this test platform is with flexible control,convenient operation and high reliability.
