Fuel assembly anti-pinning experimental device

Abstract

The application discloses a fuel assembly anti-hooking experimental device, which comprises a positioning mechanism, a simulation mechanism, a plurality of transverse loading mechanisms, a lifting mechanism and a leveling and centering mechanism. The fuel assembly anti-hooking experimental device applies transverse load to the fixed simulation body through the transverse loading mechanism, so that the fixed simulation body is in contact and friction with the movable simulation body, thereby simulating the contact characteristics of the movable part and the fixed part in the loading and unloading process of the fuel assembly. The movable simulation body is lifted or inserted downward at a characteristic speed by the lifting mechanism, thereby simulating the hooking process of the fuel assembly. In this way, the economy is ensured, and the fuel assembly hoisting and hooking process can be accurately simulated, so that experimental data in the experimental process are obtained, a basis for verifying the anti-hooking performance of the fuel assembly structure is provided, and the anti-hooking performance of the fuel assembly can be effectively verified. Meanwhile, the fuel assembly anti-hooking experimental device also ensures the overall leveling and centering of the experimental device through the leveling and centering mechanism.
