Design and Analysis of Personnel Airlock New Transmission Mechanism Development for Nuclear Power Plant

Using digital design method, a new transmission mechanism of personnel airlock is developed and the prototype modular design is completed. Using FMEA (failure mode and effects analysis) method, the weak links of the new transmission mechanism are found out, that is, the transmission chain of the locking mechanism, the door swing module and the bolt plug-in module after the earthquake. Respectively, using ADAMS dynamic simulation analysis software, the locking function and motion performance of the locking mechanism transmission chain are simulated and analyzed. Using ABAQUS finite element analysis software, the operability of the door swing module and the effectiveness of the bolt plug-in module after earthquake are analyzed. The results show that the transmission chain of the locking mechanism is properly selected, the door swing module meets the operational requirements, and the bolt plug-in module meets the effectiveness requirements. The transmission chain and structure of the new transmission mechanism developed are reasonable and meet the requirements of the third generation nuclear power.
