As the core component of stud tensioner,the hydraulic driving device plays an important part in the sealing of RPV. This article completes the principle analysis and structural design of the hydraulic driving device of smaller nuclear stud tensioner. Using the four stage cascade hydraulic cylinder as main drive, it determines the main structural parameters by preliminary calculation. The preliminary design is analysed by FEA software,and optimized according to the results. Then presents the optimal parameters,and lays good foundation of futher technology optimization and performance enhancement.
