Abstract:Aiming at the problem that the matching speed of the servo tank accumulator assembly is slow and the matching parameters are single, a comprehensive quantitative scoring system considering three matching parameters (fit gap, X-ring compression ratio, stretch ratio) and the importance distribution of seal pair is proposed. The sealing performance of the matching parts is comprehensively scored, and then several combinations with the highest scores are selected to achieve an optimal matching of parts. The process can be implemented by Matlab programming to improve the matching speed. For the problem that the axial force extraction in the tank accumulator assembly simulation is difficult, by introducing the driving component, the axial contact pressure during the assembly process can be obtained, and finally converted into the axial force. Combing the optimal matching function with assembly simulation function, a X-ring matching simulation platform based on Matlab GUI (Graphical User Interface) is developed. The software is easy to operate and the simulation results are easy to extract.
