Optimization and Analysis of the Response Surface of the Sealing Ring for the Autonomous Filling Arm of Oil Tank Trucks
In order to improve the sealing performance of the front-end quick connect device of the autonomous refueling arm of oil tank trucks,an internal expansion rubber sealing ring is designed,and the sealing ring is optimized and analyzed using response surface method and finite element method.Firstly,based on the finite element software ANSYS Workbench,the sealing ring is modeled and simulated,and the effects of the rounding radius,thickness,and compression amount of the sealing ring on its performance are studied.Then,taking the contact area,contact pressure,and equivalent stress between the sealing ring and the pipe wall as optimization objectives,an optimization model of the sealing structure is established using Design-Expert software,and the optimal design scheme is obtained through multi-objective optimization.Finally,the performance of the sealing rings before and after optimization is compared and analyzed.Numerical tests have shown that under a maximum medium pressure of 3 MPa,the contact pressure of the optimized sealing ring has increased by 1.3 MPa,resulting in a larger effective contact area and a more concentrated contact zone,which is conducive to achieving effective sealing of the quick connect device and the tank opening of the oil tank truck.In addition,the equivalent stress has been reduced by 4.3％,which helps to extend the service life of the sealing ring.
