[PERSON], [PERSON] et al. [6] identified two critical locations where O-rings may experience failure in static sealing structures. [PERSON], [PERSON] et al. [7] introduced a novel stress analysis model for O-rings, effectively revealing the stress distribution in static sealing structures with different material properties. [PERSON], [PERSON] et al. [8] proposed a reliability-based method to analyze the influence of the randomness of rubber material parameters on the performance of O-rings in static sealing structures. [PERSON], [PERSON] et al. [9] studied the effects of various factors such as working pressure, precompression ratio, chamfer, and thickness of wear-resistant rings on the sealing performance of static sealing structures. [PERSON], [PERSON] et al. [10] developed a physical-mathematical model to better understand the contact between the O-ring and the sealing surface, shedding light on the sealing and wear behavior of static sealing structures. [PERSON], [PERSON] et al. [11] derived an engineering equation for solving sealing performance, friction, and design issues of O-rings in static sealing structures. [PERSON], [PERSON] et al. [12] compared the sealing performance of rubber material O-rings with graphite powder filler O-rings in static sealing structures. The result shows that the addition of graphite powder effectively reduced the friction in static sealing structures. Furthermore, [PERSON], [PERSON] et al. [13] used a self-developed durability device to investigate the fracture behavior of O-rings in static sealing structures exposed to cyclic high-pressure hydrogen. Several scholars have conducted valuable research on the sealing performance and friction of non-O-ring seals within static sealing structures. For instance, [PERSON], [PERSON] et al. [14] investigated the sealing performance of a static sealing structure consisting of a rubber D-ring and a wedge ring. They made a comprehensive comparison between the sealing performance of the D-ring and the O-ring, analyzing crucial factors such as the wedge ring, hydrogen pressure, and expansion. Similarly, [PERSON], [PERSON] et al. [15] utilized finite element simulation to analyze the static sealing structure of a hydraulic system at work. Through their analysis, they obtained valuable insights into the changes in sealing performance of the lip seal under different working temperatures. Furthermore, [PERSON], [PERSON] et al. [16] focused on studying the sealing failure mechanism of static sealing structures in high-pressure and high-flow water valves. Their research involved a thorough analysis of the influence of pressure, surface friction coefficient, and other factors on the sealing performance of U-rings. [PERSON], [PERSON] et al. [17] proposed a butterfly rubber ring seal as a solution to address the issue of seal failure on the groove side of the rubber ring in static sealing structures, offering an innovative approach to improve sealing reliability. [PERSON], [PERSON] et al. [5] explored the effects of sealing pressure, motion speed, and ambient temperature on the sealing performance and friction of U-rings in static seal structures. [PERSON], [PERSON] et al. [18] conducted simulations of the complete process of the lip seal ring, and effectively analyzed the sealing performance of the static seal structure in the whole working process. Scholars have conducted significant research on the sealing performance, friction, and surface wear of O-rings in dynamic sealing structures. For example, [PERSON], [PERSON] et al. [19] investigated the effects of pre-compression, fluid pressure, and coefficient of friction on the sealing performance of O-rings in dynamic seal structures. In another study, [PERSON], [PERSON] et al. [20] conducted reciprocating sealing experiments on a dynamic seal structure using a reciprocating sealing test rig. They measured the surface morphology and surface wear of O-rings before and after the tests using an electron microscope.
