Analysis on Sealing Performance for a New Type of Rubber Olecranon‐Shaped Sealing Ring in Pipe Jacking Joint

“…Given the complex nonlinear contact between the rubber rings and the pipe spigots/ sockets during installation, plus the material nonlinearity of rubber materials, the research on the joint sealing design for long-distance large-sectional rock pipe jacking construction is immature. In this context, this study creates the numerical mechanical model of rubber rings via ADINA software after consulting the analytical approaches and research ideas from similar extant studies, with which the stress variations of rubber rings before and after pipe joint installation are discussed, and the sealing performance verification and evaluation are carried out [14].…”

Reliability analysis and verification of the rubber support base for battery pack

“…The battery pack rubber support base is a support mechanism used for support and vibration reduction to ensure the reliability of the battery pack itself under vibration and impact environment. The support base is mainly composed of a ball stud and a rubber cover ball bowl, in which the internal lubrication protection part can be isolated from the external environment without interfering with the free movement of the ball [1][2][3][4][5][6]. The common failure mode of the ball stud is abnormal wear of the ball joint and the ball bowl, and most of the reasons for this failure are the invasion of dust and foreign matter after the rubber dust cover damaged.…”
