Abstract: This article studies the torsional stiffness and fatigue characteristics of rubber air springs. Firstly,
an in-depth analysis was conducted on the structure and related standards of air springs. On this basis, a
new type of air spring torsion pendulum test device is designed and compared with the existing test device.
Through a new experimental device, the influence of different horizontal shear displacements and vertical
loads on torsional performance, as well as the influence of different loading cycles on fatigue performance,
were mainly explored. The research results indicate that the structural design of the new experimental device
is reasonable and fully meets the requirements of the air spring torsion pendulum test. As the horizontal shear
displacement increases, the torsional stiffness shows a decreasing trend, while the effect of vertical load
on torsional stiffness is not significant. This research provides theoretical guidance for the development and
testing of air springs.
Key words: air spring; torsional performance; experimental study
