Abstract
The behaviour of a low friction elastomeric seal for piston in pneumatic
cylinders is investigated using a numerical model which takes the seal's
geometrical assembly conditions and operating pressure in cylinder chambers
into account. The model assumes plane strain because of the high ratio of
average seal diameter to radial extension. Seal material was characterized with
a special numerical/experimental procedure. The study made it possible to
determine contact pressures between seal and cylinder chamber in the absence
of tangential adhesion or friction forces.
1 Introduction
Pneumatic cylinder operation depends basically on the behaviour of the seals
on the moving piston/rod assembly. In
