Abstract

The re-design at the front-head/guide-bearing interface of a linear pneumatic actuator is proposed in this paper. Design changes were performed by means of finite element analyses. Contact pressure and its redistribution at the rod-guide interface were assumed to be the “leading parameter” in this process to promote improvements of tribological behaviour,viz.,reduction of guide-bearing wear and increase of cylinder life. Wear measurements and life tests made possible a comparison of pneumatic actuator life: these were modified on the basis of the various re-design solutions proposed. Therefore, a validation of the model's predicted conditions was possible.
