ANALYSIS AND DESIGN OF CUSHIONING IN HYDRAULIC CYLINDERS.

Abstract

Hydraulic cylinders, when used to drive heavy loads at high velocities, need to be decelerated or cushioned at the ends of the stroke in order to prevent damage. In this paper, one of the methods of cushioning, namely, the annular clearance method of cushioning is analysed and based on the results of the analysis, a suitable procedure for the design of the cylinder is suggested. An example is worked out to illustrate the design procedure.
