Modification of the Elastomer Test Machine

Abstract

The machine has been designed and constructed with the funding provided by the U.S. Army - E.R.O. Office (London), Contract No. DAJA 45-85C- 0044. During the trial and testing of materials for tyre pads with this machine several difficulties were observed and it was agreed that the following modifications should be incorporated in the existing machine to improve its performance and usefulness. Synchronisation is achieved by installing a dummy cylinder with its magnetic piston coupled to the linear table. Linear movement of the table will then move this piston whereby its in built magnet will activate proximity switches set at any selected positions within range of travel. The two proximity switches will in turn control power to energise the solenoid operated pneumatic valves to lower/raise the press ram. Great Britain.
