This engineering note documents the testing of the EC hydraulic drive cylinder. The test was done to insure that the cylinder could operate at the desired compression. The purpose of the test was to determine the deflection of the cylinder rod at a pressure of 7000 psi. This note includes an explanation of the procedure used and a summary of the result of the testing done on May 1, 1991 by Gary Trotter. The purpose for load testing the cylinder was to insure that it could operate at the pressures required. These pressures were calculated in EN 254, with the appropriate safety factors included. Another engineering note to refer to is note 3740.510-EN-298, which explains the testing of the cylinder relief valve, and the effect of the difference in cross-sectional areas on the forces involved. The general result of this load test was that the cylinder could operate safely at the design pressures. Since the rod was tested in compression, calculations were required in order to determine the buckling force of the rod. The maximum cylinder test pressure was based on the allowable force on the rod for elastic buckling. This force was calculated using two methods, a simple Euler column calculation, and an AISC method.
