This report describes the development and testing of the 155 mm Ballistic Simulator for laboratory testing of artillery fuzes. Present test methods using a 5 inch air gun are compared with the ballistic shock environment and are shown to have significant limitations. The design approach of the new simulator is described. The new system includes as its basic component a 155 mm field gun and uses compressed air as the high pressure fluid. Provision for shaping the acceleration-time history is included as well as simultaneous rotation of the test item. Initial tests on the 155 mm Ballistic Simulator have been performed up to 12,000 gs and sample acceleration-time histories are shown. It is concluded that within its operating range, the new simulator provides a significantly better simulation of ballistic shock than the present test method.
