MEASUREMENT OF FORCE DURING THE PULSE DEFORMATION OF METALS,
Abstract
Ram impact machines were developed for testing materials with impact tension, shear, upsetting, and cutting. The machines make it possible to measure: deformation time, the mean deformation rate, the time-deformation dependences, deformation load, pressure in the combustion chamber of the ram impact machine, and other dynamic stresses appearing in test specimens and in the elements of testing and working units and tools. The article describes the test method and a modernized electron-beam oscillograph of the OK-17M type employed for registration of stresses, pressures and elastic displacements appearing in test specimens and in individual components and parts of machines. Wire resistance-type sensing elements, glued onto specimens being tested or on an intermediate elastic element are used as sensors. The measured signals are photographically recorded on the oscillograph screen. The described apparatus can be recommended for research work in the field of high-speed testing and pressure working of metals, and also for measuring dynamic stresses appearing in machine parts, tools, and aircraft.
