Inertial force-loading apparatus for simultaneous endurance testing of a large number of specimens and structural elements under simple, compound, and variable loading is described. The apparatus, developed for designing airframes, employs a biharmonic vibroplatform with a program mechanism for varying vibration amplitude and frequency and a four-rail trolley. The accumulation of fatigue damage is determined by 'statistical indicators'. The indicators are calibrated under laboratory and flight conditions. When installed on aircraft, they make it possible to establish statistical equivalents between the damage of 'indicator' specimens and the airframe elements of the aircraft being tested. (Author)
