Abstract
Изобретение относитс к испытательной технике, в частности к установкам до испытани образцов на усталость при изгибе с кручением. Цель изобретени - повьшение точности за счет создани статических составл ющих одним силовым фактором, а также расширение видов прикладываемых нагрузок за счет обеспечени бигармонического нагружени . Образец 11 устанавливают в захваты 1,2 параллельно ос м вало 9 6 дебалансных вибровозбудителей. При вращении с различной угловой скоростью валов с инерционными массами 7 и 8 происходит нагружение образца циклическим ангармоническим изгибом с кручением. При повороте рычага 20 измен етс асимметри цикла. Фиксаци положени рычага 20 упором 24 реализует жесткое нагружение, а нагружение рычага 20 с помощью подвески 22 с грузом - м гкое, 1 з,п. ф-лы, 2 ил. (О (ЛThe invention relates to a test apparatus, in particular, to installations prior to testing fatigue specimens for bending with torsion. The purpose of the invention is to increase accuracy by creating static components with one force factor, as well as expanding the types of applied loads by providing biharmonic loading. Sample 11 is installed in grips 1.2 parallel to the axis of 9 6 unbalance exciters. During rotation with different angular velocity of the shafts with inertial masses 7 and 8, the sample is loaded with cyclic anharmonic bending with torsion. Turning the lever 20 changes the cycle asymmetry. Fixing the position of the lever 20 by the stop 24 realizes loading, and the loading of the lever 20 by means of the suspension 22 with a load is soft, 1 s, n. f-ly, 2 ill. (Oh (L
