摘要：

The paper presents the concept of fatigue test stand designed for multiaxial tests. The main advantage of the test stand is the possibility to perform fatigue tests under any combination of bending and torsional moments - from constant amplitude loading with different loading frequency, phase shifts and amplitudes ratio to advanced tests under random loading with programmable stochastic dependence between loading components. The stand consists of two vibration shakers used as the source of the load being implemented on two separate levers. The levers are transferring the load in the form of bending moments to the experimental test sample. New designed control system of the stand with the use of the LabVIEW software was prepared. Currently the control of the test stand is at the stage of an open loop control. The preliminary tests have been performed with constant sinus loads. The paper also presents a finite element analysis of the maximum available stress for the test samples being used in the stand.
