Hydraulic drive of vibration stand for testing the robotic systems units by random vibration method

This paper reviews the development of hydraulic drive of vibration stand for testing the robotic systems units (technical products) for vibration resistance by random vibration method. The physical laboratory model was developed for studying the dynamic properties of a test stand which allows to realize smooth sweep excitation frequency f1 within the range of 8…56 Hz and detect resonant modes. The new design allows adequate simulation of vibration during transportation and using gapless narrow-band spectrum of random vibrations from power units. The stand allows to implement a large number of test modes that demonstrate the prospects of its application for testing technical products by random vibration method. (paper)
