- The description of the scheme and design of the test bench for testing vibration isolators intended for use in the vehicle's cabin suspension. Test bench construction allows to implement a wide range of loadings on vibration isolator of the vehicle cabin, to investigate the impact of the loading's arm changing and to perform analysis of the vibration isolator’s elastic and damping characteristics changing impact on cushioning quality. Variant of the test bench construction modernization, which can allow applying typical exploitation loads, which include vertical and lateral components, is described. We propose a scheme of forced oscillations excitation system on the test bench by cam-eccentric mechanism. It includes a DC motor with stepless frequency regulation and with cams of different shape on its shaft, which affect the contact surface of the test bench's vertical H-beam of a rocker arm. We also propose a scheme of forced oscillations excitation system on the test bench by inertial exciter. It includes a DC motor with stepless frequency regulation with inertial vibration exciter on its shaft, which consists of a mass, placed eccentrically relative to the shaft axis. There are two variants of the test bench scheme – with the forced oscillations excitation device and without it.
