FIELD: test equipment.
SUBSTANCE: invention is related to testing equipment. Stand contains a bed with stands, power hydrocylinder and control panel. On the stands in fastening elements a lower beam simulating unsprung mass, and an upper beam simulating sprung mass are installed. Both beams are installed with the ability to rotate relatively to their center. On the upper beam on both sides there are loads with the possibility of their movement relatively to the beam center. Upper beam is equipped with a sensor for angular and linear speeds and accelerations connected to the input of the current switch. On both sides at the ends of the beams brackets are mounted, between which are damping elements in the form of a rubber-cord shell, connected through a solenoid valve with a compressor installed on the bed. Power hydraulic cylinder rod is connected to the control panel, connected with the lower beam. On the upper beam in the attachment points of the suspension sensors that measure the vibration of the sprung mass are fixed. Between the bed and unsprung weight sensors of it relative movement to the frame are fixed. Signals from the sensors are fed to the signal amplifier, and from it to the spectrum analyzer of the input and output influences on the suspension system and then to the control panel.
EFFECT: achieving enlargement of functional capabilities of a stand.
