BED FOR TESTING VEHICLES Russian patent published in 1995 - IPC

FIELD: test equipment. SUBSTANCE: base for securing vehicle is manufactured mobile in horizontal and vertical planes by means of liquid support fabricated in the form of upper and lower horizontal plates interacting through layer of liquid. Upper smooth horizontal plates are made fast to mentioned base and lower plates are coupled to stationary jig of bed. in this case vehicle is tied up with wheel discs to modules simulating road loads through shaft of bearing unit (radial and butt bearings). Simulator of aerodynamic loads in the form of diffuser with built-in fan in mounted on tracks on edge of bed embracing mobile base of vehicle. Base provides during movement on liquid support for inertial loads on vehicle in horizontal plane of any specified direction with wide spectrum of character of growth of these loads. By switching on independent modules loads originating from bossy road or its concavities, from unflatness and isolated bulges and pot holes and simulation of rod effects on vehicle are reconstructed. With cutting in diffuser air flow will circumflow vehicle in any direction of angle of attack relative to body of vehicle. EFFECT: enhanced authenticity of simulation of loads effecting vehicle during movement. 2 cl, 5 dwg
