BED INVESTIGATING DYNAMICS OF SUSPENSION OF VEHICLES Russian patent published in 1995 - IPC

FIELD: automobile and tractor transport. SUBSTANCE: bed investigating dynamics of suspension of vehicles has support platforms of front and rear axles, controlled D. C. voltage source, low frequency filter with unit of capacitors of variable capacitance, sinusoidal signal generator, two actuating mechanisms each composed of pulsator with electrically controlled hydraulic valve of proportional type with two windings, two converters of sinusoidal vibrations of suspension each integrating multivibrator, matching amplifier, capacitor, inductance coil connected in series. Inductance coil is entered by rod vertically attached to bottom of automobile. Bed also has detector, output resistor, element for extraction of sinusoidal components of vibrations of suspension, four converters of amplitude value of sinusoidal vibrations to D.C. voltage, two dividers each manufactured in the form of ratiometer with two windings. EFFECT: enhanced authenticity of testing. 6 dwg
