Research and Testing Complex for Analysis of Vehicle Suspension Units

Volgograd State Technical University (Russia) has collaborated with BISS-ITW (India) and Test Rigs (Russia) to develop a unique research and testing servo-hydraulic complex designed to study various vehicles suspension units to determine their elastic-damping characteristics and vibration isolation properties. Bench equipment allows to test individual suspension components (hydraulic and gas-filled shock absorbers, coil springs, leaf springs, shock absorber struts, pneumatic and hydro-pneumatic springs, wheels and tires, bushings) and the single support suspension unit as an assembly with sprung mass corresponding to the real load on the wheel. The test program set the operating modes of the suspension units at the kinematic and force excitation using servo-hydraulic equipment that is controlled by a special software suit. The capabilities of the test rig allow to obtain the real characteristics of the tested suspension system elements and a comprehensive assessment of their efficiency in the modes which are typical for operating conditions of the vehicle suspension.
