This article discusses one of the component factors of energy consumption to overcome obstacles car threshold (curb- fencing) in determining the speed of vehicles after an accident on the basis of the law of conservation of energy. This factor is associated with the energy compression of the shock absorber wheel contact with the threshold. The studies were performed on the example of twin-tube hydraulic shock absorbers VAZ 2101 ... 07, on the basis of the test center of St. Petersburg factory shock absorber «Plaza» with attorneys established order stands. According to the results of bench tests damper build business chart coordinates «piston stroke → drag force on the rebound (compression)» , as well as the characteristics of the shock absorber resistance in coordinates «Vp- Fotb,cx». The data obtained were determined resistance characteristics of energy consumption shocks on the compression stroke. The proposed technique allows for an analytical study on the energy costs of suspension on the compression stroke to its breakdown.
