- Abstract
The development of any vehicle is always carried out under the condition of strict enforcement of certain, preset performance characteristics. A special place among them is occupied by the so-called running performance, which does not affect the assessment of the traction-dynamic parameters of the vehicle, its fuel economy, etc. The direction of our activity is the development of adaptive suspensions of vehicles of a new principle of action. Currently, a group of leading researchers of the Automobile and Tractor faculty of the South Ural State University has completed a large cycle of fundamental research work on the creation of adaptive suspensions of vehicles of a new principle of operation, allowing to adjust the performance of the suspension while the vehicle is moving, depending on road conditions, either in automatic mode or in manual control mode. We have developed, researched, designed, manufactured and tested the following main components of adaptive vehicle suspensions: adaptive, lockable shock absorbers and elastic elements with non-linear characteristics, which, in combination with their functional properties and performance characteristics, significantly exceed existing foreign analogues, not to mention domestic designs. To demonstrate these advantages, a full-scale stand of the chassis of the "right front quarter" of the VW PASSAT CC was created and comparative simulation tests of "moving the car over bumps" with a regular suspension and with a suspension equipped with elastic elements and adaptive shock absorbers of our structures were carried out. This paper analyzes the characteristics of the perspective adaptive shock absorber, in terms of use in the vehicle's suspension, with an ultra-wide range of performance adjustment. The article describes the stand and the results of comparative simulation, experimental studies of the dynamic characteristics of the "car" VW PASSAT CC with a standard suspension and with a suspension equipped with adaptive shock absorbers and elastic elements of our design.
