Development of a method for substantiation of the design and working parameters of a lever-electromagnetic stabilizer of lateral stability system for stabilization of the transverse stability of cargo vans

Abstract

The work is devoted to the issue of increasing the lateral stability, handling and safety of a car with a lever-electromagnetic system of transverse stabilization. The road safety of vehicles should improve with the rapid development of vehicle dynamics. Knowledge of vehicle roll stability data is important for the development of vehicle stability systems that will improve road safety. As a result of a review of trucks and passenger vehicles, it was found that the normal anti-roll bars are used to increase lateral stability. At present, higher-class passenger cars have begun to use active stabilizers (anti-roll bars), which provide more efficient alignment of the car when cornering. The main disadvantage of a conventional anti-roll bar is the reduction in suspension travel and does not provide the necessary smoothness when cornering and when maneuvering. These movements can lead to dangerous traffic situations. Thus, unfavorable driving conditions are manifested in terms of vehicle stability and controllability, as well as a smooth ride, which determines the level of comfort during heavy cornering and maneuvering. A new vehicle active safety system has been proposed, which makes it possible to increase lateral stability. The given method of substantiating the design and operating parameters of the lever-electromagnetic lateral stabilization system, which increase the lateral stability of light-duty vans, and the results of a study on the example of a GAZelle NEXT cargo van when cornering and maneuvering are given.
