The method of the vehicle suspension system damping element load characteristic synthesizing

Abstract

BACKGROUND: Nowadays the problem of improving the ride smoothness of vehicles is relevant. The main way of solution is to carry out synthesis of design parameters of suspensions. To carry out such works and to obtain the most satisfactory properties, the new methods of synthesis of load curves of vehicle suspension devices are necessary.

AIM: Development of the new method of synthesizing the curves of a damper of the vehicle suspension.

METHODS: The study deals with the problem of controlling vibrations on their transfer paths by determining the required load curve of a vehicle suspension damper. Analytical methods and simulation modeling methods are applied in the solution process.

RESULTS: As a result of the study, the new method based on the building the range of permissible damping values and selection of the curve on its basis has been created. Based on the obtained method, a number of nonlinear curves of the damper of the primary system of vehicle suspension and selection of the most suitable one regarding to ride smoothness were formed.

CONCLUSION: As a result of the study, the new method of synthesizing the curves of the damper has been obtained. As a result of the comparative evaluation, the efficiency of the new method is confirmed. For the considered study object, the difference in ride smoothness is up to 25%.
