Název v původním jazyce

Experimental determination of eigenfrequency and stiffness of suspension of elastically embedded body – vehicle application

Popis výsledku v původním jazyce

The essential characteristics of a suspension are represented by the stiffness constants of the equivalent springs and the eigenfrequencies of the oscillating movements in reference to the main central inertia axes of a vehicle. The premise of the experimental determination of these characteristic is the knowledge ofthe gravity center position and the knowledge of the main central inertia moments of the vehicle frame. The vehicle frame performs the general spatial movement when the vehicle moves. An analysis of the frame movement generally arises from Euler’s equations which are commonly used for the description of the spherical movement. This solution is difficult and it can be simplified by applying the specific assumptions. The experimental investigation of the railway vehicles is performed in the special stand or by utilizing method “ride on wedges”. The eigenfrequencies solution and solution of the suspension stiffness are presented in the article. The solutions are applied on the railway and road vehicles with the simplifying conditions. The solution is verified on the twin axle vehicle. A new method which assessed the characteristics is described in the article.
