| Summary: | The paper applies to the issue of preservation of passenger vehicles during overcoming the roadblocks on a dry asphalt surface with the constant speed. The study aimed to estimate the forces which are affecting the suspension of the vehicle during the contact between a tyre and roadblock. Using the video recording it is possible to calculate the values of the tyre deflection and forces acting in the system. The obtained deflections of the tyres were compared to earlier laboratory test results and load-deflection characteristics of the tyres with the same size. The roadblock with the defined geometry causes a dynamic deflection of the tyre. During the study a significant change in the geometry of the suspension has not occurred. The paper presents the characteristics of the vehicles research with a particular regard to model and type of tyres. The determination of the exact dimensions of the roadblocks and application of the ADIS 16385 system for acquisition and archiving the features of the kinematic motion of the vehicle allowed to determine the speed at the moment of collision with the roadblock. |
