Fjädrings- och dämpningsegenskaper hos enaxliga släpvangnar. (Spring and damping characteristics of single-axle trailers.)

The aim of the study is to show some possibilities to evaluate the spring and damping characteristics that are described on a single-axle trailer from a traffic-safety point of view. A computer program was developed, simulating movements and dynamic wheel loads for a single-axle trailer, when passing irregularities on the road surface.
