The article describes an engineering calculation method of vertical loads acting on the
vehicle when it runs on the road roughness. We obtained ratios between the heights of the
irregularities that cause equivalent loads when different wheels run on them. The interre-
lation between loads that occur when different wheels are hitting on the same road
roughness is established on the base of a linear model. Practical importance of the ob-
tained equations consists in a possibility to determine loads on a vehicle in various cases
based of the results of one test. Computational results can be used at the early vehicle
design stage in strength and durability calculations of bearing systems.
Keywords:
vehicle, loads, bearing system, mathematical models, analytical calculation.
