Technical Feasibility of Deceit While a Vehicle is Weighed in Motion with a Very Low Speed

The study concerns the problem of overloading vehicles driven on public roads. gross vehicle mass and individual axle loads are limited by legal regulations. However, a tricking method, applicable to most popular designs motor multiaxial tractor-semitrailer units, has been shown that weighing inspectors, even if provided with precise scales, may be deceived without any interference in scale operation. In such current state changed modifying stiffness pneumatic suspension springs, which is now technically feasible. author used two authorial models simulation program. Calculation results obtained for four-axle five-axle unit, taken as an example, have demonstrated. They show deceit possible when weighed motion very low speed.
