Optimisation of the mass of a truck frame is done in this paper using a computer program. The structure of the carrying frame completely satisfies the criteria of stresses and displacements. In the finite element used in the stress-displacements analysis, the deplanation as the seventh degree of freedom is taken into account. In this way, complex analysis is possible because the stress components of the bimoment are considered. The analytical model, which represents a space thin-walled frame, entirely is verified. Therefore it is recommended as a model for mass optimisation of a frame. Dynamic laboratory testing of the truck model with real frame design and the truck vehicle are done. The theoretical predictions are compared with experimentally obtained data showing good correlation. The truck moving is represented by a biaxial electric-hydraulic simulator with simulated vibration. The control signal is a displacement (acceleration) which is recorded on a magnetic tape during the field testing of the truck. Data acquisition of the experiments is done automatically by computer.
