Investigation of the experimental car body in static bending and torsion / ; Statiškai lenkiamo ir sukamo eksperimentinio automobilio kėbulo tyrimas.
During the study conducted a simplified numeri-cal model of the body structure of an experimental car has been developed, dangerous points of the load-body struc-ture have been determined. The formalizing process of the numerical model was discussed in the paper, data of frame stiffness and data of displacement of typical points ob-tained by numerical and experimental methods have been compared. After a car body experimental static bending and static torsion testing it was defined that deflection of load-body structure in car base is equal to 1.58 mm. Dur-ing diagonal torsion testing of load-body structure at the torque of 3789 Nm the load-body structure twists till 0.93 degree. When calculating for static bending, difference between the results provided by different models is about 2 times. In case of static torsion difference between the re-sults obtained with different models is about 1.27 times.
