Fig. 6. Testing of sandwich panels and their computational simulations.

3. Tests of bus bodywork segments Two body segment tests were performed: deformation test of the roof segment lightened by glued sandwich panels and deformation test of the front part of the body including the glued large windshield. In both cases, two test segments were available to assess the repeatability of the proposed tests and their results. In both cases, the diagonal quasi-static loading of the bus body segment was simulated physically (using an electro-hydraulic loading system) and computationally. In the first case, the force and displacement in the hydraulic load cylinder were measured. In the second case, the gradual destruction of the windshield was also scanned. 4. Conclusion All presented tests aimed to refine the basis for simulating a bus rollover simulation according to ECE 66 and EC 2001/85. A long-term project partner of the Regional Technological Institute, Vision Consulting Automotive, was involved in subsequent calculations. The foreign project partner, Solaris Bus & Coach, acted as an experienced consultant from practice during the preparation of this paper.
