4. Conclusions This article shows the measurement process conducted on a prototype bus, aimed at gathering data for more precise strength analysis and responsible weight optimization. Accelerometer data from the bus body will be utilized to prepare basic fatigue assessments. Moreover, scanned roads, along with advanced software, nonlinear suspension element characteristics, and tire models, present an excellent opportunity for realistic drive simulations. Moving forward, the focus will be on numerical analysis and correlation with test results. While detailed results are kept confidential, more information can be obtained upon request.
