SB12.01 Underrun protection

Project introduction

Our task was to verify the roadworthiness compliance of an underrun protection for an amphibious vehicle using finite element analysis, followed by revising the results with a 1:1 scale model under the supervision of experts from the Institute of Transportation Sciences.

Characteristics

  • Type: Amphibious passenger bus
  • Operating zone: Inland water, zone 3

Main dimensions

  • Length: 12.075 m
  • Width: 2.55 m
  • Displacement: 18 tons
  • Passenger capacity: 43 persons

Construction design

Welded aluminum structure

Performed main tasks

  • Design of underrun protection element tailored to the rear part of the amphibious vehicle
  • Strength and size optimization of underrun protection components
  • Structural analysis using finite element method considering forces during collisions
  • Examination of a 1:1 scale half model in accordance with regulatory requirements
  • Compilation of results and finalization of underrun protection plans
