Correlation Between Horizontal Acceleration Testing and Tilt Testing for Load Stability

Safe Load Testing Technologies

Transport simulation is the knowledge area which reproduces the effects of the transport hazards. The accelerations produced during transport affects the transported goods. The onboard acceleration effects could modify the load stability and it could become a risk on the road. Different techniques for transport simulation are used to evaluate the load stability subjected to those forces produced during distribution. Two of these techniques are the horizontal stability test and the tilt test. The horizontal stability test produces an acceleration trapezoidal transient equivalent to the transient recorded on transport vehicles on emergency braking situations, meanwhile the tilt test inclines the test sample using the gravity. The regulations from some countries, like U.S.A, Canada, European Union, New Zealand, Australia, and some others fix the minimum acceleration, in which a load should hold on to road transport for safety reasons. Enrique will share the requirements and boundary limits for a tilt test suitable to evaluate the stability of a unit load subjected to an emergency braking of a vehicle and the considerations that must be considered in the unit load to be analyzed and compare the results with the deformation obtained in a horizontal stability test.
