Analysis of mechanical resistance of underrun protection of trucks.

Client: Metalurgica Belgrano

Regulatory changes allow the maximum load carried by a trailer to be expanded.

The company needed to determine the ability of the underrun protection design to pass the test described in regulation No. 58 (CEPE).

The numerical modeling tools were used as verification support, allowing to computationally test the static load state specified in the regulations.

Project include:

Reproduction of laboratory load test by FEA analysis.

Numerical calculation of stress and strain under elesto-plastic regime.

Design modification in order to increase underrun protection resistance.
