Comparative Analysis of Experimental and Numerical Evaluation of Strength of a Boom of the Underground Loader

The paper presents comparison of the results obtained from the numerical simulation and the experiment. A research subject was a boom of the loader designed for the underground mines. Strength analysis of the boom was carried out in the static range. The numerical calculation was performed using finite element method (FEM). The experiment was conducted with the use of the strain gauge half-bridges to validate the computational model. Measurements were taken during various actions of the loader. This contribution describes one of the calculated cases. After the results comparison, the appropriateness of the numerical simulation has been confirmed.
