Numerical analysis of forage trailer supporting structure

The paper discusses issues of examination supporting structure of forage trailer. Tests were applied to supporting structure, lowered in order to adjust the height of mix feeding for younger cattle. Lowering obtained by spreading of supports caused increase of the structure effort and increase of stress exceeding acceptable values. The paper describes the manner of preparation of numerical model and results of tests performed with its application. Based upon the results modification of the structure in critical areas was proposed. Implementation of such modifications resulted in improvement of effort of forage trailer supporting structure.
