Abstract: | This type of tests have been performed in order to determine the resistance to rupture of a 20 HP tractor draw bar, after running a number of 2.000.000 cycles, in an accelerated rate, at amplitudes and frequencies established according to D 89/173/CEE. It has also been checked whether this type of bar ensures the mobility range required by the Directive, finally finding if there occurred any fractures, permanent deformations or visible exterior deteriorations. |
