Abstract

The relevance is substantiated and the impact of taking into account the malleability of model elements on the resulting dynamic loads is evaluated. The solution of the problem is presented by the example of a dynamic model of a 14.5-ton front loader with a load-bearing system with rigidly fixed wheel movers to the front half frame and a swinging bridge on the rear half frame. This method of fastening allows us to assess the effect of the pliability of the elements of the AF by comparing the vertical reactions that occur in the contact spot of the wheels with the support surface. The dynamics models are made in the NX 2206 software package NX Motion application. The comparison of vertical loads arising on wheel propellers in given load conditions (symmetrical and skew-symmetric) using absolutely rigid and malleable models of the load-bearing system is carried out. It is found that the loads for skew-symmetric loading modes can differ by up to 20% depending on the rigidity of the frame.
