Abstract
BACKGROUND: Dynamic models are widely used for vehicle dynamics simulation. Increase of simulation accuracy is achieved with adding flexible bodies in a model, making problem solving more complicated. Therefore, assessment of influence of considering the flexibility of the front loader frame on the emerging loads in the multibody system becomes necessary.
AIM: Assessment of considering the flexibility of the front loader frame on the emerging loads in the multibody system becomes necessary.
METHODS: The solution of the problem is presented with the example of a multibody model of a 14.5-ton front loader (FL) with a frame coupled with wheel movers rigidly fixed to the front half-frame and a swinging axle at the rear half-frame. This method of coupling makes it possible to assess the effect of the flexibility of the elements of the FL by comparing the vertical forces that occur in the contact patch of the wheels with the support surface. The multibody models are built in the NX Motion application of the NX 2206 software package.
RESULTS: The comparison of vertical wheel forces in given load conditions (symmetrical and skew-symmetric) using absolutely rigid and flexible models of the frame is carried out. It is found that the forces for skew-symmetric loading modes can differ by up to 20% depending on the frame stiffness.
CONCLUSION: As a result of the conducted research, it can be stated that taking into account the suppleness of the load-bearing system of the vehicle significantly affects the results obtained in the process of modeling.
