  Observation of load transfer from fully mounted plough to tractor wheels by analysis of three point hitch forces during ploughing, Elsevier Science BV
  journal article in Web of Science
  During in-furrow ploughing the wheel running in the furrow exposes the soil to greater risk of undesired compaction of the subsoil. This fact is due to a different load placed on the rear axle wheels of the tractor. The wheel moving in the furrow is loaded more than the wheel moving on the land. This fact is also reflected in fuel consumption and performance. The aim of this paper was to analyse the possibility of eliminating the problem with different loads of the rear wheels by changing the length of the upper link of the three-point hitch. We also studied the impact of adjustments made on the economics of ploughing. During the experimental ploughing carried out for three lengths of the upper link, we have indirectly evaluated the load on the wheels. In the course of ploughing the exerted forces were measured by the strain gauge sensors attached to each link of the three-point hitch. These measured forces we used to calculate the load on individual tractor wheels using a verified algorithm that uses a multibody tractor model. The results show that the large difference between the loads on the left and right rear wheels typical for in-furrow ploughing can be reduced by adjusting the length of the upper link of three-point hitch from the original 5 kN-1 kN. Changing the wheel load resulted in reduction of fuel consumption per ploughed area by 13.7% and increased performance, namely the area ploughed per unit time, by 6.45%.

  The development of vehicles is constantly advancing, therefore, it is required to have more sophisticated tools for the development of a complete vehicle or its individual parts. This article describes modern tools used at the Institute of Automotive Engineering in Brno for vehicle development, i.e. simulation multibody software MSC ADAMS/Car or tools for MIL and HIL testing of mechatronic systems. Furthermore, the article presents tools enabling the use of multibody models for analysing data obtained from driving tests and software for processing and analysing the measured or calculated data obtained during all phases of vehicle development.

  The article presents optimization of kinematic performance of vehicle suspension. On the basis of demands on kinematic characteristics and on design process, a method suitable for optimization geometry of suspension in the stage before vehicle has been build. Also it is usable for tuning of handling behavior of vehicle during test procedures. An example shows subtasks that solve specific demands on suspension characteristics and algorithms of their combination for achievement of the final optimum.

  The paper presents possible benefits of using derivative-free filter to estimate vehicle dynamics states based on measured signals where the complexity of nonlinear dynamics limits the use of Extended Kalman Filter commonly used for nonlinear filtering. The filtration process was applied to real data obtained from testing manoeuvre. Bicycle model of a vehicle was used for state description and lateral dynamics investigation. Filter implementation in Matlab-Simulink software environment was used for analysis and comparison with earlier results.

  Today's automotive industry takes full advantage of CAD, multi-body, FEM and other software systems. Quality of simulations depends on the accuracy of input data. Software systems need to be provided with quality data and that's what 3D scanners can be used for. On the contrary, another large category of applications that can use 3D scanners is the control of outputs of various programs. Chapter describe utilization of optical Systems TRITOP - ATOS in vehicle dynamics.
