  The article describes the original design of a slit flow rheometer. The behavioural problems of MR fluids and the main deviation from the commonly introduced Bingham model, which describes the MR fluid, are explained at the beginning of this article. Furthermore, the usual operating parameters of the MR fluids and devices are defined, such as: shear rate, viscosity in the off-state, yield stress, their dependence on temperature and the expected life of the filling. In the absence of a suitable rheometer a new design of rheometer was proposed, which allows long-term testing of MR fluids under real loading conditions. This article describes the important details of the construction. Particular attention is devoted to temperature measurement, calibration of the rheometer and data analysis, including mathematical tools and statistical evaluation of a set of measured points.

  This article is concerned with capabilities of analysis of a chaotic behavior of the stub-shaft sleeve bearing inside the automotive differential. Analytical methods based on phase-trajectory diagrams and fractal dimensions are used. Effect of the chaotic behavior on automotive differential noise is examined as well. The purpose of the article is to give an overview of practical use of the above mentioned methods. The potential advantages, disadvantages are discussed as well as expected contributions of application of the bifurcation analysis to solving the automotive differential journal bearing noise problem.

  This article describes a technique for the differential bearings noise reduction. Noise results from the mechanical looseness of the differential gear and connected elements and it is activated by the vibrations of the engine. A test rig for simulation of the phenomenon outside vehicle has been designed and behavior of the differential bearing has been analyzed. Analytical software that is capable to classify the types of the noise has been created. The mathematical model enables estimation of suitable range of differential bearings radial stiffness. Finally, the selected solution is tested on the test rig, thus the technique is verified.
