The article deals with recent failures of the EUSAMA methodology which is used for non-destructive testing of the car chassis without disassembling. Using simulated data, we perform an analysis of false-negative evaluation of car condition which occurs often on cars, which are actually in good technical shape. Suggested analysis is able to evaluate the changes introduced to the testing methodology...
This paper tries to find the reasons of differences between results from semiactive suspension simulations and from real measurements. Simulations of semiactive algorithms which have already been published in many scientific papers have showned a great potential for improvement of the suspension quality. However, experiments with suspension controlled by semiactive algorithms which are supposed to...
The article describes the original design of a slit flow rheometer. The behavioral 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...
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...
