Simulation and Analysis of Defect Distribution in Passenger Car Tire under Dynamic Loading

Abstract

The paper deals with experimental simulation measuring and the analysis of defect distribution in passenger car tire under dynamic loading. The main reason for detection of defect extension is to recognize an influence of closed air, small bubbles, separations in tire and it is mainly connected with its quality during its service in a vehicle in terms of road safety. This analysis should help constructors to solve critical conditions in tire casing, whether material selection and individual components proportions are suitable and fit or even the whole construction of tire casing is suitable. The reason for detection of internal defects in tire casing is to avoid the wear of those tires which already contain some internal defects and already recognised separations, which could propagate during the movement of vehicles. This is closely connected with the occurrence of tire destruction and the main purpose is to prevent its critical status and later vehicle crash and human life menace.

Probability analysis of dynamical effects of axial piston hydraulic motor

“…For these estimates, the input distribution used plays a significant role. Knowing these distributions may, however, require analysis and regular control of the stability of the production process, which may not be a simple and inexpensive matter [9][10][11][12][13][14][15]. If we use the initial estimate to determine the probability of a even distribution of input values, then it is a pessimistic estimate.…”

Dynamic and Stress Analysis of a Locking Mechanism in the Ansys Workbench Software Environment

“…Explicit dynamic analysis in the ANSYS Workbench software environment was conducted to determine the stress-deformation and kine-matic behaviour of the mechanism with consideration of elastic-plastic behaviour of individual parts of the mechanism [2,8]. This type of analysis is characterised by very small time increments [7].…”

Contribution to fatigue damage prediction of thin shell finite element models

“…In our case the rainflow analysis for random stresses known in classic uniaxial form as von Mises or Tresca hypotheses is impossible. It means that the important goal of this part will be to propose some approaches to estimate the high-cycle fatigue damage for multiaxial stresses caused by random vibration analysed structure [10,16,17]. Generally we can apply two fundamental approaches for multiaxial rainflow counting:  Critical Plane Approach (CPA) [13], and  Integral Approach (IA) [10].…”
