In this research we conducted a sensitivity experimental study where we explored the dependency of the shear strain on the seismic properties of bearings, namely lead rubber bearing (LRB) and super high damping rubber bearing (SHDR). The factors studied were vertical pressure, temperature, shear modulus of the inner rubber (G value), loading frequency, and loading sequence. Six specimens were adopted, i.e., three LRBs and three SHDR bearings. A series of test plans were designed. The seismic characteristics of the bearings were captured through a cyclic loading test, which included post-yield stiffness, characteristic strength, area of a single cycle of the hysteretic loop, equivalent stiffness, and equivalent damping ratio. A whole analysis of variances was then conducted. At the same time, to explore certain phenomena caused by the factors, an extended discussion was carried out. Test results showed that the temperature is the most dominant feature, whereas the G value is the least contributing factor, with the effect of the loading frequency and the loading sequence found between these two. The increment of the post-yielded stiffness for LRB from 100% to 25% is a significant reduction from a low temperature to high one. The slope of the characteristic strength versus the shear strain for LRB under high temperature is larger than the one under low temperature.

Study Process

This article presents the results of experimental study of the influence of tire vertical load and tire internal pressure on tire cornering stiffness. The results have been obtained with a mobile tire tester which was developed at department “CEAET” at TU-SOFIA. The information about the dates of size load, index speed, index group, wearing out is obtained from Goodyear website, www.goodyear.eu. The study process concerns three main areas: (i) the choice of the experimental methodology; (ii) calculation and analysis of the data; (iii) discussion and conclusion. The obtained results give the possibility to determinate the role of tire on vehicle handling and stability.
