Study Results

By using the geometry modeling software Pro/E, the three-dimensional model of hydraulic shield support has been built. Considering of the loading conditions and displacement constraints which the hydraulic shield support suffers from under the actual working conditions, the static strength and fatigue strength of the hydraulic shield support were analyzed by FEM when they were in two different typical working conditions of the support height, and the weakest part which was discovered in the analysis was improved in its structure. The study results showed that the designed hydraulic shield support could meet the requests of the static strength and fatigue strength. The column of the hydraulic shield support and the ear plate which locates in the connection area of the column and the push beam are the weakest parts. The counterforce given by the ground mainly focuses on the mid-back position of the hydraulic shield support, which meets the requirements of saving labor when they were removed. In the Finite Element Analysis when the reinforcement ribs were added to the ear plate, we found that the maximum equivalent stress is reduced by 150 MPa and the fatigue life coefficient is reduced markedly as well. The possibility of the fatigue breakage was decreased largely after the structure was modified and the service life of the hydraulic shield support was improved. These prove that the improvement of the hydraulic shield support structure is reasonable and feasible.

Abstract It is a challenging task in the design of automobile tires to predict lifetime and performance on the basis of numerical simulations. Several factors have to be taken into account to correctly estimate the aging behavior. This paper focuses on oxygen reaction processes which, apart from mechanical and thermal aspects, effect the tire durability. The material parameters needed to describe the temperature-dependent oxygen diffusion and reaction processes are derived by means of the time–temperature–superposition principle from modulus profiling tests. These experiments are designed to examine the diffusion-limited oxidation (DLO) effect which occurs when accelerated aging tests are performed. For the cord-reinforced rubber composites, homogenization techniques are adopted to obtain effective material parameters (diffusivities and reaction constants). The selection and arrangement of rubber components influence the temperature distribution and the oxygen penetration depth which impact tire durability. The goal of this paper is to establish a finite element analysis based criterion to predict lifetime with respect to oxidative aging. The finite element analysis is carried out in three stages. First the heat generation rate distribution is calculated using a viscoelastic material model. Then the temperature distribution can be determined. In the third step we evaluate the oxygen distribution or rather the oxygen consumption rate, which is a measure for the tire lifetime. Thus, the aging behavior of different kinds of tires can be compared. Numerical examples show how diffusivities, reaction coefficients, and temperature influence the durability of different tire parts. It is found that due to the DLO effect, some interior parts may age slower even if the temperature is increased.
