Three-cylinder gasoline engines are increasingly favored by major automobile manufacturers due to their good fuel economy, low manufacturing cost and consumption. However, the inherent balance problem has an adverse effect on vibration of whole engine even comfort vehicle, which limits its application in high-end models. This paper studied dynamics characteristic flexible multi-body system thre...

Ah&r&--In this paper, we study the problems of radial diffusion of a fluid through a hollow non-linearly elastic orthotropic cylinder. It is found that shearing and stretching have qualitatively different effects on the diifusion process. The effect of orthotropy on the difision process is also studied. These results are compared with those for the isotropic case [cf. Znr. 1. Engng Sci. 25, 144...

In this paper ,the general solution of steady-state one dimensional asymmetric thermal stresses and electrical and mechanical displacements of a hollow cylinder made of functionally graded material and piezoelectric layers is developed .The material properties ,except the Poisson's ration, are assumed to depend on the variable radius and they are expressed as power functions of radius. The temp...

In this paper, the general solution of steady-state two-dimensional non-axisymmetric mechanical and thermal stresses and mechanical displacements of a hollow thick cylinder made of fluid-saturated functionally graded porous material (FGPM) is presented. The general form of thermal and mechanical boundary conditions is considered on the inside and outside surfaces. A direct method is used to sol...

The article shows the effect of torsional rigidity of beam elements onto spatial work of bridges, floorings and other plate-ribbed systems It is shown that, in determining the torsional rigidity using existing methods it is necessary to have spatial spiral cracks, but torsional rigidity when normal cracks is not researched. A method is described for determining the torsional rigidity of reinfor...
