نویسندگان
چکیده
This study concerns dynamic loading on the carrying structure of a flat car with elastic-friction longitudinal beams. The authors built mathematical model including vertical displacements in symmetrically loaded four 1 CC containers. was solved MathCad software. It found that maximum accelerations were about 2.0 m/s2. Thus, obtained within allowable values. presents results computer modeling loads container and calculation made finite element method SolidWorks (CosmosWorks) Besides, defined numerical values these distribution fields relative to car. discordance between 7%. research may be useful for those who are concerned designing innovative rolling stock units improving operational efficiency stock.

Steady-state, elastic-plastic growth of slanted cracks in symmetrically loaded plates
Elastic and elastic-plastic results are obtained for a semi-infinite slanted through-crack propagating in a symmetrically loaded plate strip with the aim of providing theoretical background to commonly observed plate tearing behavior. Were it is not for the slant of the crack through the thickness of the plate, the problem would be mode I, but due to the slant the local conditions along the cra...

Quasi-static frictional contact problems for bodies of fairly general profile that can be represented as half planes can be solved using an extension of the methods of Ciavarella and Jäger. Here we consider the ta...
متن کاملDynamic Stability of Functionally Graded Beams with Piezoelectric Layers Located on a Continuous Elastic Foundation
This paper studies dynamic stability of functionally graded beams with piezoelectric layers subjected to periodic axial compressive load that is simply supported at both ends lies on a continuous elastic foundation. The Young’s modulus of beam is assumed to be graded continuously across the beam thickness. Applying the Hamilton’s principle, the governing dynamic equation is established. The eff...
متن کاملFlat Beams in the SLC*
The Stanford Linear Collider was designed to operate with round beams [ 11; horizontal and vertical emittance made equal hi the damping rings. The main motivation was to facilitate the optical matching through beam lines with strong coupling elements like the solenoid spin rotator magnets and the SLC ales. Tests in 1992 showed that ‘flat’ beams with a vertical to horizontal emittance ratio of a...
