2.The magneto-elastic motion equation and the electrodynamic equation of the thin strip conductive plate in a leaning magnetic field are derived on the basis of the principle magneto-elastic theory, and the characteristic equations of the vibration of the plate supported along two long sides are obtained as well.
3.Pore deformation of low-permeability gas reservoirs is characteristic of elastic plastic deformation.
4.In this way, corresponding to every single transversely isotropic elastic random medium model, we can calculate and gained 15 different wave field characteristic quantities.
5.Via the forward modeling in the 2-D transversely isotropic elastic random medium, we studied the change features of the wave field characteristic quantities as changing the medias autocorrelation length and anisotropic coefficient.
6.Abstract: Suppose we view a locomotive as a whole system,the space configuration of each locomotive is described by a 17-freedomed in horizon surface.Taking into account the elastic supporting of first and second system,hanging equipment and resistance characteristic,a space vibration model of four-axis bogie vehicle crawl vibration is presented.The characteristic root of the model is calculated.The stability of vehicle crawl vibration and critical velocity is researched.The result is that increasing vertical and horizontal stiffness and resistance of every wheel can decrease crawl vibration of bogies and carriages.And the optimization parameters are given.The improvements lie in using electromagnetic or crawl vibration absorber to replace hydraulic pressure vibration one and using awl spring to replace old pillar one.
7.it has the characteristic of elastic deformation and its stress-strain curve basically meets hyperbola model ( Duncan-Chang) and;
8.This paper introduces the experience of students independent learning physical experiments on the opening days of The Experiment Teaching Demonstration Centre on vacation, and discusses the characteristic and effect of the elastic-study system.
9.Based on the tests of multi-ribbed composite wallboard, the characteristic of wallboard under different loading states have been analyzed in this paper, the corresponding mechanics computational models have been proposed, the multi-ribbed composite wallboards have been equivalent to uniform silicate wallboards, the practical calculated formulation on elastic-stiffness of multi-ribbed composite wallboard has been proposed, the calculation results accord ell with the tests results, so that the proposed formulation can be used in practice.
10.The dynamic force-displacement relation curve is of crucial important to the design and operation of mechanical impact devices.Using one-dimensional wave mechanics and characteristic line theory, this paper presents a testing method for determination of dynamic force-displacement relation curve from one-point strain measurement on an elastic rod endface.The principle of measurement, data processing method and experimental results for penetration into granite are discussed.4figs.,5refs.
