摘要：Rail wear is one of the main reasons for reducing the service life of high-speed railway turnouts in China. The rail wear characteristics of high-speed railway turnouts are influenced by a large number of input parameters of the complex train-turnout system. To reproduce the actual operation conditions of railway turnouts, random distributions of these inputs need to be considered in rail wear simulation. For a given nominal layout of the high-speed railway turnout, 19 input parameters for rail wear simulation in high-speed railway turnouts are investigated based on orthogonal design of experiment. Three dynamic responses(wheel-rail friction work, normal contact force and size of contact patch) are defined as observed values and the significant factors(direction of passage, axle load, running speed, friction coefficient, and wheel and rail profiles) are determined by two unreplicated saturated factorial design methods, including the half-normal probability plot method and Dong 93 method. As part of the associated rail wear simulation, the influence of the wear models and the local elastic deformation on the rail wear was separately investigated. The calculation results for the wear models are quite different, especially for large creep mode. The local elastic deformation has a large effect on the sliding speed and rail wear and needs to be considered in the rail wear simulation.

摘要：It has been generally recognized that Green function integrated with Boundary Element Method (BEM) has advantages in dimensional reduction, high accuracy and satisfaction of the radiation condition at infinity, etc. Recently, the computational technique has rapidly developed and the orient-object programming has been widely applied, whereas the attribute of abstraction and the integration of Green function employed in BEM have not been discovered yet. In this work the abstraction and integration of Green function are carried out for soil dynamics problems, and the procedure of the object-oriented calculation method is presented. Based on the Green function developed for the two-phase saturated medium, the response of the wave field to tunnel subjected to dynamic loading is calculated, and the transient solution as well as the time history of response is obtained.

摘要：万花筒项目精神简介1、目前,万花筒项目处于理想化文化艺术产业阶段。2、文化艺术项目现今都挤进城里,已经塞车。我们现在乡村造个文化艺术的湿地。是地理会生出些什么种类,不可预知,有一点确可以肯定,一定会生出些五花八门的另类物种来。3、留了些鸟儿乐于拉屎的地方,给那些有乡绅情怀,正要逃离都市的艺术家们,自己按自己的意愿盖房种地,酿酒,并往＂湿地＂里撒滴水。
