查询词典 voltage barrier

Based on the ETA/VPG and LS-DYNA software platform and "vehicle-barrier-curve-road" integrated system dynamics model, in the research, the orthogonal experimental design method and the dynamic explicit finite element method were applied jointedly. The rear wheel elevation was considered as criterion for evaluation and six cross-sectional shape design variables were created. The application of L25 (5^6) orthogonal table for simulation and the use of SPSS statistical package help the variance analysis of simulation results, and the influence levels of various factors were studied to determine the optimal parameters of concrete barrier.

为此，以NJ型混凝土护栏尺寸参数为参考基础，以防撞等级为SS级的护栏为研究目标，以大型客车总质量为18t、碰撞速度为80km/h、碰撞角度为20°的碰撞条件为研究工况，基于eta/VPG及Ls-dyna软件平台及&汽车－护栏－弯道&一体化车－路系统动力学模型，联合应用正交试验设计方法及动态显式有限元方法，以客车后轮抬高量为考核指标，对控制弯道混凝土护栏截面形状的6个设计变量，应用L25(5^6)正交试验表安排仿真试验，借助SPSS统计软件包，对仿真试验结果进行了方差分析，找出了各因素对结果的影响程度，并据此确定了弯道混凝土护栏的最佳尺寸参数。

绿色贸易壁垒是在20世纪80年代兴起的一种非关税壁垒形式，其表现形式是进口国通过严格的环保标准和其他措施，阻碍国外商品进入本国市场，构成实质性的贸易障碍。发展中国家由于经济及生产技术水平较低，容易受到其制约或限制，因而引发贸易争端。WTO争端解决机制所具有的严密的程序性、较高的透明度和公平性，将有助于发展中国家突破绿色贸易壁垒。当然，这种积极性作用也因WTO争端解决机制本身的某些缺陷而不能完全发挥。
