For vehicles in crosswinds , with the increase of crosswind angle , static pressure and side force of the vehicle windward increase and reach maximums at crosswind of 90 degree , and then decrease when the angle of crosswind continues increasing 在侧风影响方面,随着侧风角度的增大,车辆迎风面的静压、侧向力先增大后减小,在车辆受到90o侧风时最大。
In order to resist the structure ' s lateral load and reduce the lateral displacement efficiently in the design of tall building structure , the engineers generally design the joint as so - called " rigid joint " 高层建筑钢结构设计中，为了能有效地抵抗结构的侧向荷载和降低结构在侧向荷载作用下所产生的水平位移，工程师们一般都将节点做成所谓的“刚节点” 。
The simulation and experiment result indicate that the dual pole tool weakens the electric field at the side wall of the machined hole and hence leads to the reduction of hole taper and the improvement of the machining accuracy 模拟计算和加工试验表明，辅助阳极可以显著减弱孔侧面间隙区域的电场强度，从而有效地抑制发生在侧壁的杂散腐蚀，减小孔锥度，提高加工精度。
Zhu , however , declined to confirm the report . " overseas listings are badly needed for saic to raise massive capital to achieve its bold expansion at home and abroad , " said zhang xin , an analyst with guotai jun an securities co ltd Js6122wh js6116wh系列卧铺客车在侧围设计上大胆创新，精心雕琢的银色弧线飘带向两侧无限延伸，在展示柔美外形的同时，又带给您很强的速度感。
Before departing he requested that it should be told to his dear son patsy that the other boot which he had been looking for was at present under the commode in the return room and that the pair should be sent to cullen s to be soled only as the heels were still good 告辞之前他要求转告他的爱子帕，说帕所要找的那只靴子目前在侧屋153的五斗柜底下。这双靴子的后跟还挺结实，只消送到卡伦鞋店去补一下靴底就成了。
Numerical calculations are performed by the standard k - model and dynamic mesh capability on vehicles being in crosswinds , running in tunnel , passing by and overtaking each other . their aerodynamic characteristics are analyzed and some different turbulence properties are obtained 本文对fluent进行二次开发,采用动网格技术及标准k -两方程湍流模型对类车体在侧风情况、穿越隧道及超车、交会过程进行三维非定常数值模拟,获得了规律性的认识。
Abstract : based on the theory of the structure dynamics , with the limited element sap5 programm as the calculating way , a calculatingway of the dynamics intenisity of the sieve " s lateral plate is put forward and the reason why this kind of oscillating sieve causes crcak on the lateral plate is analyzed 文摘:以结构力学理论为依据，以有限元sap5程序为计算手段，提出了一种直线振动筛侧板的动力学强度的计算方法，并分析了这类振动筛在侧板上产生裂纹的原因
The dual - time stepping method proposed by a . jameson is applied to improve time precision for unsteady flowfield computation . the three dimensional grid for projectile with lateral jets , especially body - fitted for lateral jets exit , is generated by improved traditional methods with projection and zonal method 在改进传统网格生成方法的基础上，结合投影映射、分区拼接技术生成了弹丸侧喷流场单一区域三维计算网格，在侧喷流喷口边界实现了网格贴体化。
In order to consider the nonlinear behavior of material , the stress - strain relationship of concrete filled steel - tube structure is introduced in the following research . the analysis result shows that the stability factor of the bridge deceased significantly when the nonlinear behavior of material is considered 此外，本文结合目前钢管混凝土构件力学特性的研究成果，在侧倾稳定性分析中引入了钢管混凝土构件的轴压本构关系，以考虑材料非线性对侧倾稳定的影响。
This paper refers the figures and dates of some missiles in domestic and foreign , builds the aerodynamic date , engineer and rudders mathematic model , analyses the phenomenon of side jet interaction with external flow , builds a side jet model with append factor which conforms to the actual situation , and founds nonlinear mathematic model of this missile 本文参考了国内外各型导弹的形状和数据,建立了导弹空气动力和力矩模型、发动机模型和作动器模型,并且研究了在侧喷直接力控制时,侧喷与外流场的干扰效应,建立了更加符合实际情况的带有附加增益的侧喷模型。
