While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.
而钝头拱形细长体在大迎角下的截面侧向力分布与脉冲起动横流比拟方法预测的侧向力曲线的形状是基本相同的,而且随着滚转角旋转360°,截面侧向力分布曲线的特征点和半周期基本保持不变,即它们都基本上不受滚转角变化的影响;但是截面侧向力分布曲线极值点形成的原因却是不同的,这是细长体绕流区别于二维圆柱绕流的一个重要特性。

Then the paper deduced the quench development characteristic of MgB2 tape by all the above study. The work environment cooled by GM cooler is an adiabatic environment. However the environment cooled by liquid helium is incomplete an adiabatic environment. In order to simulate the adiabatic environment, the tape was remodeled as follows. The tape is bundled by vitreous riband in half pile mode, and the angle of the tape and the riband is 45 degree. Then use cryogenic epoxy hardener to coat the surface of the riband.

Pass to count to Wisterch parameter , and the steel wire is different from the molding tool get in touch with the length, and settle the path the research taking the length work the stabber angle to get under differently pull to stir the term, mold core adoption of best severally why size, combine the best work stabber of research the Cape, and settle the path to take the length nextly steel wire is in the molding tool of have fever to measure, air inside dispel-heat calories, winding dispel-heat on the coil-canister , and its molding tool dispel-heat calories of, and cause the steel wire the temperature difference pass in and outing the molding tool to influence steel wire machine function, under the experiment inside pull to stir the term according to the same race different work stabber Cape half of adoption the Cape(7 degree,10 degree,12 degrees, the best mold Cape, experience mold Cape) settle the path to take the length(2-3 mm,3-4 mm,4-5 mms, theories length, experience length) to proceed to experiment, and get the conclusion, work stabber the Cape then is more big the steel wire get in touch with the length with
通过对Wisterch参数,钢丝与模具接触长度、定径带长度、工作锥角度的研究得到了在不同拉拨条件下模芯采用的最佳几何尺寸,并研究最佳工作锥角、定径带长度下钢丝在模具中的发热量、空气中散热量、卷筒上的散热量及其模具散热量的不同,导致钢丝进出模具的温度差别对钢丝机械性能的影响,在实验中根据同种拉拨条件下采用不同工作锥角半角、定径带长度进行试验,得出结论,工作锥角越大则钢丝与模具接触长度越短,钢丝变形越剧烈,在模具中发热量就越高,导致钢丝出模温度高,使钢丝强度、硬度升高,弯曲、扭转次数降低,并且降低模具使用寿命。在其它条件相同的情况下,定径带越长则钢丝与定径带简壁磨擦增大,使钢丝发热量加大,从而使钢丝强度、硬度略升高,弯曲扭转次数略降低但定径带的增大减小了钢丝变形产生的弹性后效使钢丝出模直径比较稳定。

A new mathematical model is put forward numerically to simulate the wheel ovalization.. In the numerical simulation, the dynamic model of a half railway vehicle coupled with a tangent track is employed. Using the new numerical method investigates vehicle-track coupling system dynamic responses including lateral and vertical displacement of wheelsets and the vehicle, lateral and vertical vibration acceleration of the track at different phase angle of the two side wheels of the same wheelset, which are compared with that of the traditional model. The numerical results show that the discipline and frequency of dynamic responses are accordant, amplitude and phase of lateral dynamic responses are different. It is concluded the traditional track geometric irregularity excitation model does not simulate the effect of periodic wheels ovalization on vehicle-track coupling system dynamic behavior truly, the new model is more accurate and reasonable.
本文研究了车轮二阶周期性非圆化—椭圆化,建立了一个新的模拟车轮椭圆化的数学模型,结合车辆-轨道空间耦合动力学模型,计算了同一轮对左右车轮不同相位和车轮椭圆度下轮对和车体的横、垂向位移,钢轨横、垂向振动加速度,并与传统模型计算结果作了对比,分析表明两种模型的动力响应变化规律和频率一致,但横向动力响应幅值和相位均存在不同程度不可忽略的差异,因此传统的轨道几何不平顺激励模型不能真实模拟车轮的周期性椭圆化对车辆-轨道耦合动态行为的影响,而本文模型更能反映实际椭圆车轮与钢轨接触情形,计算方法准确而合理。
