1) critical speed of vehicle
共振临界车速
2) resonant speed
共振转速，临界转速
4) critical speed
临界车速
1.
In order to obtain critical speed when articutaled-frame vehicles(AFV) drive stability, the driving stability of AFV with hydraulic steering system moving along a straight or a small curvature road was studied.
为了获得车辆稳定行驶的临界车速,对铰接式车辆沿直线或大曲率半径曲线行驶时的稳定性进行了研究。
2.
A roots-locating numerical method was used to identify critical speed.
应用一种数值寻根法分析了系统的临界车速。
5) critical failure vibration velocity
临界破坏振速
6) flutter critical wind speed
颤振临界风速
1.
The results show that the flutter critical wind speed can be significantly increased by mounting an upper central stabilizing barrier on the top surface of the upper chords of the transverse frames of the truss girder,and the flutter .
结果表明,在桁架加劲梁横梁上弦杆上侧设置适当高度的上中央稳定板可以较大幅度地提高桥梁的颤振临界风速,并且在常规的稳定板高度范围,颤振临界风速基本上随上稳定板高度的增加而提高;在横梁上弦杆下侧的主桁架内设置适当高度的下中央稳定板也能在一定程度上改善桥梁颤振稳定性,但效果明显不如上稳定板,在某些高度情况下甚至会降低桥梁的颤振临界风速。
2.
The variation pattern between flutter critical wind speed of bridge with flat box deck and wind yaw angle is significantly affected by wind attack angle.
扁平箱形截面桥梁的颤振临界风速与风偏角的关系明显地受到风攻角的影响。
3.
Thus the flutter critical wind speeds are much lower and the bridge is more unstable during this period.
尤其是在施工初期 ,结构的刚度比成桥要低得多 ,使得颤振临界风速最低 ,更容易发散 。
