英文: But a motor-car has more momentum, and the chances are that it would keep going at the critical speed
and influence the driver long enough to make him lose control altogether.
中文: 汽车动力更大，它可能继续以这种危险的速度前进，时间长到足够使司机受到影响并丧失自控能力。 更详细...
英文: The object for this study is the rotor-support system of a bigger transmission power aeroengine with engaged action of central bevel gears and Square Film Damper(SFD), critical speed
and natural frequency of transverse vibration and static unbalance respo
中文: 以某型传动功率较大的具有中央锥齿轮啮合作用和挤压油膜阻尼器的航空发动机转子支承系统为对象，采用弯扭耦合传递矩阵法计算临界转速、横向振动固有频率、稳态不平衡响应和初始弯曲响应。 更详细...
英文: The numerical simulations showed that the semi-active control strategies based on multiple MR dampers worked well for suppressing the flutter of an entire HAR wing with aileron and increased the flutter critical speed
中文: 果表明,半主动控制可以将大展弦比平直机翼的颤振临界速度提高 7.%。 更详细...
