Numerical calculation result illustrates that the first bending vibration mode of car body occurs near the frequency region where riding comfort is most affected. Consequently,it is important to suppress the vibration firstly.
数值分析结果表明:车体一阶弯曲自振频率接近人体振动敏感区域,为减小车体弹性振动,必须首先降低一阶弯曲振动。
The steam turbine-generator set has two types of shaft vibration, bending vibration and torsional vibration.
弯曲振动和扭转振动是汽轮发电机组轴系振动的两大类型。
