查询词典 damping-off

Based on the 1T15M-2 reversible sleeve air spring made by Firestone Corp., an air spring with auxiliary chamber was built. The character of the air spring in vertical direction was described as a linear spring damper element. Using the method of free vibration with damping, the changing rules of the stiffness and damping under different pressure in the air spring with the change of throttle orifice diameter have been studied experimentally.

The analysis results indicate that the vibration fractional factor with rotating frequency has a close relationship with both rotating speed of rotor and damping of bearing under constant acceleration. When rotating acceleration is small and damping is large, the transient response is not sensitive to the variation of rotating speed; otherwise the imbalance response with constant acceleration and the response in stable state will build up obvious differences near critical rotating speed.

研究结果表明：在恒加速条件下，转子同频振动分量与转子的转速、支承阻尼等因素密切相关，当角加速度较小且阻尼较大时，其瞬态响应对转速的波动不敏感；而当角加速度较大或阻尼较小时，恒加速过程不平衡响应与稳态响应在临界转速附近将产生明显的差异。
