摘要

柴油发电机组由于其多功能性和成本效益,通常用作交通运输中的动力源。在停机过程中,柴油发动机的气缸压缩压力会通过曲柄连杆机构在传动系统中引起强迫振动,导致不稳定负载,从而威胁轴承寿命。为了解决这个问题,提出了一种耦合正向设计方法,该方法考虑了非稳定载荷对轴承寿命的影响。对16V280柴油发电机组停机过程进行了试验研究,建立了传动系动力学模型。引入了连接非稳态载荷和轴承寿命的累积损伤值,以量化非稳态载荷对停机过程中轴承寿命的影响。非稳定载荷包括扭矩波动和碰撞力。结果表明,减小传动系键隙,提高联轴器刚度,可以降低轴承的组合载荷,提高轴承的使用寿命。设计了一个大刚度联轴器,以实现停机平稳性和轴承寿命损伤减少43.19%,证实了该设计方法在轴承寿命方面的可行性。

Influence of the shutdown process of the driveline on the generator bearing life in the diesel generator set
Diesel generator sets are commonly used as power sources in transportation due to their versatility and cost-effectiveness. During the shutdown process, the diesel engine’s cylinder compression pressure would cause forced vibration in the driveline system through the crank linkage mechanism, resulting in unsteady loads that pose a threat to the bearing life. To address this issue, a coupling forward design method is proposed that takes into account the impact of unsteady loads on bearing life. An experiment was conducted on a 16V280 diesel generator set shutdown process, and a driveline dynamic model was established. The cumulative damage value that connects unsteady loads and bearing life was introduced to quantify the effect of unsteady loads on the bearing life during the shutdown process. The unsteady loads included torque fluctuation and collision forces. The results showed that reducing the driveline key gap and increasing the coupling stiffness can decrease the combined load on bearings and improve bearing life. A large stiffness coupling was designed to achieve shutdown smoothness and a 43.19% reduction in bearing life damage, confirming the design method’s feasibility concerning bearing life.
