智能柴油机的扭振优化控制方法研究

The Study of the Optimization Control Method of Torsional Vibration of Intelligent Diesel Engine

针对传统扭振控制方法已不能满足现代柴油机技术发展的需求,提出基于智能柴油机工作参数可调的扭振优化控制新方法。以某高压共轨中速机为对象,研究柴油机工作参数,如喷油定时和进气定时的改变与扭振应力间的关系,并进行了扭振优化计算与验证,取得了较好的扭振优化控制效果。

The traditional torsional vibration control methods can＇ t meet the needs of modem diesel tech- nology, therefore, the optimization control method of torsional vibration based on controllable parameters of the intelligent diesel engine was put forward. A high-pressure common rail medium-speed engine was chosen to study the relationship between the variation of diesel engine＇ s operational parameters, such as injection timing and air intake timing, and torsional vibration stress. Moreover, torsional vibration optimi- zation calculation and tests were carried out, and finally obtained good results in torsional vibration opti- mum control.
