内燃机动力学 meaning in English

ic engine dynamics
ic engine regulation

To adapt the circumstance in which the crankshaft torsional vibration generally exists , the new method ( tvrs method ) in which the cylinder power is inversely solved according to the torsional vibration curve is put forward and deduced in this paper , that is , the average effective pressure of each cylinder i . e . power condition of each cylinder is estimated based on a crankshaft torsional vibration curve according to the elasticity model of the actual shafting of engine and by use of the i . c . engine dynamics , the numerical calculations and the signal theory etc . although the computing workload is more , the method makes full use of the now available data of the torsional vibration of the i . c . engine , and can be used to all kinds of i . c . engine on any kind of operating condition , so it has higher application value
为适应内燃机普遍存在曲轴扭振的情况，本文提出并推导了利用扭振信号反算的新方法( tvrs法) ，即采用轴系中某一测点的扭转振动信号，按轴系实际的弹性模型，依据内燃机动力学、数值计算方法和信号理论等，反算各缸的平均有效压力，定量判断各缸的作功状况。此法充分利用内燃机现有的扭振资料，虽然计算工作量较大，但普遍适用于各种类型各种工况的内燃机，有较高的实用价值。
