作者通过大量理论分析、模拟计算和实验研究，首次全面系统地解决了根据内燃机曲轴某一测点的角振动曲线诊断内燃机各缸作功状况的诊断方法和相关诊断测试设备研制等问题。 - In the training process , developing the students ' divergent thinking ability enables students to be active and search for the various solutions of the problems , and by virtue of the specific experiments to test and explain the physical theorem and phenomenon
在具体实施过程中，注重培养学生发散思维的“两多” ，利用“一量多测” 、 “一测多变”和“一仪多用” ，来寻求习题多种解法，并通过具体实验来验证物理定理，解释物理现象，从而让学生在学习中始终处于积极、主动状态；大大提高了学习物理的兴趣。 - 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。
