深入分析了柴油机曲轴轴系扭转振动的基本理论及其特性,给出了合适的柴油机轴系当量物理模型及其数学模型,并确定了分别采用霍尔茨法、能量法对自由振动和强迫振动进行计算,在此基础上开发了基于VC++面向对象的柴油机轴系扭振计算分析软件。给出了理论计算与实测数据的比较,结果表明,利用所开发的软件能够进行柴油机轴系扭振的综合计算与扭振同特性分析,软件具有工程应用价值。
In this paper, profound analyses on the torsional vibration theory and characteristics of diesel engine crankshafts were carried out, the reasonable equivalent physical model and mathematical model for the engine crankshaft vibration were given. Furthermore, Holzer theory and the principle of conservation of energy were determined to process the problems of the natural vibration and forced vibration, respectively. Based on above, software was developed to compute and analyze the characteristics of torsional vibration of crankshaft in diesel engine. In comparisons of computed results with the experiments, it showed that the developed software is practicable in conducting comprehensive computations and characteristics analyses for the diesel engine crankshaft torsional vibration.
