说明：  提出了柴油机滑动主轴承轴颈运动惯性的计算方法，通过对主轴颈垂直运动惯性的 理论分析和主轴承磨损故障的模拟试验，揭示了柴油机机身侧面冲击振动的内部激励源及其与柴油机工况、润滑油温度和主轴承间隙的内在联系，
(Made main bearing journal diesel engine inertia is calculated by the vertical movement of the spindle neck inertia of theoretical analysis and simulation of failure of main bearing wear tests reveal engine inside the fuselage side of the vibration excitation source and its diesel engine conditions, oil temperature and the main bearing clearance of the internal relations)
