摘要

针对某V6大功率柴油发动机实际工作中连杆大头侧壁及曲拐侧壁磨损故障的分析,为准确全面的得到分析结果,在某大型V6柴油机曲柄连杆机构动力学分析过程中,对受交变载荷作用下的曲轴飞轮等主要零部件进行柔性化处理,对其曲柄连杆机构进行了刚柔耦合仿真分析计算,研究曲轴动应力状态,为发动机曲柄连杆机构动态应力研究及后续部件间刚度匹配及振动噪声研究提供依据。
        In order to analyze the wear failures of the side wall of the connecting rod and the crankshaft side wall in the actual operation of a V6 high-power diesel engine, the dynamic analysis of the crank linkage mechanism of a large-scale V6 diesel engine was conducted to obtain accurate and comprehensive analysis results. The main parts such as the crankshaft flywheel under the alternating load are flexibly processed, and the rigid-flexible coupling simulation analysis of the crank connecting rod mechanism is performed to study the dynamic stress and strain state of the crankshaft and study the dynamic stress of the crank connecting rod mechanism of the engine, which provides the basis for the stiffness matching and vibration noise study between the subsequent components.
