| 摘 要： | 通用汽油发动机曲轴动平衡测试及自动去重校正系统,由于以压电陶瓷振动传感器作拾振器,其输出是微弱信号,须经滤波放大预处理.再采用影响系数法处理动平衡测试数据并拟合插值,实现各信号周期和采样点的严格同步.同时用谐波分析法,以提高动平衡幅值测试的精度.系统的去重则通过在曲轴的2个扇形面上钻孔实现.

| Abstract: | The crank-shaft dynamic balancing testing and automatic machining system about general gasoline engine, because it adopted the vibration sensor of piezoelectric ceramic, so its outputs was faint signal and was pretreated by filtering amplifier. Then, the influence coefficient method was used to deal with the dynamic balancing testing data and fit the inserting value for realizing every signal cycle and sample point move ahead simultaneous strictly. The analytic method of harmony wave was adopted at the same time, in order to improve the precision that dynamic balancing amplitude tests. The system machining was realized by drill hole on the two pieces of fan-shaped of crank-shaft. |
