多功能电子式扭振标定器的研制

Development of Multifunction Electronical Calibrater of Torsional Vibration

为了能够对内燃机扭振测量系统进行标定,本文研制了一种电子扭振标定器。这种标定器与国内外同类产品相比,除了转速可变外,还有一些创新之处:齿数可调、输出幅值可调、同时可以输出每周一个的上止点参考信号。实验结果表明本标定器性能良好。

In order to calibrate the measuring instrument for the torsional vibration in internal combustion engine, an electronic torsional vibration calibrater is developed in this paper. Comparing to the other kindred products, besides adjustment of speed, the new calibrater can adjust teeth number and output voltage. The new calibrater can also export the top dead center signal in each cycle.
