本文介绍南充6102Q型柴油机分别装用竹溪农机厂和无锡减振器厂制造的压入式橡胶减振器时进行的扭振特性试验。试验结果表明:装用竹溪农机厂制造的减振器时,共振转速发生在2800rpm附近,曲轴自由端的合成振幅最大值为±0.28。左右,此值超过了最大许可值(±0.25°);装用无锡减振器厂制造的YXN300B型减振器时,共振转速出现在1839rpm及2443rpm附近,曲轴自由瑞的合成振幅最大值为±0.115°,它低于最大许可值。因此,无锡厂生产的减振器与6102Q柴油机的匹配性能优于竹溪厂生产的减振器。
This paper introduces the torsional vibration characteristics test of Nanchong 6102Q diesel engine with push-in rubber damper manufactured by Zhuxi Agricultural Machinery Factory and Wuxi Shock Absorber Factory respectively. The experimental results show that when the shock absorbers manufactured by Zhuxi Agricultural Machinery Factory are installed, the resonance speed is around 2800rpm, and the maximum amplitude of free vibration of the crankshaft is ± 0.28. , The value exceeds the maximum allowable value (± 0.25 °). When the YXN300B shock absorber manufactured by Wuxi Shock Absorber Factory is installed, the resonance speed appears at around 1839rpm and 2443rpm. The maximum composite amplitude of the free crankshaft is ± 0.115 °, it is below the maximum allowable value. Therefore, the matching performance of the shock absorber manufactured by Wuxi Factory and the 6102Q diesel engine is better than that of the shock absorber manufactured by Zhuxi Plant.
