摘要
聚焦某型非道路柴油机在额定转速范围内因挠性现场动不平衡导致的基频振动过大问题。研究通过锤击法精确测定曲轴固有频率,并结合现场动平衡测试技术,对曲轴轴系进行优化调整,以达到预期的振动控制指标。不仅成功解决了该机型的基频振动难题,更重要的是为测试人员提供了现场动平衡测试技术的理论基础和实践指导,形成了一套行之有效的测试方法和流程。本文的研究成果为柴油机轴系平衡出现类似问题提供了宝贵的方案参考。
This article focuses on the problem of excessive fundamental frequency vibration caused by flexible field dynamic imbalance in a certain type of non-road diesel engine within the rated speed range.The research accurately determined the natural frequency of the crankshaft by hammering method,and combined with field dynamic balance testing technology,optimized and adjusted the crankshaft shaft system to achieve the expected vibration control indicators.This work not only successfully solved the fundamental frequency vibration problem of this model,but more importantly provided testers with a theoretical basis and practical guidance for field dynamic balance testing technology,forming a set of effective testing methods and processes.The research results of this article provide valuable reference solutions for similar problems in diesel engine shaft balance.
