Research on Field Dynamic Balancing Test Technology for Certain Type of Non-Road Diesel Engine
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.
