摘　　要：振动是影响通用小型汽油机可靠性、耐久性的重要指标。按照国家标准GB/T10398推荐的试验装置要求建立了一套通用小型汽油机振动测试系统,以168F汽油机为研究样机,分析了通用小型汽油机的结构特点及影响振动的因素;对168F汽油机进行多工况的振动测试与分析,结果表明168F汽油机由于采用无轴平衡方式平衡往复惯性力,整机当量振动烈度偏大,分析给出了减小振动的方法和措施。Vibration is an important factor to the dependability and durability of non-road spark-ignition small engine.Based on the 168F gasoline engine,build a system for the vibration test of non-road spark-ignition small engine and do a vibration test instructed by the standard GB/T 10398＂Small gasoline engines-Evaluation and measurement of vibration＂.Analyse its structure and vibration factors;Do vibration test on several work conditions and analyse the results.Test results show that the equivalent vibration intensity of 168F gasoline engine is big,for there＇s no balance shaft to balance the reciprocating inertia force.Explain the methods to reduce vibration.
