摘　　要：叉车车架动态特性是影响叉车振动舒适性的关键因素。建立叉车等效振动模型,通过对模型进行谐响应分析,以及综合考虑各种激励方式的影响和各种约束方式的影响,对比几组车架结构改进方案与原车架结构的动态特性,并由此选取最优化的车架结构。Dynamic behavior of a forklift frame is a critical factor effecting the operator's comfort against vibration.Therefore,we had to construct an equivalent vibration model thru which to analyze the harmonic response there,while comprehensively considering types of energizing and their effects as well as types of limitation and their effects.Comparison was also done of improvements to the frame with the original frame in terms of dynamic behavior,before choosing an optimized frame.

关 键 词：叉车车架 谐响应分析 动态特性 激励方式 约束方式
