【摘要】YT1000 型振动压路机是一种小型电能振动压路机,其振动轴设计成一个吊篮的形状,
简化的振动系统使压路机的制造成本和维修费用大大降低。振动轴是连接车架与钢轮的重要部件,是
振动轮的主要部件之一。压路机在工作时,振动轴用在车架与钢轮之间传递铅垂力、纵向力和横向力,
同时又承受偏心块所产生的离心力。通过 PROE 软件对振动轴进行了三维建模,并导入 ANSYS 软件再
进行模态分析,得到了振动轴的前 8 阶固有频率和振型。分析所得结果为振动轴结构的优化和设计的
合理性提供了理论依据,为新型电能振动压路机的振动轴动力学分析打下基础。对压路机的振动系统
设计做了一定的探讨。

【Abstract】The vibrating shaft of YT1000 electrical vibratory roller is designed with the shape of na-
celle, and the simplified vibrating system will decrease much of the cost of the vibrating shaft is
,
not only an important part in connecting the frame and the steel wheel but also one of the main parts of the
vibratory the roller is working, the vibrating shaft is used to transfer the leading vertical force、
the longitudinal force and the horizontal force between the frame and the steel wheel, and to support the
centrifugal force which
