Abstract
This paper is mainly to design the Work installment of excavator in the : Moves arm, Doo-under bucket, Pin, connecting rod Institutions based on using the original data of small excavators and the Empirical formula,the Revolving vector method ,also the Mechanics computation. In this paper on the first working device in the structure of the various agencies to identify and select the initial location and layout of the original data set. Second through the whole device can be simplified treatment, to map out the work of the agency after the model of the boom, the various components, such as Doo-bodies kinematics analysis, the analysis determined by calculating the size of the basic institutions. And then, strenuously, accepting passing to each organization under different working condition or peculiar limit working condition analyses and calculates the parameter carrying out physical design and ascertaining each dimensions.At last accomplish this design behind selecting and using ascertaining standard pieces such as axis pin and bolt.
Keywords: Excavator, Structure , Stress analysis, Empirical formula
