The design of hydraulic cylinder including ensure pressure system of the hydraulic cylinder piston, piston rod diameter and the diameter and wall thickness and diameter of hydraulic cylinder cylinder, the thickness of the calculation of the length, and the cylinder piston rod stability of calculation. In this thesis, by the use of traditional design and computer-aided engineering（CAE）, firstly based on experience of the formula calculation to determined the installation scheme of the hydraulic cylinder, design size parameters of hydraulic cylinder piston and piston, Check the matching of connecting bolts, pin shaft, etc.;complete the design and calculation of the range and angle of hydraulic cylinder. Then by the use of AutoCAD,Pro / MECHANICA platform, Complete all parts of the hydraulic cylinder 2d and 3d modeling.The analysis data verificated the previous design, at the same time ,applied references for further Optimal Design and Series Design. Keywords: The luffing hydraulic cylinder，Variable Angle of
