Design and application of the experience design method and computer aided engineering technology, according to the empirical formula, determine the hydraulic cylinder installation project, design of hydraulic cylinder piston and piston rod size parameters, check matching bolt, pin. Finally with the drawing software CAD complete hydraulic cylinder assembly drawing,Using solidworks motion simulation and analysis Through the three cylinder motion simulation and analysis demonstrate that the design is reasonable and feasible. Reduce design costs, reduce product development time. Enables graduates to become more familiar with product design and development process, proficiency in design software for its future work to lay a solid foundation.
