Design of a mobile hydraulic crane in CAD environment and study of it's control devices

ABSTRACTDesign and simulation of mechanical systems in CAD environment is not only a cost and timeeffective way but also helps us to foreseen the design problems. After modelling a mobilehydraulic crane by using Pro/Engineer software, I?ve selected the hydraulic control devices forthe model. The 3D parametric model is used for dynamic, static and finite element analysis andalso a reference part for conventional calculations.Validation of the software resuts with theconventional calculations, shows us the reliabiliy of the CAD model. However, with some ofthe finite element analysis? it?s very hard to simulate the real conditions and there is always arisk of uncorrect results. To prevent this, sometimes for certain calculations, conventionalmethods are used. By the help of the analysis, the weak designed parts of the construction isrectified quickly, and parametric design of the model contributed to this modifications.In the second case, after finishing the CAD model, I?ve designed the hydraulic system that willmove the crane. At this point, I?ve checked the clearences and packaging of the actuators andmade neccessary modifications easily by the help of parametric modelling.Keywords: Mobile hydraulic, crane, parametric, CAD
