Design and Study of Heavy Tipper Multistage Hydraulic Cylinder Based on CAD/CAE
The hydraulic cylinder is an actuator of hydraulic lifting system in the heavy tipper, which also plays an important role in unloading. Aiming at the existing multistage hydraulic cylinder design method's insufficiency, the CAD/CAE technology is introduced into the domains of multistage hydraulic cylinder design. In this paper push-forwarding five-stage hydraulic cylinder is designed, and virtual assembly is established based on three-dimensional digital model using PRO/E sofeware. The multistage hydraulic cylinder's load-supporting characteristics are analyzed by ANSYS. The result of finite element analysis shows that the stress on the top front part of three down hydraulic cylinder is biggest, those on the trunnion and the cylinder's bottom are also bigger. It is also proved that the multistage hydraulic cylinder designed with CAD/CAE technology can satisfy the requirements of intensity, rigidity and supporting stability.
