DESIGN AND STATIC ANALYSIS OF THREE AXIS PNEUMATIC DUMPER

Dumpers have always played an important role for carrying bulk loads, often for carrying building loads. To dump the materials at particular site in the proper direction is challenging at a construction site. It is usually time taking and difficult to keep dumper in assigned position in order to dump the materials. To overcome this limitation the modification in the design of existing dumper is necessary for easier dumping of materials. In this work, a new design is proposed for dumper which is movable in any direction to dump the material; the three-dimensional motion is achieved by introducing a pneumatic cylinder along with a chain sprocket mechanism. In this research work a three axis pneumatic dumper has been designed and analyzed using Finite Element based software ANSYS^® to overcome the difficulty in unloading the materials in small compact streets and small roads. Static structural analysis is carried to evaluate maximum equivalent stress, shear stress, elastic strain, total deformation of three axis pneumatic dumper. It is observed that the results obtained by computer analysis of three axis dumper are well corroborated with the results obtained in physical aspect on foreground. By using a modified design, the dumper is capable of tilting in three directions without application of any impact force.
