THREE DIMENSIONAL STRESS ANALYSIS OF RADIAL GATE USING FEM (ANSYS Software)

Abstract

The hydraulic gates are moving facilities provided in dams, barrages, hydropower projects, reservoir and, canal for flow control. Hydraulic gates are most important component of any water resources projects. Thus it needs specialized and expertise in regard to selection, planning and design, erection and maintenance. Any deviation in fulfilling the intended purposes can have devastating results, and sometimes may endanger the safety of the entire project. Mostly vertical lift gates and radial gates are used in water resources projects. These gates are designed as per guidelines followed in different Indian Standard Codes. These are based on mostly 2 D design approach. However in actual practice, structure behaves as 3 D structure.' Hence displacements and stresses are developed in all three directions. The exact nature of stresses and displacement in different parts of gate, like joint between horizontal girder and vertical stiffener, horizontal girder & radial arm, radial arm & trunnion is quite complex and can be analyzed through 3 D analysis only....
