Theoretical Design and Analysis of Ring Spanner by using ANSYS

Abstract

: Ring spanner is an important tool in the machine industry and its demand is increasing day by day, which forces us to analyse and improve design to improve work performance and tool efficiency. The focus of this study is to determine the stress and deformations occurring in a loaded ring spanner. To analyse the spanner in detail a model is made where the geometry is simplified to a plane model. this research paper considered chrome vanadium material for ring spanner. The spanner is designed in “Catia v5” with a gauge length of 150 mm; the big end of the spanner is an internal diameter of 32 mm and a small end internal diameter of 28 mm as shown in table 1. The design file in Catia saves in an extension of .stp. The model finally imported into Ansys software for analysis. The material selected is Chrome Vanadium with properties inserted into the ‘Engineering Data Source’ all parameters given in Table 2 below. For analysis purpose, the big end ‘A’ is being supported as fixed and on the left side, a remote force of 500 N in an anticlockwise direction is applied in a static structural Mechanical analyzer. The mesh of the model is fine, the number of nodes and element are 49333 and 30326, an element size of 2.5e-003 m. The overall volume and mass are 4.9667e-005 m³ and 0.38988 kg.
