Design considerations of Gudgeon pin in reciprocating air compressors by semi analytic approach

  The deformation and stress experienced by the Gudgeon pin of a reciprocating compressor used in air brake system is scientifically predicted when the pin is fully floating with lubricating oil surrounding it and when starved of oil. Both semi analytical approach in finite element method and simple bending theory of beams are used. Inadequacy of the beam approach is highlighted. The results obtained by both...

Robust least square estimation of the CRS A465 robot arm’s dynamic model parameters

  This paper presents the experimental estimation of the barycentric parameters of the CRS A465 robot arm. Three methods are used to estimate the barycentric parameters of the arm; ordinary least square method, weighted least squares method and iteratively reweighed least squares method. The estimation is carried out on the complete robot model and the simplified model where the effect of the product of inertia...

Evaluation of the turbulence models for the simulation of the flow over a National Advisory Committee for Aeronautics (NACA) 0012 airfoil

  The analysis of the two dimensional subsonic flow over a National Advisory Committee for Aeronautics (NACA) 0012 airfoil at various angles of attack and operating at a Reynolds number of 3×106 is presented. The flow was obtained by solving the steady-state governing equations of continuity and momentum conservation combined with one of three turbulence models [Spalart-Allmaras,...

Adaptive neuro-fuzzy inference system (ANFIS) based surface roughness prediction model for ball end milling operation

  Surface roughness is an index which determines the quality of machined products and is influenced by the cutting parameters. In this study, the average surface roughness Ra(value) for aluminum after ball end milling operation has been measured. 84 experiments have been conducted using varying cutter axis inclination angle (φ degree), spindle speed (S rpm), feed rate (fy mm/min), feed...
