Abstract:Rotary head gearbox is Heavy duty hydraulic driven top head rotation head unit with single speed or dual speed arrangement having infinitely variable speed (0 to 500 rpm) and is designed for required user torque and speed. This unit travels on the mast and is of sturdy construction to absorb sudden & varying shock loads generally encountered during drilling operations. Based on requirement selecting the type of Drive whether it is a direct drive or Gear transmission. If we select Direct Drive then the torque and speed to be achieved by the rotary head will depend   upon the torque and speed hydraulic motor.  Only one motor can be used when user selects the Direct Drive. In Direct Drive the Main spindle of Rotary Head is directly connected to the motor shaft by providing the key slot on Main Spindle. Based on application we will be selecting the speeds of gearbox 1 speed or 2 speeds or 4 Speed Gear box. Only for Core Drilling we use 2 speeds or 4 speed gear box. In all other drilling applications single speed gear box has to be used. Doing analysis for maximum loads. In the present work the geometric model is created in Catia Software and imported to hyper mesh for convergent Finite element mesh and analysis. Stress and displacement on travelling block are calculated by using Ansys software.

Abstract:This paper inspect the influence of Normal water & Seawater on curing in concrete cubes which is concealed on clay soil near costal zones with three different percentage of clay at 90%, 50% & 30%. Cement concrete cubes of 150x150x150mm were cast using normal water and cured with seawater & normal water with two different mix proportions M-20 & M-30 with 0.45 water cement ratio. The prepared concrete cubes are concealed in Clay soil to understand the effects of seawater and normal water in terms of compressive strength and NDT test. Compressive strength and NDT test are tested during 28^th day and 84^th day. Totally 108 specimen were cast with normal water. Cement in addition with fly ash class-C of 20% and 30% was also used for this investigation.
Keywords:Clay soil, fly ash, Seawater, Compressive Strength, NDT.

Abstract:In this work, the comparative study of the effect of seawater and normal water on concrete was investigated. This paper represents the speculation research on compressive strength and non-destructive test of concrete in addition with fly-ash class C 20% and 30%. Concrete cubes were cast using normal water for a mix of M-20 & M-30 with 0.45 water cement ratio. This concrete cubes were cured using normal water and seawater. A total specimen of 72 cubes for reference concrete was cast forM-20 & M-30 mix and exposed to a period of 28^thday and 84^th day. The reference concrete was prepared with OPC-43 grade in addition with fly-ash class C 20% and 30% using normal water and seawater for curing. Further, the displayed measured results; show that the diffusivity for sea water contents decreases with increasing 20 % fly-ash class C in M30 grade of concrete.

Abstract:Single point cutting tool is standard tool used for various machining operations. Work is done to find temperature at tool chip interface at various speeds and depth of cut with thermal analysis. The different analyses are done on High Speed Steel tool machining process at three different cutting speeds with varying depth of cut as part of this study. Heat generation analysis is done by varying the geometrical parameters of tool. Investigators made attempt to measure these cutting temperatures with various techniques during machining.  Single point cutting tool has been solid modelled by using SOLIDWORKS 2013 and Finite Element Analysis carried out by using ANSYS Workbench 15. By Varying the depth of cut during the machining the temperature analysis is made with FEA which can be further useful to compare with experimental result.

Abstract:Single point cutting tool is standard tool used for various machining operations. Work is done to find temperature at tool chip interface at various speeds with thermal analysis. The different analyses are done to compare with experimental analysis at low speed, medium and high speeds. These three different analyses are done on High Speed Steel and of a Carbide Tip Tool machining process at three different cutting speeds, in order to compare to experimental results produced as part of this study. Heat generation analysis is done by varying the geometrical parameters of tool. Investigators made attempt to measure these cutting temperatures with various techniques during machining. Single point cutting tool has been solid modelled by using SOLIDWORKS 2013 and Finite Element Analysis carried out by using ANSYS Workbench 15. By varying various parameters the effect of those on temperature are compared with the experimental results and FEA results.

Abstract:A rocker arm is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it. One end is raised and lowered by a rotating lobe of the camshaft while the other end acts on the valve stem. When the camshaft lobe raises the outside of the arm, the inside presses down on the valve stem, opening the valve. When the outside of the arm is permitted to return due to the camshafts rotation, the inside rises, allowing the valve spring to close the valve. This project mainly dealt with modelling of rocker arm and the analysis over that. The modelling of the component was done by using the advanced modelling software CATIA V5. The analysis was done by using one of the most important numerical methods is FEA and the software used is ANSYS 14.0. Importing operation requires a special file format called IGES (initial graphic exchange specification). The geometry model analysis is done and evaluated the all mode shapes with natural frequencies and results are tabulated for the different materials at different load conditions. In this project rocker arm is modelled with the help of CATIA V5 software, and also saved in the form of .stl (stereo lithography).
