Abstract: Composite materials are widely used in the various Fields. Due to the high strength they are widely used in the low weight constructions and also used as a suitable alternative to metals. In various applications and also for joining various composite parts together, they are fastened together using adhesives or Mechanical fasteners. Modeling and static analysis of 3-D Models of joints such as bonded, riveted and hybrid. The results were found in terms of vonmises stress, shear stress, and normal stress for stress distribution. ANSYS FEA tool has been used for stress distribution characteristics of various configurations of double riveted single lap joint with three joining methods namely bonded, riveted and hybrid the present study deals with the analysis of single lap joint subjected to the given tensile load and the stress distribution in the members under various design conditions are found.

Keywords: composite materials, FEA–Ansys, joint strength, bonded, riveted, hybrid.

Abstract: Water is the life-blood of the environment, without water no living beings can survive. Water plays unique role in development of all sectors in any economy of every country. Water is used for agricultural, domestic, industrial, power generation and other various purposes. But misuses of water resources cause widespread degradation of soil and disrupt the supply of potable water, generate massive economical loss. Hence it becomes necessary to harness the water resources available on Earth through the application of science and technology. This paper presents one such case study where large amount of rainwater is possible to direct to recharge ground water resources. Kaneri is a small village located at distance of 10 Kms. from Kolhapur city. It is planned to take such engineering and biological measures which will direct this extra runoff to ground water storage. The most significant feature of the work is that if such technologies are developed and adopted at larger scale in rural areas, it will prevent thousands of villages of the country from water supply by tankers. Moreover this will also help us for economical development of village people which mainly occurs due to water scarcity.

Abstract: To convert the existing grinding machine into a good working machine, a ball screw mechanism is designed and incorporated in the existing grinding machine by retrofitting process. Grinding machine removes material from the work piece by abrasion, which can generate substantial amount of heat. Therefore a coolant System is incorporated to cool the work piece, so that it does not overheat and go out of its tolerance. Grinding practice is a large and diverse area of manufacturing and tool making. It can also rough out large volume of metal quite rapidly. It is usually better suited to the machining of hard materials. Cylindrical grinding is also called center type grinding. It is used in the removing the cylindrical surface and shoulders of the work piece. The five type of cylindrical grinding are outside diameter (OD) grinding. Inside diameter (ID) grinding, plunge grinding, creep feed grinding and center less grinding.It is used in the industries for grinding the nozzle body. The grinding machine can be changed to automatic machine according to one of the latest technologies called PLC's controller. The manually operated grinding machine has some of the in-accuracies and disadvantages compared to new modern CNC grinding machines.Based on the case study of both manual and CNC grinding machine, the manual machine is converted into automatic machine for the better accuracy and efficiency. The main replacement of the machine parts are hydraulic cylinder and stepper motor by ball screw mechanisms and servo motor.

Key words: - Retrofitting, Cylindrical Grinding, Servo Drives, Ball Screw
