College CET CODE 112

Mechanical Laboratory

R & D Center

Department of Mechanical Engineering is VTU recognized Research and Development Center.

The department is funded from VGST under which different equipments like Computerized UTM, Fatigue Test Rig, Digital microscope and Digital Vickers Hardness Testing Machine are procured. More than 10 faculties of the department are pursuing PhD.

ENGG.GRAPHICS AND DRAWING LAB

This lab helps the students to acquire knowledge of CAD software and its features. Students learn the theory of projection, make drawings using orthographic projections and sectional views and to familiarize the students with ISO standards. Also make them understand and interpret drawings of machine components so as to prepare assembly drawings both manually and using CAD packages like solid edge and AutoCAD

MATERIAL TESTING LAB

This lab helps the students to acquire knowledge about material by conducting test like destructive and nondestructive testing. On ferrous and nonferrous materials. In destructive testing tension, compression, shear, impact, hardness, bending, fatigue, creep, torsion and wear test are performed. In nondestructive testing magnetic particle and chemical spray testing is done. Also microstructure analysis for different materials is observed. Students and faculty also involve in preparing the specimens for testing and research is carryout in this lab. VGST has sponsored for the upgradation of the lab digital UTM, Digital fatigue, Digital Vickers hardness, digital metallurgical microscope and polishing machine are procured under this grants.

MECHANICAL MEASUREMENT AND METROLOGY LAB

In this lab students are able to understand different measuring instruments to measure the qualitative and quantitative characteristics of different Mechanical Measuring equipments. To express the significance of measurement systems such as errors, transducers, intermediate modifying errors and correction factors of various measuring devices, by using different measuring tools such as Sine Bar, Sine Center, Bevel Protractor, Tool Maker Microscope, Gear Tooth Micrometer, Optical Flats, Linear variable differential transformer, dynamometer and profile projector experiments are conducted. All the above instruments are calibrated with the standards.

MACHINE SHOP LAB

The students will be trained to operate and use different machines like Lathe, Milling machine, Grinding machine and Shaping machine. In each and every machine students are made to manufacture three different models individually. The students will be exposed to operate the machines for manufacturing any complicated component.

ENERGY CONVERSION LAB

Students are taught to conduct experiments on two stroke, four stroke, petrol and diesel engines.

For all the engines the performance characteristics is evaluated by both theoretically and experimentally. For all the experiments the students are made to determine the engine efficiency at different loading conditions.

Before performing the experimentation the fuel is prepared and its characteristics are determined like flash point, fire point, viscosity, specific gravity using calorimeters.

The lab is equipped with latest computerized test rig.

FLUID MECHANICS & MACHINERY LAB

This lab is run in conjunction with the theory course Fluid Mechanics. It is an introductory course where flow behavior and fluid forces are studied. The goals of the experiments include determination of forces generated when fluid flow takes place over a solid object.

Applications of the control volume approach, demonstration of the momentum and energy equations, viscosity measurement and engineering correlations are studied. Intricate flow phenomena such as separations and transition to turbulence are demonstrated. Experimental setups such as flow through a tube, flow over a flat plate and viscometer are made available to the students.

This lab trains the students to perform the coefficient of discharge using flow measuring devices like Orifice and Venturimeters. Test basic performance parameters of hydraulic turbines and pumps. Determine the energy flow pattern through the hydraulic turbines and pumps.

DESIGN LAB

The lab provides the advanced knowledge in understanding the concepts of Mechanical Vibrations & Dynamics of Machine. The students perform experiments on advanced Gyroscope, Journal bearing, Polariscope, balancing of rotating masses, Whirling of shafts, Vibration test rig and strain rosettes. The students will learn to control vibrations in different working conditions.

HEAT TRANSFER LAB

Heat Transfer laboratory provides fundamental and industrial knowledge about modes of heat transfer like conduction, convection and radiation and their applications. Also students will perform experimentation on refrigeration and air conditioning cycles to determine the thermal conductivity of metal rod, convection and correlate with theoretical convective heat transfer coefficient for free and forced values. Also they will calculate temperature distribution of steady and transient heat conduction effectiveness of fin wall.

MODELING AND ANALYSIS LAB

Modeling and analysis lab is associated with FEM theory subject. The fully Licensed version of ANSYS software is used in the laboratory which helps for research and consultancy projects . The student learns to use the software for preprocessing, processing and post processing operation on 2D, 3D, static, dynamic, heat transfer and flow problems. The results are evaluated by both mathematical and computational methods for bar, beam, structural, plate and for combination of materials.
