Frequency Analysis of a rotating shaft

AIM: To perform the frequency analysis of the rotating shaft using solidworks. INTRODUCTION: Natural frequency: Natural frequency, also known as eigenfrequency, is the frequency at which a system tends to oscillate in the absence of any driving or damping force.The motion pattern of a system oscillating at its natural…

AIM: Design and motion analysis of 'IC ENGINE VALVE TRAIN' using solidworks. THEORY: A  valve Train is a mechanical system that controls operation of the intake and exhaust valves in an internal combustion engine. The intake valves control the flow of air/fuel mixture (or air alone for direct-injected…

AIM: Design and Motion Analysis of Planetary Gear System using Solidworks. THEORY:  A planetary gear set is made up of three types of gears; a sun gear, planet gears, and a ring gear. The sun gear is located at the center and transmits torque to the planet gears which are typically mounted on a moveable carrier.The…

AIM: Design and motion analysis of 'IC ENGINE PISTON ASSEMBLY' using solidworks. THEORY:                                                                  …

AIM: Write a code to fit a linear and cubic polynomial for the Cp data. THEORY: Curve fitting is the process of constructing a curve, or mathematical functions, which possess the closest proximity to the real series of data. By curve fitting, we can mathematically construct the functional relationship between the observed…

QUESTION: Determine the nodal displacement of 1-D bar with uniform cross-section  as shown in the above figure using elemental matrix equation.The length of the bar is 100mm and the area of cross-section is 150mm^2 .The value of Young's Modulus is 200KN/mm^2.The bar is fixed at one end  and the force of…

AIM: Parsing NASA thermodynamic data by using matlab. THEORY: What is File Parsing? -The term ‘parsing’ refers to MATLAB reading an m-file (script or function) and translating it into an internal code that it stores in memory. It is this ‘parsed’ file in memory that is actually…

AIM: To create a basic 'RANKINE CYCLE SIMULATOR'. THEORY: The Rankine cycle is the fundamental operating cycle of all power plants where an operating fluid is continuously evaporated and condensed. The selection of operating fluid depends mainly on the available temperature range. The above figure shows us the basic rankine…
