This document summarizes a study on analyzing the behavior of a steam turbine rotor under low volume flow conditions using rotor dynamics concepts. A Jeffcott rotor model was created and analyzed using finite element analysis in ANSYS. Both a standard single stage Jeffcott rotor and a modified single stage rotor were analyzed and their equivalent stresses, maximum principal stresses, and total deformation were compared. The analyses found that stresses were within allowable limits during normal operation but exceeded limits under low volume flow conditions. A modified multistage rotor model was also analyzed and compared to a standard multistage rotor model. The results of the modal, static, and harmonic analyses were presented.
Fea analysis and optimization of an one way clutch used in automatic transmis...eSAT Journals
Abstract An intent of this project is to reduce the weight of one way clutch which is being used in automotive transmission enabled sports cars. By reducing the weight we can achieve better efficiency in terms of strength and also to increase the transmission power from torque converter wherein which engaging and disengaging happens. One way roller clutch is one, when the unit rotates in one direction the rollers slip or free-wheel, but when a torque is applied in the opposite direction, the rollers lock between outer cage (cam) and inner cage, producing a wedging action and binding because of friction. The rollers are spring-loaded. Design parameters like maximum torsional deflection, minimum hoop`s stress are considered for to get increased efficiency. In order to achieve this FEA analysis and optimization technique is carried here. Optimization is the mathematical discipline which is concerned with finding the maxima and minima of functions, possibly subject to constraints. Here optimization is carried out by using the global parameters optimization technique. Keywords: FEA analysis, Global parameters, Minimum hoop`s stress, Weight

Analysis of Rack and Pinion under dynamic conditionsnagaraju kondrasi
Based on physical and thermal properties graphite cast iron has got more strength than sand cast Mg alloy and it is clear from the results that the load carrying capacity of former is larger than the later. Hence Graphite cast iron is preferred for the manufacture of rack and pinion.
In static structural analysis the total deformation and von - mises stresses are more in sand cast Mg alloy than graphite cast iron. Hence graphite cast iron has better strength than Sand cast Mg alloy.
In modal analysis the number mode shapes are higher for graphite cast iron than sand cast Mg alloy.
Under transient conditions the total deformation of Graphite CI is less than that of Sand cast mg alloy. Hence former is preferred under Transient conditions.
Under fatigue loads the damage is more in sand cast Mg alloy. Hence graphite CI is preferred for manufacturing of Rack and pinion.
Hence Keeping all the analysis in view the graphite cast iron is preferred over sand cast Mg alloy.

Design & analysis of needle roller bearing at gudgeon pin of ginning machineeSAT Journals
Abstract
Needle roller bearings have high load carrying capacity although it have small cylindrical roller having low cross section,
thus it used in application where space limitation is the important factor along with high dynamic loading capacity. So in
ginning machine where space is limited for driving the mechanism a Needle roller bearing having diameter of 20 mm is
used in between connecting rod and head pin to give the relative motion between parts. As the continuous impacting of
repetitive load on bearing, it fails with in shorter period of time if proper lubricant is not supplied by grease gun after 2 to 3
hours. While bearing are considered under observation it is found that bearing are fail due to brinnelling. So design and
analysis of needle roller bearing is vital to calculate the life of bearing and to make sure whether this bearing is suitable or
not. So it becomes mandatory in designing to calculate radial load applied on bearing as the bearing is rolling contact
bearing, from this life of the bearing can be calculated and finally analysis by ANSYS software is done to find the result so
that we can conclude for bearing.
Key Words: brinneling, connecting rod, dynamic load capacity, head pin, life, radial load, repetitive load

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
