Reliability Analysis of Piston Manufacturing Plant

Abstract

The Thesis entitled “RELIABILITY ANALYSIS OF PISTON MANUFACTURING PLANT” is an attempt to develop a mathematical model for analyzing the reliability of piston manufacturing plant. The piston is widely used in almost all the vehicles. This study has industrial significance to determine the quality characteristics for customers and is used for products, systems, processes and components of system.’ The Thesis has been divided into three chapters. The brief outline of the research work presented chapter wise in this thesis is as follows: First chapter is introductory in nature. In this chapter, definition of reliability and basic concepts are discussed. A brief summary of literature available on the subject and summary of the work presented in the thesis also appears in this chapter. In the second chapter, the reliability of piston manufacturing plant has been analyzed. The plant consists of fifteen sub-systems, namely Fixture Seat Machining, Rough Grooving and Turning, Rough Pin Hole Boring, Oil Hole Drilling, Finishing Grooving, Finish Profile Turning, Finish Pin Hole Boring, Finish Crown and Cavity, Valve Milling, Chamfering or Radiusing, Circlip grooving, Deburring, Cleaning, Surface Treatment, Final Inspection. Rough Pin Hole Boring, Finish Pin Hole Boring and Finishing Grooving can also work in reduced state. The mathematical formulation of the problem is carried out using Markov-method. The Chapman-Kolomorgov differential equations thus developed and are solved by numerically to find out the reliability. The effect of constant failure and repair rates on the reliability has been studied in detail with the help of tables. In third chapter, we have presented industrial significance of the present work. The limitations and future scope of the research work are also discussed in this chapter.
