Vibrations are oscillations which repeats after equal interval of time in mechanical dynamic systems.

Although any system can oscillate when it is forced to do so externally, the term “vibration” in mechanical engineering is often reserved for systems that can oscillate freely without applied forces.

Sometimes these vibrations cause minor or serious performance or safety problems in engineered systems.

For instance, when an aircraft wing vibrates excessively, passengers in the aircraft become uncomfortable especially when the frequencies of vibration correspond to natural frequencies of the human body and organs.

Hence the objective of the course are

1.     To understand the Fundamentals of Vibration and its practical applications.

2.     To understand the working principle and operations of various vibration measuring instruments.

3.     To be creative problem solvers whilst dealing with machinery involving periodic phenomena.

In this course the topics are covered to fulfil the above objectives and also at the end of this course students will be able to

CO1     : Define the basic terms of vibrating system

CO2     : Illustrate and identify the basic components of vibrating system

CO3     : Formulate mathematical models of problems in vibrations using Newton's

               second law or energy principles

CO4     : Determine a complete solution to mechanical vibration problems using

              mathematical or numerical techniques

Vibration is a common phenomenon occurring in a mechanical system. For example, vibration of a rotor due to unbalanced mass, vibration of a vehicle engine at varying speed. The study of a dedicated course is required to understand the fundamental and advance concepts of mechanical vibrations for engineers and designers. It introduces fundamentals of vibration, free and forced, undamped and damped vibration, vibration of single Degree of Freedom (DoF) system, 2-DoF and multi-DoF systems, theory of vibration absorbers and vibration instruments. It also explains the two categories of acoustics  namely 1. Sound. A disturbance in an elastic medium resulting in an audible sensation. Noise is by definition unwanted sound. 2. Vibration. A disturbance in a solid elastic medium which may produce a detectable motion.  In reality sound and vibration are often interrelated. That is, sound is often the result of acoustical energy radiation from vibrating structures and, sound can force structures to vibrate. 

Upon completion of this course, the students will be able to:

TQM  is a management approach to long-term success through customer fulfilment. Each individual member of an organization involved in improving processes, products, services, and the working culture. TQM can be summarized as a administration framework for a customer-focused organization that includes all workers in nonstop advancement or continuous improvement. TQM uses technique, information, and compelling communications to coordinated the quality teach into the culture and exercises of the organization. TQM is significantly improving the organization efforts to achieve their goals in an effective and efficient manner and well suited to all kinds of industrial sectors.  Benefits of TQM involves Cost reduction, Improved Productivity, Improved Customer satisfaction, Reduced defects, Enhanced employee morale

At the end of this course the students will be able to 

CO1: Identify customer needs and convert those as quality index that will be used as inputs in TQM methodologies.

Integrated product and process development combines the product design processes along with the process design process to create a new standard for producing competitive and high-quality products. This course involve the concepts from Process planning and cost estimation, Concept of Engineering design, Industrial Management and Engineering and how they are helpful in design and development of a product.

Integration of new technologies and methods provide a complete new dimension to product design process. This process starts with defining of the requirements of products based on the customer feedback while considering the design layout and other constraints. Once the finer details are finalized, they are fed into CAD models where extensive testing and modeling are done to get the best product.

With integration of production method and technology with product design, it is natural for integration of product design and process design. Therefore, integrated product and process development can be defined as a process starting from product idea to development of final product through modern technology and process management practices while minimizing cost and maximizing efficiency.

upon completion of the course the students will be able to,
