Vehicle dynamics is the study of  behavior of vehicles in motion . The study is one of the most important activities in the Vehicle design and development cycle to design vehicles which drive well and are comfortable to ride in.

In this course, you will learn the

• Concepts and mechanisms which govern the actions and reactions in vehicles all the way from how vehicles accelerate, brake, turn and respond to vibrations.

• The Theory and concepts behind suspension design process including concepts of kinematics and vibration isolation.

This course will first build on the very basics of automotive engineering and Newtons laws of physics , friction etc and then move on to explain the phenomena taking place between the Vehicle and the road in different circumstances. At each section of the course you will be taking away insightful concepts with the understanding of How? and Why?

The course is filled with 5+ hours of conceptual learning which lays a strong foundation to understand the more advanced concepts of vehicle dynamics and suspension design.

This is not a mathematically intensive course and it doesn't aim to delve deep into the numerical treatment of dynamics rather aims to explain the underlying principles and concepts which are at play to govern the behavior of the vehicles.

You might have come across terms like roll, under-steer, camber ,caster and many more but don't really know what they mean and how important they are for the vehicle. This course will clear out those concepts.

If you are a beginner to the field and want to learn the concepts in an easy way , this course is for you.

If you are already into the field of vehicle dynamics , this course will serve as a reference to clear out concepts on basic aspects of vehicle dynamics.

The course contains hardly any math or high level physics concepts. If you are having a basic background in Math and physics , this course will help you understand Vehicle Mechanics at Entry level.
