Description

Testimonials from students of Designing Mechanisms using Fusion 360:

"Video content is high quality and very professional. Subject matter is relevant and is backed up with real world examples. Narrator is easy to understand with a good grasp of the English language. The content is perfect for designers wishing to expand their toolbox of mechanical design knowledge. This allows designers to engineer complex mechanism that would normally be the realm of professional engineers. The design practices can be used with any CAD system and is not just a AutoCAD (Fusion) 360.
Keep up the good work."

==========================================================================================

In this course you will learn the basics of Mechanism Design. This course is based on two textbooks:

  1. Kinematics and Dynamics of Machinery by Robert L.Norton.
  2. Machines and Mechanisms: Applied Kinematic Analysis by David H. Myszka

This course is equivalent to what is taught in Mechanical Engineering course in universities around the world. By building on the same excellent textbooks in this course I will teach you not only the theory but also the applications in Fusion 360. At first, you will learn about the exciting field of Mechanism Design and its applications that surround us. This is followed by an overview of the different branches of Mechanism Design: Kinematics and Kinetics. Afterwards, you will earn about the theory of Kinematics before you apply your knowledge to design projects in section three. 

This course covers Kinematics with focus on Graphical Mechanism Design methods using Fusion 360. In section two you will learn about the basic concepts of Kinematics: Types of motion, Links, Mobility, Joints and so on. This section will focus on four-bar linkage's types and categories. Four-bar linkages are widely used in everyday life; from window pivots to windscreen wipers. Four-bar linkages are very flexible and can produce a huge variety of motions. This section will build up your basic knowledge that will be utilised in section three to solve complex Mechanism Design tasks.

Section three is where the magic happens. This section is focused on the actual design process and how to approach design problems. The section is focused on Graphical Design Methods that are easily utilised using Fusion 360. By using Fusion 360 powerful sketching engine, complex Kinematic Diagrams can easily be simulated. You will learn how to solve two-position design problems like Crank-Slider and Crank-Rocker. Also you will learn how to solve three-position design problems in Fusion 360 by designing a material handling mechanism that carries boxes of a conveyor belt to a lower platform. This mini project will show you how to design a six-bar linkage that has one DOF to achieve a very specific motion. In each of these design problems, I will show you the method to solve the problem first then you will learn how to apply this method in Fusion 360. In Fusion 360 we will use the sketching constraints to construct geometrical relationships between sketch elements. It's exactly like using a pencil and paper but easier! This is followed by 3D Modelling the Mechanism and Animating it to check if the output is the required motion. All of this happens within Fusion 360 and the method I will show you is 100% parametric. This means you can go back to change the requirements and everything will update automatically to give you a new mechanism.

Who this course is for:

  • Anyone who like to design mechanical assemblies
  • Anyone fascinated with mechanisms and robotics
  • Those who wish to pursue a career in mechanical design
