Concept Design of a Double Wishbone Suspension in Fusion 360

This  is a project based course which revolves around the design of a Double wishbone suspension system which is the most common Front suspension configuration in passenger vehicles.

Suspension design is a critical activity in Vehicle product development and this course covers the design methodlogy and philosophy behind designing the system .

Topics covered:

• Basics of suspensions

• Basics of kinematics of a 4 bar linkage

• Construction of a double wishbone system

• The Design process and major activities

• Project walkthrough

  • How to decipher Vehicle specifications and start the design

  • Setting important points in 3D .

  • Locating the Wheel end

  • Locating and Designing Ball pins and pivots of suspension arms

  • Locating steering points

  • Locating Shock absorber points

  • Design of Upper control arm and considerations

  • Design of Lower control arm and considerations

• Design Calculations and Analyses

  • Ride frequency intro

  • Arriving Wheel centre rate and then Ride rate

  • Calculating the Ride frequency

  • Arriving at the Spring rate

  • Designing the spring and setting specifications

  • Setting specifications for the damper

  • Creating a paramteric sketch to simulate suspension articulation kinematics

  • Finding Roll centre location in Front view

  • Finding Roll stiffness from springs

  • Finding Caster, King pin inclination , scrub

  • Force analyses of suspension members

The course will develop a deep understanding of how to design suspension system and do the concept level analysis to set it up .

Who is it for ?

- Automotive engineers already in the field and want to learn the suspension design

- Engineering students

- Automotive enthusiasts with automotive engineering knowledge

This is a workshop/ practical course . The best learning is when you actually attempt to design as per the walkthrough.
