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 .
- Basics of suspensions
- Basics of kinematics of a 4 bar linkage
- Construction of a double wishbone system
- The Design process and major activities
- 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 parametric 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
