Vehicle Ride 2

1.Calculate the following parameters for the front and rear suspension:

i.Sprung mass critical damping

ii.Unsprung mass critical damping

iii.Sprung mass initial damping coefficient

iv.Unsprung mass initial damping coefficient

v.Low speed compression damping coefficient

vi.High speed compression damping coefficient

vii.Low speed rebound damping coefficient

viii.High speed rebound damping coefficient

2.Using the information calculated above, come up with a force vs. velocity shock curve for the front and rear suspensions (velocity range = 0 to 500 mm/sec)

Use the following information

Don’t consider any frequency optimization for this exercise

Solutions :

i.Sprung mass critical damping

Front = 188.07 N-s/mm

Rear = 206.37 N-s/mm

ii.Unsprung mass critical damping

Front = 311.77 N-s/mm

Rear = 259.23 N-s/mm

iii.Sprung mass initial damping coefficient

Front = 131.65 N-s/mm

Rear = 144.46 N-s/mm

iv.Unsprung mass initial damping coefficient

Front = 62.35 N-s/mm

Rear = 51.85 N-s/mm

Rebound to Compression ratio is same for all speeds
