Does motion ratio affect forces transmitted to the<br />
body?<br />
� L<br />
Force at spring for 1” wheel travel = 300 lb<br />
Force at body = Force at wheel / MR<br />
Spring Rate=300 lb / 0.5 = 600 lb/in<br />
Wheel Rate: 150 lb/in<br />
Spring Rate= Wheel Rate / MR 2<br />
Motion Ratio: 0.5 �Not good<br />
Force at wheel for 1” wheel<br />
travel = 150 lb<br />
Spring deflection for 1”<br />
wheel travel=0.5”
