Hello Folks! I want to find the maximum applicable force on a full suspension mountain bike and i will use this force on a FEA software structural analysis for a uni design project. This bike has a rear suspension with 400 lbs/in spring rate.Also rear wheel vertical displacement(travel amount) is 120 mm.But i am confused about the assumptions. What will be the impact time?What is the weight distribution on wheels?Should i make the calculation solely on the bottom out position of rear suspension because stress will be maximum? I think i should make some manipulation on impulse momentum and kinetic energy equations. How can i calculate impact forces especially on the rear wheel?
