Finding velocity and acceleration in bicycle shock animation

[chandran]

Please go thro the link. it shows an animation of bicycle shox.

Suppose a person of weight 100kg sits on this how can i know the
velociy,accelerations at various points on the bicycle. Can any
basic dynamics theory help in this?

i may be wrong but you'd probably need the the spring constant ... use conservation of energy ... also need to know how the load is being transferred due the rotation ... i know I'm wrong but i gave it a shot

Don't we have a four bar mechanism there. If that is the case u can calculate the velocities and accln using the instantaneous centers method

burnhard,
Any website for showing method to find accelerations,velocity in four bar mechanism?

I am sorry I do not know of any good website which shows the methods to find accelerations and velocities in a Four bar linkage. Maybe someone out there can help.
