You best use a robust design for ATV:
Front axle McPherson or double wishbone.
Rear axle: Dead axle and rear wheel drive.
For values (camber/toe, KnC values) just take a competitor vehicle which is good in driving dynamics and measure it.
Well.. first there shall be enough space for the so-designed suspensions to work... and then work on the suspension geometry as a function of body roll and suspension travel to determine the angles - camber, caster, KPI, etc.
A suspension system has three basic functions:
1 - Guide the motion of wheels to provide good steering kinematics.
2 - Control accelerations of vehicle body.
3 - Maintain optimum wheel/road contact.
The (front) suspension is a space mechanism (3dof) tobe opmised.
Depends upon 1. packaging (wheel enveloping thru the range of suspension travel), 2. suspension geometry and bushing selection to meet kinematics and compliance targets to achieve desired understeer, 3. ride stiffness and damping tuning to meet ride quality targets, 4. component sizing to meet durability requirements.
A. Singh Thanks for your addition... This work requires:
1 - Mechanism design in spatial kinematics.
2 - Mechanical vibrations applied theory
3 - Ride comfort criteria (ISO 2631)
4 - Engineering design work. "Adams"is not sufficient...
