Notes
Lateral acceleration (ay)
Vehicles are under the effect of lateral force while passing the curve. The wind would increase the force to generate lateral acceleration.
ay ≤ 0.4 g
Lateral force coefficient (CS)
The equal lateral force on different vehicles has different degree of stability. The lateral force coefficient taking the total lateral momentum over the vertical momentum to evaluate the safety, stability, and comfort when vehicles driving on the curve. It is similar to the lateral force applied on the vehicle.
