What is the basic of cutting brake and it's working operation ?
Basics of Cutting Brake Cutting brakes are a system of levers, switches, or pedals that allow you to lock up individual brakes in order to stop one wheel and then use the other wheels to drive the vehicle, thus pivoting around that locked wheel. The result is a tremendously tight turning radius, and they can […]
Lateral and Tractive forces
Lateral forces This force (Fy) is acting on the tire centre which creates a moment, whose moment arm length is caster offset at ground. See fig. Lateral force depends on steer angle, cornering condition and with positive caster produces a moment attempting to steer the vehicle out of turn causing understeer. Net moment = ML […]
Analysis of vertical force in steering system
Condition for Ackerman- δo = tan-1 [L/(R+t/2)] δi = tan-1 [L/(R-t/2)] Error in steering Toe change- For an ideal steering system relay arm (tie rod) should follow the same arc as the suspension follows. Practically it is impossible to achieve due to nonlinearities in the motion of suspension. When the wheel moves in the jounce and rebound, […]
ANSYS Tutorials & Projects for BAJA-SAE
For proper analysis of your vehicle you need to conduct structural analysis of your cage for side, roll, front, rear & torsional impacts. The primary aim in your analysis should be to reduce weight of the vehicle and to test for failure.The un-sprung weight, rotating mass and roll cage are primary weight reduction areas and […]

ANSYS Classic – Mini BAJA Car Frame Exmple
The Society of Automotive Engineers sponsors the Mini Baja design competition as part of their collegiate design series. The purpose of the event is to have teams of engineering students design, build, and race a prototype of a four-wheel, one passenger, off-road vehicle intended for off-road recreation. North Dakota State University has participated in this […]
