Describe how the broad subject of dynamics is applied to vehicles in vehicle dynamics. What skills does it require to conquer vehicle dynamics topics?

Solution

Dynamics of a rigid vehicle may be considered as motion of a rigid body with respect to a global coordinate frame. The principles of Newton and Euler equations of motion that describe the translational and rotational motion of a rigid body plays an important part in Vehicle dynamics.

Vehicle Dynamics is concerned with the movements of vehicles - automobiles, trucks, buses and special purpose vehicles on a road surface. The movements of interest are acceleraton and braking, ride and turning. Dynamics behaviour is determined by the forces imposed on the vehicle from the tyres, gravity and aerodynamics. The fundamental law from which most vehicle dynamics analysis begin is Newtons Second Law since it applies to both translational and rotational. Determining the axle loads on the vehicle is the most important step in analysis of acceleration and braking performance because the axle loads determine the tractive effort obtainable at each axle, affecting the acceleration, gradeability, maximum speed and drawbar effort. All these things can only be mistified with the understanding of Dynamics i.e. Kinematics and Kinectics of a point and particle.

It is evident that dynamics of dynamics of a vehicle is of crucial importance because on the impact on active safety; handling behaviour and comfort are closely related with the properties of vehicle dynamics. Vehicle Dynamics can be easily understood with the help of Longitudnal Dynamics, Vertical Dynamics and Lateral dynamics.

Longitudnal Dynamics discusses the process of acceleration and Braking. Key importance here is given to the total running resistance, demand and supply of power and the driving state. It also includes the powertrains and adaptive cruise control. Vertical Dynamics inculdes the concept of vibration and oscillations when the vehicle is running on a bumpy roads. Lateral Dynamics describes the handling behaviour of a vehicle during cornering. Important concepts such as slip, oversteer and understeer, camber and toe angles are part of lateral dynamics, basically it deals with the influence of wheel load on handling behaviour.

Today the Multi-Body System are most commonly used in the automotive industry. It deals withone or more rigid bodies which are interconnected by springs, joints and shock absorbers/dampers. For calculating the behaviour of MBS models concept of Dynamics is necessary to interpret or check the result of MBS.

Skills required to conquer the vehicle dynamics topics are basic understanding of Dynamics. One should have a better understanding of the Kinematics and Kinectics of a body because with the understanding of these topics one will have a command over the basics of Vehicle Dynamics which will be helpful in determining the weight tranfer in a vehicle from front to rear axle and vice versa, traction and braking performance of a vehicle and various loads acting on a body in motion. Today is the era of MECHATRONICS thus one should have a understanding of basic electronics because electronic stability control is another major part of vehicle dynamics and obvioulsy one should have a command over Automobile body Structure and its components such as powertrain, suspension, Gears etc because it will be helpful in understanding the Vehicle Dynamics by knowing these basic terms.
