![]() ![]() In Genetic algorithm case, the optimality search was carried without the knowledge of modelling equations between inputs and outputs. Later this modeled equation was served as evaluation function or objective function for further process into genetic algorithm. For the Response surface methodology, an experimental design was chosen in order to order to obtain the proper modelling equation. Recently a new intelligent approach to the quarter car suspension system has been tried with response surface methodology and genetic algorithm which is new in the computational field. As the response surface methodology is a long established technique in optimization for experimental process. The simulation model was being achieved with the help of MATLAB/Simulink for further process to Genetic Algorithm through Response surface methodology modeled equation. This paper present on minimum value of rider comfortness vibration values to obtain maximum rider comfortness during riding. Ultimately, the proposed dynamic model of the dragster can be used to improve the aerodynamics, the engine and clutch set-ups of the vehicle, and possibly facilitate the redesign of the dragster. The results of the computational simulations are scrutinised by comparisons with data from actual dragster races. Several simulation runs are made to investigate the effects of the aerodynamics and of the engine's initial torque in the performance of the vehicle. The resulting nonlinear, coupled differential equations of motion are solved using a fourth-order Runge–Kutta numerical integration scheme. Further, a simplified model of the traction characteristics of the rear tyres is developed where the traction is calculated as a function of the slip ratio and the velocity. ![]() The aerodynamics of the vehicle, the engine characteristics, and the force due to the combustion gases are incorporated into the model. Longitudinal, vertical, and pitching chassis motions are considered, as well as drive-train dynamics. To analyse and eventually increase the performance of a top fuel dragster, a dynamic model of the vehicle is developed. The average power delivered by its engine exceeds 7000 Hp. This vehicle is capable of travelling a quarter mile in less than 4.5 s, reaching a final speed in excess of 330 miles per hour. The top fuel dragster is the fastest and quickest vehicle in drag racing. Basal on the results, it is shown that the four-link suspension, when applied to a drag racing motorcycle, does provide opportunity,for improving tractive effort at the beginning of a race which will improve overall drag racing performance. ![]() Parametric studies using dynamic theoretical models it-ere conducted,for both unsuspended and four-link equipped versions of the scone vehicle. Utilizing PC based CAD, finite element analysis and dynamic system analysis software, a motorcycle rear suspension system was designed, built and tested under actual racing conditions. This paper addresses the design of a four-link rear suspension for a drag racing motorcycle to provide anti-squat, which increases rear tire traction, thereby improving vehicle acceleration performance. Anti-squat is a transient vehicle suspension parameter which can dramatically affect tractive effort available at the motorcycle drive tire. ![]() In the drag racing environment, maximizing tractive effort is essential to competitive performance. ![]()
