Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, a group of vehicle dynamics simulation tools is developed with two primary goals: to accurately represent vehicle behavior and to provide insight that improves the understanding of vehicle performance. Three tools are developed that focus on tire modeling, vehicle modeling and lap time simulation. Tire modeling is based on Nondimensional Tire Theory, which is extended to provide a flexible model structure that allows arbitrary inputs to be included. For example, rim width is incorporated as a continuous variable in addition to vertical load, inclination angle and inflation pressure. Model order is determined statistically and only significant effects are included. The fitting process is shown to provide satisfactory fits while fit parameters clearly demonstrate characteristic behavior of the tire. To represent the behavior of a complete vehicle, a Nondimensional Tire Model is used, along with a three degree of freedom vehicle model, to create Milliken Moment Diagrams (MMD) at different speeds, longitudinal accelerations, and under various yaw rate conditions. In addition to the normal utility of MMDs for understanding vehicle performance, they are used to develop Limit Acceleration Surfaces that represent the longitudinal, lateral and yaw acceleration limits of the vehicle. Quasi-transient lap time simulation is developed that simulates the performance of a vehicle on a predetermined path based on the Limit Acceleration Surfaces described above. The method improves on the quasi-static simulation method by representing yaw dynamics and indicating the vehicle's stability and controllability over the lap. These improvements are accomplished while maintaining the simplicity and computational efficiency of the two degree of freedom method.

Download or read book Vehicle Dynamics and Control written by Rajesh Rajamani and published by Springer Science & Business Media. This book was released on 2011-12-23 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vehicle Dynamics and Control provides a comprehensive coverage of vehicle control systems and the dynamic models used in the development of these control systems. The control system applications covered in the book include cruise control, adaptive cruise control, ABS, automated lane keeping, automated highway systems, yaw stability control, engine control, passive, active and semi-active suspensions, tire-road friction coefficient estimation, rollover prevention, and hybrid electric vehicles. In developing the dynamic model for each application, an effort is made to both keep the model simple enough for control system design but at the same time rich enough to capture the essential features of the dynamics. A special effort has been made to explain the several different tire models commonly used in literature and to interpret them physically. In the second edition of the book, chapters on roll dynamics, rollover prevention and hybrid electric vehicles have been added, and the chapter on electronic stability control has been enhanced. The use of feedback control systems on automobiles is growing rapidly. This book is intended to serve as a useful resource to researchers who work on the development of such control systems, both in the automotive industry and at universities. The book can also serve as a textbook for a graduate level course on Vehicle Dynamics and Control.

Download or read book Simplified Tools and Methods for Chassis and Vehicle Dynamics Development for FSAE Vehicles written by Fredrick Jabs and published by . This book was released on 2012 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chassis and vehicle dynamics development is a demanding discipline within the FSAE team structure. Many fundamental quantities that are key to the vehicle's behavior are underdeveloped, undefined or not validated during the product lifecycle of the FSAE competition vehicle. Measurements and methods dealing with the yaw inertia, pitch inertia, roll inertia and tire forces of the vehicle were developed to more accurately quantify the vehicle parameter set. An air ride rotational platform was developed to quantify the yaw inertia of the vehicle. Due to the facilities available the air ride approach has advantages over the common trifilar pendulum method. The air ride necessitates the use of an elevated level table while the trifilar requires a large area and sufficient overhead structure to suspend the object. Although the air ride requires more rigorous computation to perform the second order polynomial fitment of the data, use of small angle approximation is avoided during the process. The rigid pendulum developed to measure both the pitch and roll inertia also satisfies the need to quantify the center of gravity location as part of the process. For the size of the objects being measured, cost and complexity were reduced by using wood for the platform, simple steel support structures and a knife edge pivot design. Via force balance methods, the addition of a known mass to the platform allows the computation of the center of gravity location. Measurement of the period of oscillation yields the respective inertia. Of note is the use of small angle approximations in the computation of the inertia; the magnitude of the oscillation should be kept minimal for best results. The newest, most relevant tire information available is only in a raw data format; for the design process this fact has been another barrier to integration. Data processing scripts were developed to organize the raw data and perform fittings to the PAC2002 tire model for steady state data; an expansion function for usage in Matlab was written to allow use of the coefficients in subsequent simulations. Estimations of the vertical spring rate and loaded radius of the tires were also developed. To quantify the transient thermal response of the tires, scripts to graph and analyze the data were prepared. Lastly, procedures for the estimation of the relaxation length properties of the tires from the raw data were executed to quantify the dynamic response of the tire's structure. With a working tire model that can be integrated in both Matlab and Adams simulations coupled with a full quantification of the vehicle's inertias, the capability to perform valuable chassis development and vehicle dynamics work is much more accessible.

Download or read book Development of an Intermediate DOF Vehicle Dynamics Model for Optimal Design Studies written by and published by . This book was released on 1910 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The demands imposed by the optimal design process form a unique set of criteriafor the development of a computational model for vehicle simulation. Due to the largenumber of simulations that must be performed to obtain an optimized design the modelmust be computationally efficient. A competing criterion is that the computational modelmust realistically model the vehicle. Current trends in vehicle simulation codes have tackled the problem of realism byconstructing elaborate full vehicle models containing dozens if not hundreds of distinctbodies. Each body in a model of this type is associated with six degrees of freedom. Numerous constraint equations are applied to the bodies to represent the physicalconnections. While the formulation of the equations is not particularly difficult, and in facthas been automated in several software packages, the resulting model requires aconsiderable amount of computational time to run. This makes the model unsuitable forthe application of computational optimal design techniques. Past research in the field of vehicle dynamics has produced numerouscomputational models which are small enough and fast enough to satisfy the speeddemands of the optimal design process. These models typically use less than a dozendegrees of freedom to model the vehicle. They do a good job of predicting the generalmotion of the vehicle and they are useful as design tools but they lack the accuracyrequired for optimal design. A model that bridges the gap between these two existing classes of models and issuitable for performing optimal design was developed. The model possesses twenty-eightdegrees of freedom and consists of eight bodies which represent the sprung mass, the rearsuspension, the left front spindle, the right front spindle, and the four wheels. A drivercontrol algorithm was developed which is capable of driving the car near its handlinglimits. The NCSU Legends race car was modeled and an attempt was made to optimizethe vehicle setup for the Kenley, NC.
