Active creatures, such as humans, robots, and animals, are often at the heart of such animation and are required to interact in compelling and lifelike ways with their virtual environment. Physical simulation handles such interaction correctly, with a principled approach that adapts easily to different circumstances, changing environments, and unexpected disturbances. However, developing robust control strategies that result in natural motion of active creatures within physical simulation has proved to be a difficult problem. To address this issue, a new and ver- satile algorithm for the low-level control of animated characters has been developed and tested. It simplifies the process of creating control strategies by automatically ac- counting for many parameters of the simulation, including the physical properties of the creature and the contact forces between the creature and the virtual environment.

  • 7.6 Moments and Center of Mass in This Section We Want to find a Point on Which a Thin Plate of Any Given Shape Balances Horizontally As in Figure 7.6.1
    Arkansas Tech University MATH 2924: Calculus II Dr. Marcel B. Finan 7.6 Moments and Center of Mass In this section we want to find a point on which a thin plate of any given shape balances horizontally as in Figure 7.6.1. Figure 7.6.1 The center of mass is the so-called \balancing point" of an object (or sys- tem.) For example, when two children are sitting on a seesaw, the point at which the seesaw balances, i.e. becomes horizontal is the center of mass of the seesaw. Discrete Point Masses: One Dimensional Case Consider again the example of two children of mass m1 and m2 sitting on each side of a seesaw. It can be shown experimentally that the center of mass is a point P on the seesaw such that m1d1 = m2d2 where d1 and d2 are the distances from m1 and m2 to P respectively. See Figure 7.6.2. In order to generalize this concept, we introduce an x−axis with points m1 and m2 located at points with coordinates x1 and x2 with x1 < x2: Figure 7.6.2 1 Since P is the balancing point, we must have m1(x − x1) = m2(x2 − x): Solving for x we find m x + m x x = 1 1 2 2 : m1 + m2 The product mixi is called the moment of mi about the origin. The above result can be extended to a system with many points as follows: The center of mass of a system of n point-masses m1; m2; ··· ; mn located at x1; x2; ··· ; xn along the x−axis is given by the formula n X mixi i=1 Mo x = n = X m mi i=1 n X where the sum Mo = mixi is called the moment of the system about i=1 Pn the origin and m = i=1 mn is the total mass.

  • Simplified Tools and Methods for Chassis and Vehicle Dynamics Development for FSAE Vehicles
    Simplified Tools and Methods for Chassis and Vehicle Dynamics Development for FSAE Vehicles A thesis submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Master of Science in the School of Dynamic Systems of the College of Engineering and Applied Science by Fredrick Jabs B.A. University of Cincinnati June 2006 Committee Chair: Randall Allemang, Ph.D. Abstract 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.

  • Development of Vehicle Dynamics Tools for Motorsports
    AN ABSTRACT OF THE DISSERTATION OF Chris Patton for the degree of Doctor of Philosophy in Mechanical Engineering presented on February 7, 2013. Title: Development of Vehicle Dynamics Tools for Motorsports. Abstract approved: ______________________________________________________________________________ Robert K. Paasch 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.
