1. Tsai, Der-Liang, 1958-. Kinematic and dynamic analyses of cascades of planar four-bar mechanisms .

Degree: 1988, University of Arizona

Computer programs have been developed for the kinematic and dynamic analyses of cascades of planar four-bar mechanisms. Since the analytic approach has high efficiency and accuracy in computation, a chain of four-bar linkages is developed horizontally and vertically by using the relative coordinates and the absolute coordinates, from which the explicit equations and the simultaneous equations are respectively derived in the kinematic analysis. In this analysis, the actions of transmission of linkages, from left to right, from right to left and from lower to upper, are performed by the image method and transformation procedures. Based on the kinematic analysis, the dynamic analysis is also developed by using both sets of coordinate systems. The generalized equation of motion, the general form of Lagrange's equations, Lagrange multipliers and the theorem of power balance are used to construct various formulations of the governing equations of motion for some particular problems. The problem of a linkage with a moving frame (the ground link) is the most interesting focus in this analysis. Advisors/Committee Members: Nikravesh, P. E (advisor).

2. Krishnasamy, Jayaraman, 1968-. A discretized contact patch to model tire-road interaction for vehicle dynamic simulation .

Degree: 1991, University of Arizona

This work deals with the problem of determining the tire-road interaction forces for vehicle dynamic simulations. The work is an attempt to develope a numerical scheme that is universally applicable to all possible running conditions. The tire-road contact patch is approximated as a two-dimensional array of nodal points. Properties such as distribution of normal pressure, deflection and stresses over the contact patch are expressed as sets of the respective nodal values rather than analytical functions. Such a representation enables the treatment of any arbitrary, two-dimensional variation of contact patch properties. The representation of non-rectangular contact patch shapes and trapezoidal pressure distributions is also discussed. For steady state running conditions the performance of the scheme is compared with that of an existing analytical model. The applicability of the scheme to transient running conditions is also shown. Advisors/Committee Members: Nikravesh, P. E (advisor).

3. Gim, Gwanghun. Vehicle dynamic simulation with a comprehensive model for pneumatic tires.

Degree: 1988, University of Arizona

This study presents an analytical approach for the mechanics of the pneumatic tires and the vehicle dynamic simulation. Most of tire dynamic parameters in this study are derived by using the tire geometry rather than experimental data. For the tire dynamic properties, explicit formulations are derived analytically as functions of slip ratio, slip angle, camber angle, and other tire dynamic parameters. These formulations can be efficiently used for the general vehicle simulations of braking/traction and steering maneuvers with a varying camber angle at irregular terrains. For on-highway vehicle simulations, a conceptual sports car is modeled as a twenty-six degrees of freedom multi-body system, while the military 1/4 ton truck M151-A2 is modeled as a fourteen degrees of freedom multi-body system for off-highway vehicle simulations. To study vehicle ride comfort, stability, and maneuverability, numerous vehicle simulations are performed using the comprehensive tire model, steering, braking, traction, nonlinear suspension, and realistic irregular terrains. For these simulations, a general-purpose multi-body dynamic analysis code (named MBOSS) has been developed. Advisors/Committee Members: Nikravesh, P. E (advisor), Vincent, T. L. (committeemember), Simon, B. R. (committeemember).
