Effect Of Center Of Gravity Location On Optimum Performance Of Random Vibratory Vehicle Suspension, Daniel Mahar
Effect Of Center Of Gravity Location On Optimum Performance Of Random Vibratory Vehicle Suspension, Daniel Mahar
Theses
This study provides the analysis for the optimal design of a conventional vehicle suspension system, consisting of a sprung mass (vehicle body) and two unsprung masses (wheel frame), accentuated by the implementation of a damped absorber to the unsprung masses. Further, the effect of the c.g. (center of gravity) location of the vehicle body is investigated. A two dimensional, four degrees of freedom linear model is chosen. Randomly profiled terrain is assumed to impart hyperbolically distributed stationary vertical random displacements to the front and rear wheels. For generalization, nondimensional design parameters are selected. Criteria for optimization include the tire-terrain normal …
Analysis Of Compliant Pins Subjected To Plastic Deformation, Lincoln Miller
Analysis Of Compliant Pins Subjected To Plastic Deformation, Lincoln Miller
Theses
An experimental/numerical analysis of two types of compliant pins is presented: dynamic retention pins and cantilever pins. It is shown that there is a trade-off between the performances of both types of pins. For the same range of retention force, the cantilever pin, with a smaller stiffness, is more forgiving and gives a broader range of deflection. The dynamic retention pin is shown to be more reliable with time and replacement frequency, since it exhibits less plastic deformation for the same range of retention force.
