Quasi-Static and Dynamic Response Characteristics of F-4 Bias-Ply and Radial-Belted Main Gear Tires

Category : Science

Pages : 46
Book Description
An investigation was conducted at Langley Research Center to determine the quasi-static and dynamic response characteristics of F-4 military fighter 30x11.5-14.5/26PR bias-ply and radial-belted main gear tires. Tire properties were measured by the application of vertical, lateral, and fore-and-aft loads. Mass moment-of-inertia data were also obtained. The results of the study include quasi-static load-deflection curves, free-vibration time-history plots, energy loss associated with hysteresis, stiffness and damping characteristics, footprint geometry, and inertia properties of each type of tire. The difference between bias-ply and radial-belted tire construction is given, as well as the advantages and disadvantages of each tire design. Three simple damping models representing viscous, structural, and Coulomb friction are presented and compared with the experimental data. The conclusions discussed contain a summary of test observations. Davis, Pamela A. Langley Research Center RTOP 505-63-10-02

Intellectual Property Rights, Development, and Catch Up
Author: Hiroyuki Odagiri
Publisher: Oxford University Press
ISBN: 0199574758
Category : Business & Economics
Languages : en
Pages : 464
Book Description
For most countries, economic development involves 'catching up' with leading countries. This needs more than physical assets and labour: it requires technological capabilities, educational attainment, entrepreneurship, and development of the necessary institutional infrastructure, including intellectual property rights, particularly patents.

Quasi-Static Viscoelasticity Loading Measurements of an Aircraft Tire
Author: Angela J. Mason
Publisher:
ISBN:
Category : Airplanes
Languages : en
Pages : 28
Book Description
Stair-step loading, cyclic loading, and long-term relaxation tests were performed on an aircraft tire to observe the quasi-static viscoelastic response of the tire. The data indicate that the tire continues to respond viscoelastically even after it has been softened by deformation. Load relaxation data from the stair-step test at the 15000-lb loading was fit to a monotonically decreasing Prony series.
