Optimal Design of an Off-Road Motorcycle Suspension
(The American Society of Mechanical Engineers (ASME), 1984)In this paper an optimal design is proposed which can be used by the suspension designer to maximize the performance of a given motorcycle suspension. The subject matter is developed by ... -
Improved Off-Road Tractor Ride via Passive Cab and Seat Suspensions
(The American Society of Mechanical Engineers (ASME), 1984)Low frequency terrain-induced vibrations transmitted to off-road vehicle operators are quite severe and exceed ISO specified “fatigue-decreased-proficiency” (FDP) limits. Ride improvement of an ... -
Elastic System Moving on an Elastically Supported Beam
(The American Society of Mechanical Engineers (ASME), 1984)The problem of a two-dimensional elastic system moving on a beam is considered. The moving elastic system or vehicle is represented by the structural members with distributed stiffness, damping, ... -
Identification of Vehicle and Collision Impact Parameters From Crash Tests
(The American Society of Mechanical Engineers (ASME), 1984)In the mid 1970s a group of 12 staged and instrumented automobile collisions was conducted for the National Highway Traffic Safety Administration. These were two-vehicle collisions with a variety ... -
Spectral Correlation Techniques Applied to Evaluate Noise and Safety Tradeoffs in Tire/Pavement Interaction
(The American Society of Mechanical Engineers (ASME), 1984)Relationships between pavement surface geometry, truck tire sound, and skid number are investigated to provide an understanding of the tire/pavement interaction mechanism. Correlation techniques are ... -
Control of Rapid Transit Propulsion System Noise
(The American Society of Mechanical Engineers (ASME), 1984)An extensive series of diagnostic measurements was carried out on an urban rail propulsion system of the type that was found to have the greatest community noise impact. At high speed, 3000 ... -
The Calculation of the Acoustical Quantities of Railway Wheels
(The American Society of Mechanical Engineers (ASME), 1984)The objective of the present investigation is to determine the forced vibrations and acoustical characteristics of a wheel disk with a radially varying thickness from the consideration of ... -
TRAXION: A Model for Predicting Dynamic Track Loads in Military Vehicles
(The American Society of Mechanical Engineers (ASME), 1984)This paper outlines a method that can be used to predict the dynamic track loads and suspension loads that occur in high-speed track vehicles. The presentation includes a description of the ... -
Coupling Technique of Rotor-Fuselage Dynamic Analysis
(The American Society of Mechanical Engineers (ASME), 1984)In this paper is introduced a method of dynamic analysis of the helicopter rotor coupled with fuselage in the rotating plane. The method has been used to determine the inplane rotor-fuselage ... -

NASTRAN Forced Vibration Analysis of Rotating Cyclic Structures
(The American Society of Mechanical Engineers (ASME), 1984)Theoretical aspects of a new capability developed and implemented in NASTRAN Level 17.7 to analyze forced vibration of a cyclic structure rotating about its axis of symmetry are presented. Fans, ... -
A Study of Unsteady Pressures Near the Tip of a Transonic Fan in Unstalled Supersonic Flutter
(The American Society of Mechanical Engineers (ASME), 1984)A comparison of experimental and theoretical results is presented for a modern transonic research fan, vibrating in a coupled flutter mode. The measurement of steady and unsteady pressures on ... -
Model Development and Statistical Investigation of Turbine Blade Mistuning
(The American Society of Mechanical Engineers (ASME), 1984)This paper discusses the development of an efficient algorithm which calculates the individual blade response of a bladed turbine disk, the subsequent statistical investigation to establish mistuning ... -
Vibrations of Twisted Rotating Blades
(The American Society of Mechanical Engineers (ASME), 1984)The literature dealing with vibrations of turbomachinery blades is voluminous, but the vast majority of it treats the blades as beams. In a previous paper a two-dimensional analytical procedure ... -
Maximum Resonant Response of Mistuned Bladed Disks
(The American Society of Mechanical Engineers (ASME), 1984)The turbomachinery bladed disks used in today’s advanced turbine engines must meet strict standards with regard to aeroelastic stability and forced resonant response. One structural characteristic ... -
Resonant Vibration Levels of a Mistuned Bladed Disk
