Vibration Testing of Railroad Tank Car Specimens

Vibration tests of fireproof coatings were performed on test specimens measuring 4 feet square. Specimens were simulations of railroad tank car side- wall panels. Samples of fireproof coatings from three different manufacturers were tested. The vibration test consisted of application of a...

Vibration Test Requirements for a 70 Ton Boxcar: Revision 1

The Federal Railroad Administration is to perform a parallel effort of test and analysis of a 70 ton boxcar configuration. The program objectives are to develop and demonstrate a validation procedure, to provide an analytic capability of predicting accurate over-the-road boxcar response...

Vibration Level Data: Brighton-New York City Transit Authority

This report documents the results of a vibration measurement program conducted on 14-15 August 1980 in the Midwood Section of Brooklyn, New York, next to the tracks of the Brighton Line of the New York City Transit Authority. The test was conducted by the Transportation Systems Center (TSC) for the...

User's Manual for FRATX1 and FRATF1 Freight Car Dynamic Analysis Computer Programs

This is a user’s manual for two versions of a computer program to calculate the dynamic response of freight cars to track inputs. The basic program is nonlinear, written in FORTRAN for Control Data Corporation (CDC) computers with solution in the time domain by numerical integration methods. The...

User's Manual: SPAR 10 Structural Analysis, Finite Element Program, For Use on a DEC-2050 Computer System

The SPAR program, originally developed by W. D. Whetstone, is an analytical system for calculating static deflections and stresses, natural vibration modes and frequencies, and buckling loads and mode shapes associated with linear, finite element structural simulations. This Report extends the...

User's Guide: SPAR 11 Structural Analysis Finite Element Program (Including Graphics), For Use on a DEC-2050 Computer System

SPAR 11 is a version of Level 11 of the SPAR program, as modified and enhanced for the Association of American Railroads. The enhancements are in the area of interactive use and graphics on the DEC-2050 computer. This user's guide does not replace the SPAR Program Manual, but has instead the...

U. S. Transit Track Restraining Rail Volume I, Study of Requirements and Practices

This report covers a study of restraining rails in transit track made as part of the current research program of the Urban Mass Transportation Administration of the U.S. Department of transportation. The study was initiated to develop information to assist in the analysis, design, maintenance and...

Truck Design Optimization Project (TDOP) Phase II: Wear Data Collection Program Report

This program is part of the field studies conducted during the TDOP Phase II Project. TDOP is designed to examine the performance of various freight car truck designs with the objective of improving the efficiency and productivity of rail freight transportation. Maintenance and repair costs of...

Truck Design Optimization Project (TDOP) Phase II: Performance Characterization of Type I Freight Car Trucks

TDOP/Phase II is part of a series of studies being conducted by the FRA to define the engineering options available to the railroad industry to improve the efficiency and productivity of rail freight operations. As part of this effort, experimental and analytic studies have been conducted to define...

Truck Design Optimization Project (TDOP) Phase II: Guideline Test Specifications for Freight Car Trucks

Under the Federal Railroad Administration-sponsored Truck Design Optimization Project Phase II, a set of standard test specifications were developed to evaluate and characterize the performance of Type I (standard) and Type II (premium) freight car truck configurations. The test specifications...
