Detailed Puncture Analyses of Tank Cars: Analysis of Different Impactor Threats and Impact Conditions

There has been significant research in recent years to analyze and improve the impact behavior and puncture resistance of railroad tank cars. Much of this research has been performed using detailed nonlinear finite element analyses supported by full scale impact testing. This use of detailed...

Tank Car Thermal Analysis, Volume II: Technical Documentation Report for Analysis Program

The computer program AFFTAC is described. The program can be used to analyze the behavior of railroad tank cars when subjected to fire. It is designed to perform the analyses which are required to determine if a tank car meets the requirements of the Code of Federal Regulations, Title 49, Part 179...

Improved Source Location Using Sensor Arrays

The purpose of this research was to develop a sensor array capable of identifying the location of acoustic sources. The sensor array was constructed from a polymer known as PVDF. The array was created using an etching technique similar to that used for printed circuit boards. An amplifier was...

Railroad Tank Car Nondestructive Methods Evaluation

An evaluation of nondestructive testing (NDT) methods, authorized for use in replacing the current hydrostatic pressure test for qualification or re-qualification of railroad tank cars, has been performed by the Transportation Technology Center, Inc. (TTCI), a subsidiary of the Association of...

Effects Of Coupler Height Mismatch On The Structural Integrity Of Railroad Tank Car Stub Sills

This project evaluated the safety implications of coupler height mismatches on the integrity of railroad tank car stub sills, through a series of static and impact tests. The test car was a loaded tank car instrumented with strain gages at critical locations. Static tests consisted of squeeze...
