PERSHING TRANSPORTABILITY STUDY. CALCULATIONS AND ANALYSIS OF RAILWAY TESTS. VOLUME 1
Abstract
A stress analysis, based on the test loads imparted to the XM 475 and XM 476 containers in the CONUS railway impact tests, is presented in order to compare the structural adequacy of the two different types of restraining arrangements evaluated in the tests. Results of the stress analysis, which confirmed the test results, demonstrate that the restraining arrangement used on the XM 475 container is structurally adequate and meets the requirements of TB 55-100; whereas, the arrangement used on the XM 476 container is not structurally adequate and does not meet the requirements. Mathematical energy relationships were computed and used as a basis for comparing impact loads to the cargo in the CONUS and foreign railway tests. The impact calculations verify the test results which show that railcar impact loads to the cargo are more severe for foreign railcars than for CONUS railcars at similar impact velocities.
