Full-Scale Shell Impact Test of a DOT-105J500W Tank Car Designed to Carry Liquid Carbon Dioxide
FRA sponsored a full-scale shell impact test of a DOT-105 tank car designed for refrigerated liquid CO2 service. The tank car was filled to 95.2 percent with water and pressurized to 225 psig. The impact occurred at 15.5 mph with a 297,000-pound ram car equipped with a 12x12-inch impactor. The impact had a kinetic energy of approximately 2.4 million foot-pounds, and the tank car resisted the impact without puncturing. The pre-test model predicted puncture under the tested conditions. The shapes of the force versus displacement and pressure versus time responses from the pre-test model were generally in agreement with the test results.
