Abstract
Recent investigations at DRDC Valcartier have focused on evaluating the use of an explosive charge inside a steel cavity (steel pot) to simulate loading of equipment due to detonation of buried anti-tank landmines. The current project focuses on assessing the ability of the Chinook CFD code to model blast loading generated by the steel pot configuration on a Specific Impulse Gauge (SIG) apparatus, and to perform parametric analysis of the loading distribution for different pot/explosive configurations. The current report details the numerical model validation completed under Task 1of the project and parametric analysis completed under Task 2. The original test configuration contains a round pot with 90º walls and a 5 kg cylindrical explosive charge level with the top of the pot. The SIG consists of a large steel plate containing several holes in which pistons (momentum gauges) of different masses are suspended.
