PBX9501

10 outputs, 7 inputs, 7000 observations. This data consists of simulated rate stick experiments for PBX 9501, a commonly-studied high explosive (HE), with various jacket materials. Rate stick experiments, or cylinder tests, are carried out by detonating a cylindrical stick of HE surrounded by a metal jacket. Photon Doppler velocimetry (PDV) diagnostics are used to measure the liner velocity at various axial locations to track the progress of the detonation. These 2D experiments were simulated using LANL’s free Lagrangian hydrodynamics (FLAG) code (Crowley (2005), Burton (2007)). For 14 different jacket materials (with fixed EoS, strength, damage and melt models), a rate stick experiment is performed for PBX 9501 under 500 different settings of the 6-dimensional JWL equation of state (Lee, Hornig, and Kury (1968)). The response includes the velocity and displacement of the jacket linear, as measured by the 5 PDV probes, 8 microseconds after detonation.

本数据集包含10个输出变量、7个输入变量，共计7000条观测样本。本数据集针对研究广泛的高爆炸药（high explosive, HE）PBX 9501，模拟了多种包覆层材料下的速率杆实验（rate stick experiment）。速率杆实验又称圆柱筒试验，具体操作为：将包覆有金属包覆层的高爆炸药圆柱杆起爆，以此开展实验。实验采用光子多普勒测速（Photon Doppler velocimetry, PDV）诊断系统，在多个轴向位置测量药型罩的速度，以追踪爆轰的传播进程。所有二维实验均通过美国洛斯阿拉莫斯国家实验室（Los Alamos National Laboratory, LANL）的开源拉格朗日流体动力学（Lagrangian hydrodynamics）代码FLAG（Crowley, 2005；Burton, 2007）完成仿真。针对14种包覆层材料（其状态方程（equation of state, EoS）、强度模型、损伤模型与熔融模型均固定），本数据集针对PBX 9501，在6维JWL状态方程（Lee、Hornig与Kury, 1968）的500种不同参数配置下，各开展了一次速率杆实验。实验结果包含起爆后8微秒时，由5个PDV探头测得的金属包覆层内衬的速度与位移数据。
