【 摘 要 】

The characteristics of detonation wave propagation in the PTFE is analyzed by explosive theory, this paper has simulated the process of detonation wave's propagation in PTFE by dynamics program, the detonation wave's attenuation law in PTFE was obtained. In order to verify the rationality of the theoretical analysis and numerical simulation results, the detonation wave pressures were measured by the technique of manganin piezoresistance in different thicknesses of PTFE. It can be seen from the research contents that the calculation results are in good agreement with the test results, which shows the scientificalness and reliability of the simulation model and calculation method. The research contents provide the necessary technical support for the metrological study of detonation pressure test.
