Description
Technical field
The invention belongs to blasting explosive granules carefully to see stochastic modeling method, and in particular to a kind of blasting explosive granules meso-mechanical model is built at random
Mould method.
Background technology
The most typical material property of explosive is exactly explosion property, and the mechanism that detonation reaction occurs for causing explosive for people is ground
Study carefully and never stops.With deepening continuously for research level, it is important that people gradually have found that microscopical structure has explosive detonation characteristic
It influences.Cause the characteristic dimension range for the key position that many non-ideal constraints are lighted a fire between micron order scale.Due to fried
The inflammable and explosive hazard property of drug material carries out research risk height by test method and process is difficult to control, therefore imitative
True method becomes one of the reliable method that research explosive carefully sees reaction rule.
Explosive is typically to light a fire when by the extraneous thermostimulation of certain magnitude and force effect.Based on finite element numerical
Computational methods have been able to accurately emulate Thermal-mechanical Coupling effect.One of the key link for carrying out simulation study is according to reality
Border creates computation model.For explosive carefully sees particle, the diameter of individual particle and position arrangement are one typical random
Process, and numerous aggregates meet certain statistical regularity together.And it can be according to its position when explosive macromodeling
It sets coordinate and accurately sets up corresponding descriptive model.Explosive carefully sees granular model and differs markedly from Macroscopic Process.Therefore using normal
Rule modeling method cannot fully demonstrate the random law that explosive carefully sees particle.
Under normal circumstances explosive carefully see particle size distribution be located at it is a certain range of, quantity and position meet statistics
Regularity.It is then equivalent to according to conventional method modeling and introduces specific artificial tendentiousness, destroyed explosive and carefully see particle institute
The random law followed is bound to cause result of study and carries apparent tendentiousness, is not consistent with the natural law.
Chinese patent CN 201611078283.7 discloses a kind of PBX blasting explosive granules particle Random Discrete fill method, root
Script file is generated according to blasting explosive granules geometry data, and utilizes script file to PBX explosives using NairnMPM softwares
Grain pressing process carries out simulation calculating.But the particle radius that this method uses is not random distribution in a certain range, when
Grain radial span is bigger and when difference is smaller, is easy to cause filling and fails, and not specified population proportion, be easy to cause
Particles filled compaction rate generates bounce.
Therefore, it is necessary to invent a kind of blasting explosive granules meso-mechanical model stochastic modeling method, fully demonstrates blasting explosive granules and carefully see and divide
The random law of cloth provides valuable help for the igniting simulation study of meso-scale blasting explosive granules.
Invention content
In view of the deficienciess of the prior art, the present invention provides a kind of blasting explosive granules meso-mechanical model stochastic modeling method, use
Explosive to realize carefully sees stochastic modeling.
In order to realize that above-mentioned target, the present invention take the following technical solution：
The present invention relates to a kind of blasting explosive granules meso-mechanical model stochastic modeling method, progress explosive is carefully seen particle two-dimensional random and is built
Mould, which is characterized in that the blasting explosive granules meso-mechanical model stochastic modeling method includes the following steps：
