specific Embodiment approach 1
[0017] Specific implementation mode one: combine figure 1 , figure 2 , image 3 Describe this embodiment, a kind of method of this embodiment based on LS-DYNA to the layout optimization design of chemical industrial park storage tank area, specifically prepare according to the following steps:
[0018] Step 1. Select the storage tank area of the chemical industry park as the prototype of the numerical simulation, define the constraints of the selected storage tank area of the chemical industry park as the model parameters of the numerical simulation, and then the Hypermesh software generates a keyword k file, which contains the parameters of the storage tank area the modeling command;
[0019] Step 2: Input the parametric modeling command of the storage tank area contained in the keyword k file into the LS-DYNA software for solution, and obtain the d3plot result file through numerical simulation calculation;
[0020] Step 3. Use the LS-DYNA post-processor to post-proce...
specific Embodiment approach 2
[0022] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the constraint conditions of the storage tank area in the chemical industry park in step 1 are the size of the storage tank area, the size of the storage tank, the material of the storage tank, the medium of the storage tank, the energy of the explosion source, The distance and relative position between storage tanks.
[0023] Other steps and parameters are the same as those in Embodiment 1.
specific Embodiment approach 3
[0024] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the damage effect value of the storage tank area in the chemical industrial park described in step 3 in the whole explosion process includes the damage effect value when the storage tank area of the chemical industrial park exploded for the first time and the damage effect value that triggers the domino chain effect caused by the secondary explosion.
[0025] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.
