Title  Explosive blast storage testing device design and simulation analysis
Abstract
Explosive blast storage testing device is easy to install and use,and plays an important role in the blast tests.The structural and mechanical response of storage testing device make a serious impact on reliability and accuracy due to the harsh blast site testing environment.The structural and mechanical response of storage testing device are studied from both theory and simulation.And the structure of the blast storage testing device is designed and optimized.
The mechanical structure of storage testing device is configured overall through analysis of blast propagation characteristics of the ground,the appearance of the circuit module size,structural strength,convenience of installation and other factors.The cover,the protective housing,the support seat,the additional ring,the support base and the mounting base are designed.
The cover size and the response characteristics of circuit board in the field of explosion is emulated by using the finite element method and ANSYS software. A finite element model of the cover is obtained.The diameter and the thickness of the cover in the explosive field are emulated and obtained. A finite element model of the circuit board is built,and the mechanical response result are obtained. A kind of rubber shock absorber is designed accordingly and the damping effects are obtained.
