Analysis of Protective Effect of Epoxy Resin Under High Overload
In order to study the protective effect of epoxy resin on key components in the bomb body under high overload environment,Ls-dyna finite element software was used to simulate the impact overload of potting-sealing body of three heights under the same outer diameter under nine working conditions at three different speeds,so as to determine the transfer attenuation characteristics of stress waves in the height range.Select the height range with the least stress as the best height to place the board.The circuit board was added within the optimal height range to carry out shock overload simulation experiment on the whole potting group,analyze the stress distribution around the circuit board and the protective effect of potting glue on the circuit board,and then carry out shock overload experiment on the potting assembly through the impact test bench,the test results show that the circuit board is functional intact after being subjected to high overload.
