Study on Virtual Test Method of Shock Response Spectrum
This paper aims to meet the requirements of shock response spectrum test and impact strength design and analysis of the product,carry out finite element modeling and impact dynamics simulation analysis based on the horizontal pneumatic impact test bench,extract the time-domain response of the structure,and then obtain its response spectrum by combining the self-designed impact response spectrum calculation program to complete the virtual test system of impact response spectrum.The effect of different model parameters on the virtual test response spectrum is studied and analyzed.The method can simulate the test process of horizontal impact test bench reasonably and effectively,and predict the system shock response.
