Numerical simulations on impact response of the support of gas generator

It is important for dynamic response analysis and parameter design to understand the shock environment of the support of gas generator. Numerical simulations for impact experiments of the support were investigated, and dynamic material parameters of the support were calibrated by use of LS-DYNA. Numerical calculations for parameters of loading properties were finished and validated by results of the actual trial run, which gets the peak value of pressure impulse. Numerical predictions for impact deformation of three types of the support under the validated pressure loadings were carried out. The improved design was presented to supply important references for parameter designs and practical tests of the support.
