Abstract： Distributed testing system has strong applicability in the field of dynamic testing, which can centrally manage the testing equipment in different locations through the local area network, and meet the new requirements of the test. Based on the theory of seismic location, the location of underground explosion center was studied. The applicability of seismic location theory to the location of underground explosion center was verified by simulating the underground explosion with LS-DYNA simulation platform. Combined with distributed testing system theory and weighting method, the optimal distribution method of test points was summarized through data analysis.
Key words： explosion center location； LS-DYNA； distributed testing system； seismic location； weighting method
