In order to obtain an intensified tearing effect of the multiple tear bomb at different launch-angle

based on the description of the composition and rupture principle of the multiple tear bomb

trajectory simulation of tear bomb was carried out by the software MATLAB/Simulink

the altitude curves and rupture-elevations was obtained.Combined the date of ball firing with the simulation result

the fumy phenomenon and the effect on crowd with the separate of bullet was analyzed.Though changing fumy time and using the method of weighted meant that optimized the Rupture-time

which could be assured the nonlethal and obtained an intensified tearing effect effect of the multiple tear bomb at different launch-angle

improved its combat effectiveness.
