In order to find the reason of the fuze accessories failure and the fuze explosion

the severe environment with high acceleration and high pressure of powder in the bore was analyzed

a multi-dot

multi-axis and multi-parameter composite measurement method was proposed.A corresponded multichannel stored measuring system was designed and was used to test the different-direction stir signals produced by the fuze in the bore.The research indicates that the maximum axial load of the fuze suffering at the muzzle is 2 times higher than that in the bore

and simultaneously the peak radial load is 1.5 times higher.These data have exceeded the design standard of fuse

being the reason of fuze explosion.
