DETERMINATION OF SHOCK WAVE FORCE IN SHOCK TUBE

Difference of 15 % in declared retardation time (time-delay) was determined during usage and testing of non-electric initializing system. Explosives Lab of Mining Geological & Oil Faculty in Zagreb University is performing testing with aim of design of detonator that would unify advantages of non-electric system and precision in regulating interval in electric system. Sum of energy released by wave force in shock tube is a condition for work of this new detonator, and measurement of wave force is first step in determining of sum of energy. Sum of energy is measured indirectly, on two principles: movement sensors and strain gauges sensors.
