Improvement for Dynamic Photoelastic Experimental Devices and Design for Construction of Charge
The multiple electric-spark dynamic photoelastic experimental devices are usually used in blasting research. It was originally designed far impact or small-caliber rifles shock load. So, it should be improved for part of dynamic photoelastic experimental devices after the devices were applied in blasting research. In the light of the property of high speed after explosive blew up, the greatness of transient dynamic loading, and the trait of some of explosive granules or specimens fragments exploded by explosive, the specimen loading system should be protected especially as well as the optical instrument on both sides of the specimen loading system. At the same time, one of the most difficult crucial technical issues is how to capture the isochromatic fringes in dynamic photoelastic blasting experiments. The issue is that the time of explosives blowup and electric-sparks discharge do not be controlled synchronously. In view of problems aforementioned, the method for blasting dynamic experiment is researched, a protective device is designed and a synchronous triggering device for construction of charge is devised in this paper. Several experiments showed good results with the protective device and the synchronous triggering device which saves cost of experiments even more makes experiments simply and feasibly.
