Impact testing techniques based on electromagnetic loading were proposed to solve the problems of loading speed

loading force

safety problems and single mode of the existing impact testing technology. The accurate control of pulse width

amplitude and loading speed of pulse electromagnetic force can be realized by adjusting the power control parameters (mainly is capacitance and charging voltage) of electromagnetic driving impulse testing technology. The fast conversion of tension-compression test can be realized by changing the direction of electromagnetic loading head. In addition

as more and more attention has been paid to the testing of dynamic mechanical properties of materials under compound impact loads

multi-axis testing based on electromagnetic drive can accurately control the simultaneous discharge of multiple groups of capacitors through the control program，so as to ensure the synchronization of the isotropic impact load acting on the specimen material. Therefore

the testing technology based on electromagnetic loading has the advantages of good controllability

high repeatability

high synchronization of compound loading

high testing accuracy and experimental efficiency. The problems of traditional testing methods

such as small loading speed range

limited strain rate range and difficult impact testing with large loading force

are solved

and the safe

stable

reliable and more accurate control and measurement of impact testing experiment are realized.
