FIELD: instrument making. ^ SUBSTANCE: invention relates to structural test equipment. Proposed test bench comprises base, ball striker, guide tube fixed on said base for said striker to move therein and furnished with two parallel vertical sections interconnected by knee, electromagnetic coils arranged consecutively on one vertical section of aforesaid tube to electromagnetically interact with aforesaid striker. It comprises also starter to successively excite coils, specimen active gripper to interact with striker, specimen passive gripper and limiter to constrict passive gripper displacement towards active gripper. Note here that the tube second vertical end accommodates additional electromagnetic coils to interact with passive gripper, connected with additional coils starter. Note also that active gripper is furnished with electromagnet to interact with striker. ^ EFFECT: increased volume of data due to testing at both contracting and expanding load pulses. ^ 1 dwg |
