Performance test
Quasi-static reciprocating loading was performed on the test bench to test its yield displacement, yield force, ultimate deformation and other parameters. After the test, the damper was subjected to a 30-cycle low-cycle fatigue reciprocating loading test. First observe whether there is fracture or obvious damage, and then check the main design indicators. The error and attenuation of the test results should not exceed ±10% of the design value; if the test is passed, it can be determined that the damper of the same specification can be used in engineering installation, and the The damper used in the test is scrapped and archived.
