Case Study | Application of DS-50A Dynamic Strain Gauge in Structural Test
Release time: 2020-01-08
DS-50A is a multi-channel computer-controlled online measuring strain tester. A single host consists of 5 expansion channel unit card slots. Each expansion unit contains 10 measurement channels. A single host can expand up to 50 channels. . Its frequency response range is DC-100Hz, and the highest sampling frequency is 1kHz. At the same time, DS-50A can realize multiple units connected in series, and each two units can be connected by a dedicated cable with a length of 100m, which can be tested simultaneously to meet the test scenario of distributed distribution of multiple measuring points.
In order to study the mechanical properties of the fully welded beam-column joints of aluminum alloy frames under reciprocating load, a full-scale welded beam-column joint test model of full-scale aluminum alloy frames was made. The reciprocating loading test was performed using the MTS servo loading system, and DS was used. -50A dynamic strain acquisition instrument collects strain measurement points.
- Application 1: Experimental study on the mechanical properties of beam-column joints of fully welded aluminum alloy frames
In order to study the hysteretic performance of the constrained energy-dissipation node of prefabricated fabricated steel pipe, a full-scale constrained energy-dissipation node model of prefabricated prefabricated steel pipe was made. The low-cycle reciprocating test was conducted using the MTS (50t) electro-hydraulic servo loading system, and strain collection The system collects real-time strain.
- Application 2 : Hysteretic test of constrained energy-dissipating nodes of prefabricated fabricated steel pipes
