Abstract

Abstract

Micro vibration control is one of the most important goals in the construction of ultraprecise and large-scale scientific facilities. In order to meet the requirements for micro vibration control in High Energy Photo Source (HEPS), Beijing, a 1-meter-thick reinforced concrete slab with a 3-meter-thick concrete layer has been cast. The paper presented a field test of an artificial frequency sweep test from 1 to 100 Hz after the completion of the main structure in HEPS. Based on the analysis of the obtained vibration signals in the time domain and frequency domain, an evaluation of the micro vibration level and the micro vibration control capacity of the slab was conducted. The results indicated that under the vibrator’s excitation from 1 to 100 Hz, the mass concrete slab of experimental hall performed well in micro vibration control.
