The "research and demonstration of key technologies for ice flood monitoring and disaster prevention and control of the Yellow River" project has developed a light icebreaker for ice breaking operations in Baotou section of Inner Mongolia during the ice flood period of the Yellow River. On the morning of February 28, 2021, the researchers of the project team monitored the hull strain and acceleration under the ice load on the starboard side of the front of the hull during the ice breaking operation of the icebreaker in the river channel of Dengkou section of Baotou (40.5501110.1967 to 40.5512110.1812). This data set is the strain data of sensors 1-9 and the acceleration data of acceleration sensors 13-15 of the ice breaking hull from 9:58 to 10:40. This data is the original data of the ice load on the hull of the Yellow River icebreaker under the ice breaking operation for the first time, and has an important reference role for the study of ice load and hull strain during the opening period of the Yellow River.
The data in this data set are all sensor automatic monitoring data, and the monitoring time is from 9:58 to 10:40 on February 28, 2021; The river ice is 5-20cm thick and evenly distributed, with 50cm thick overlapping ice in some areas. Temperature (-5 ° ~ 1 °, north wind level 3). There are 12 sensors installed in the array on the starboard side of the forecastle of the icebreaker, and the numbers 1-9 are measured by the resistance strain gauge sensors arranged in the array; No. 13-15 is measured by three-way piezoelectric acceleration sensor. The sensor is connected to the portable computer through a transmission line. The strain and acceleration data are collected by Donghua test dh5921 dynamic stress-strain tester, which uses a low-pass filter with an upper limit frequency of 30 Hz to filter the noise signal, and the sampling frequency is set to 500 Hz. After sampling, the data is exported to.Xlsx format by Donghua test dh5921 dynamic stress-strain tester through a portable computer.
This data is the monitoring data, which is exported to.Xlsx format by Donghua test dh5921 dynamic stress-strain tester through a portable computer.
The monitoring data is automatically monitored by sensors. The instrument is reliable and the data quality is good.
