Impact-Echo signals generated by hammer with different tip and handle type

Dataset contains measurement of concrete test beam by a Impact-Echo technique. Test beam had diameter of 100 x 100 x 400 mm. Receiving sensor was in the middle of one 100 x 100 area and hammer was impacting the beam in the middle of other 100 x 100 mm area. Two different tips and handles of hammer were used and different force was used to generate signals. Each row of dataset contains type of used hammer tip, type of used handle, voltage of exciting impulse and three arrays - time of signals, signal from hammer sensor, signal from receiving sensor. Dataset is in Matlab .mat format, saved in Matlab2019b version. Sampling frequency was 193 kHZ.

本数据集包含采用冲击回波（Impact-Echo）技术开展的混凝土试梁测试数据。该试梁外形尺寸为100×100×400 mm。接收传感器布置于其中一个100×100 mm端面的中心位置，冲击锤则在另一块100×100 mm端面的中心位置对试梁进行冲击。实验中采用了两种不同的锤头与锤柄，并通过施加不同的冲击力以生成测试信号。数据集的每一行均包含以下信息：所用锤头类型、所用锤柄类型、激励脉冲电压，以及三组阵列数据：信号时间序列、锤力传感器采集信号、接收传感器采集信号。本数据集采用Matlab .mat格式存储，版本为Matlab 2019b。采样频率为193 kHz。
