本文以4种不同工况的OTLC振动信号作为试验数据进行分析，4种不同工况

OTLC herein in four different conditions of vibration signals as a test data analysis, four different conditions as follows: normal contact, contact wear, and a contact off loose contacts, each group of 50 data acquisition conditions , each data of 6830 samples, from a random sample of 75% as training, as the 25% test.

In this paper, the OTLC vibration signal of 4 different operating conditions is analyzed as test data, 4 different operating conditions are: contact normal, contact burn loss, contact loose and contact shedding, 50 sets of data collected in each operating condition, each set of data for 6830 samples, randomly extracted 75% from the sample as training, 25% as a test.

In this paper, the OTLC vibration signals of four different working conditions are analyzed as test data. Four different working conditions are: contact normal, contact burning, contact loosening and contact falling off. Under each working condition, 50 groups of data are collected, each group of data is 6830 samples. 75% of the samples are randomly selected for training and 25% for testing.
