摘要： The present application provides a virtual reality-based derailment accident passenger comfort degree monitoring system and method, wherein the system comprises a train dynamics calculation module, a train operation state virtual simulation module, a six-degree-of-freedom motion platform, a train seat, a head-mounted display, a human body monitoring sensor system and a monitoring data storage terminal. The system establishes a database of the injury degrees of passengers with different ages under the train derailment; the test cost is low, the safety coefficient is high, and the repeatability of the test conditions is good, wherein the comfort degree test data of the passengers under the same derailment inducement can be repeatedly obtained; the safety risk in the actual test is eliminated, so that the authenticity of the test result is ensured, and the test cost is low and the repeatability is high.

摘要： A metro rail corrugation measurement method based the Seq2Seq model and vibration and noise data fusion comprises the following steps: Constructing a time series data set corresponding to floor longitudinal acceleration and train speed based on historical data of metro trains; Constructing the metro train mileage matching prediction model based on the Seq2Seq model, training the metro train mileage matching prediction model by time series data sets, and inputting the inside floor longitudinal acceleration of the metro train to be detected into the trained metro train mileage matching prediction model to obtain the running speed of the metro train to be detected. According to the vibration and noise data of the metro train to be detected, the vibration and noise composite index of the rail corrugation is calculated to determine the wavelength and amplitude information corresponding to the rail corrugation.
