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.
