1. A virtual reality-based derailment accident passenger comfort degree monitoring system, comprising:
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;
wherein the train dynamics calculation module is configured for generating dynamic
response data of a train under a preset derailment condition and transmitting the
dynamic response data to the train operation state virtual simulation module;
the train operation state virtual simulation module is configured for converting
the dynamic response data into a control signal and transmitting the control signal to
the six-degree-of-freedom motion platform and generating a virtual scene of a derailment accident based on the dynamic response data;
the six-degree-of-freedom motion platform is connected with the train seat, and the six-degree-of-freedom motion platform outputs a simulation vibration to the train seat based on the control signal;
the train seat is configured for conducting the simulation vibration to a testee;
the head-mounted display is configured for outputting the virtual scene of the derailment accident to the testee;
the human body monitoring sensor system is configured for acquiring health index information of the testee in a simulation vibration process and transmitting the health index information to the monitoring data storage terminal.
