Method and device for testing and evaluating stability and comfort of rail transit vehicle

The invention discloses a method and a device for testing and evaluating the stability and comfort of a rail transit vehicle. The method comprises the following steps: S1, constructing a stability andcomfort evaluation model of the vehicle based on the adhesion utilization efficiency of the vehicle; S2, sending a control signal to a DCU of a to-be-tested vehicle to simulate and test the operationstate of the to-be-tested vehicle under the specified operation condition, and calculating the adhesion utilization efficiency of the to-be-tested vehicle according to the test data in the test process; and S3, calculating an evaluation value according to the steady comfort evaluation model by using the adhesion utilization efficiency obtained by testing, and evaluating the steady comfort of theto-be-tested vehicle according to the calculated evaluation value. The invention has the advantages that the implementation method is simple, the cost is low, the stability and comfort of the rail transit vehicle can be tested
