description The invention provides a method for determining the connection rigidity of a rail transit converter and a vehicle body. The method comprises the following steps: 1, building a converter cabinet and vehicle body connection finite element model; step 2, verifying modal parameters of the converter cabinet body; step 3, establishing a kinetic model of connection between the converter cabinet and the vehicle body; step 4, setting an initial rigidity parameter k0 between the converter cabinet body and the vehicle body connection; step 5, performing a vibration test on the converter cabinet body to obtain test modal parameters; 6, performing finite element analysis on the converter cabinet body to obtain calculation modal parameters; step 7, comparing differences between the test modal parametersand the calculation modal parameters, and optimizing; and step 8, determining that the test modal parameter is consistent with the calculation modal parameter, and obtaining a final connection stiffness parameter of the conv
