Loading force verifying method for rack eddy current dynamometer

The invention provides a loading force verifying method for a rack eddy current dynamometer, a signal processing system for a force sensor and a verification computer are additionally arranged on a chassis dynamometer of the existing rack eddy current dynamometer, the calculating loading force of the verification computer is taken as a truth value, and when a bigger error exists in the corresponding detected loading force relative to the loading force truth value, or a bigger error exists in the loading force truth value relative to the prescribed loading force, the verification detection is nonstandard or the equipment is in failure, so that the accuracy and authenticity of various performance detection loaded on the chassis dynamometer through the vehicle can be guaranteed, and the advantages of accuracy, simplicity, convenience, quickness and low price are realized.
