The invention discloses a flaw detection and simulated test device and a flaw detection and simulated test system of a steel rail. The device comprises an emulation computer and a signal generation / data acquisition unit, wherein the emulation computer is connected with the signal generation / data acquisition unit; a steel rail flaw pattern is set by adopting fault feature points to simulate the steel rail with faults; when a simulated test is carried out, a locomotive speed signal is set and ultrasonic echo parameter data is sequentially generated according to the steel rail flaw pattern corresponding to a locomotive driving position and is transmitted to the signal generation / data acquisition unit; the signal generation / data acquisition unit is connected with an outer steel rail flaw detection system and is used for outputting the locomotive speed signal to the outer steel rail flaw detection system, an ultrasonic drive signal sent by the steel rail flaw detection system is received, and an ultrasonic echo simulated signal is sent back to the steel rail flaw detection system according to the ultrasonic echo parameter data transmitted by the emulation computer. With the adoption of the flaw detection and simulated test device and the flaw detection and simulated test system, the technical problems that a test room checking manner for the steel rail flaw detection system does not exist, the testing cost is high and the test is easily restricted by the environment in the prior art are solved; the working performance of the detection system can be checked any time and any where.
