The invention discloses a portable high-speed railway wheel track vibration time-space synchronization test method and system. The method comprises the step that a first data acquisitiondevice obtains a reflected signal when a high-speed train passes through a ground measurement point, and the relative position of the ground measurement point is generated according to the reflected signal; the first data acquisition device and a second data acquisition device perform clock verification; the second data acquisition device acquires a steel rail vibration response test signal when the high-speed train passes through the ground test point; the first data acquisition device acquires a vehicle vibration response test signal when the high-speed train passes through the ground test point; and a vibration response test device analyzes the wheel track vibration response according to the steel rail vibration response test signal and the vehicle vibration response test signal, and generates a wheel track vibration response report. According to the method, the corresponding vehicle vibration response when the train passes through a certain measuring point of the ground track can be accurately positioned.
