The invention relates to a portable vibration monitoring and maintenance system for a helicopter. The portable vibration monitoring and maintenance system comprises a sensor assembly arranged on the helicopter. The sensor assembly is connected with data collecting equipment through a signal line. The data collecting equipment transmits collected data information to data analysis and display equipment used for data processing. The portable vibration monitoring and maintenance system has the beneficial effects that the vibration of a rotor wing, an engine, a transmission shaft and a speed reducer of the helicopter is monitored for a long time through the sensor assembly, faults which may occur can be warned in advance, and a corresponding maintenance scheme can be worked out according to the detection result. The portable vibration monitoring and maintenance system is convenient to use, improves the flying reliability of the helicopter and guarantees the completeness of tasks.
