In order to the solve the technical problem that stable thrust feature measurement and dynamic thrust feature measurement cannot be realized simultaneously at present, the invention provides an attitude control engine quasi-dynamic thrust measurement and calibration integrated device. The device comprises a fixation frame, a mounting base, a sensor assembly, a switching assembly, a calibration assembly, a charge amplifier, a cylinder control system, an acquisition system and a data processing system. The switching assembly comprises a switching cylinder, a switching ring and a sensor pull rod,which are connected in sequence. One end of the switching ring is connected with a cylinder pull rod of the switching cylinder, and the other end of the switching ring is in movable sleeve connectionwith one end of the sensor pull rod. The other end of the sensor pull rod and a center column of a strain sensor are in threaded connection at the place of a center column threaded hole. The switching cylinder drives the switching ring to move to enable the switching ring and the sensor pull rod to be separated or tightened, thereby realizing switching between the strain sensor and a piezoelectric sensor, and realizing simultaneous measurement of stable and dynamic thrust features of an attitude control engine in the same measurement device.
