The invention relates to a sine strain generation device based on bi-piezoelectric ceramic push-pull driving and belongs to the field of strain capacity metering test technologies. The device comprises forked strain beams, a first piezoelectric vibrating table, a second piezoelectric vibrating table, a sine signal generator, a power amplifier, an inductance box, a tested strain sheet and a strainmeasuring instrument. According to the device, sine strain is generated in the way that the strain beams are subjected to push-pull driving based on the two PZT vibrating tables for generation of a sine strain signal waveform, and therefore the problem that the tension of the piezoelectric vibrating tables is far smaller than thrust is solved; and by using the two forked strain beams for loading,the problem that different piezoelectric vibrating tables are inconsistent in compression and stretching displacement is solved, and finally a high-frequency sine strain excitation waveform is obtained and used for performing metering and calibration on dynamic strain capacity values.
