In response to the problem of low output performance of traditional piezoelectric pumps,a force model of piezoelectric oscillators was established by analyzing the characteristics of circular piezoelectric oscillators.On this basis,the principle of system resonance was applied to successfully achieve unidirectional flow between fluids,resulting in the design of an inertial piezoelectric driven diaphragm pump.And use finite element simulation calculation method to simulate and analyze the design.The results show that the maximum output force of the inertial piezoelectric driven diaphragm pump is 52N,which is 10.63％higher than the maximum output force of the ordinary piezoelectric diaphragm pump of 47N.Overall,it can be seen that the design and analysis of an inertial piezoelectric driven diaphragm pump based on finite element simulation calculation have effectively improved output performance.
