摘 要：On the basis of the acceleration measurement of high impact,a high-g acceleration sensors of the piezoresistive beam-island structure at four-terminal all fixed supported was designed.Its structure was analyzed.The reasonable structure parameters were chose.And the parameter simulation and modal analysis were completed with ANSYS software.The results show that the sensor can resist 200,000 g overload and meet high impact test requirements.
