摘　　要：将测控技术与仪器专业基础课程“传感技术及应用”中谐振式传感器的优化设计与实际应用相结合,以谐振式加速度计为例,提出基于ANSYS的谐振式加速度计优化设计仿真与实验方案。实验内容包括:利用有限元分析软件对谐振式加速度计进行建模,分析结构参数对加速度计性能的影响,利用不同结构参数的模态仿真帮助学生直观理解优化设计过程。实验还对加速度计样件进行了实验测试,验证了优化设计方法的有效性。该优化设计方法还可应用于对其他类型传感器的优化。Combining the optimization and design of resonant sensors in the basic course "Sensing Technology and Applications" of measurement and control technology and instrumentation with practical applications,and taking resonant accelerometer as an example,the simulation and experiment scheme of resonant accelerometer optimization and design based on ANSYS is proposed.The experiments include modeling the resonant accelerometer with finite element analysis software,analyzing the influence of structural parameters on the accelerometer performance,and using modal simulations of different structural parameters to help students understand the optimization and design process intuitively.Experimental tests are also conducted on accelerometer sample to verify the effectiveness of the optimization and design method.The optimization and design method can also be applied to the optimization of other types of sensors.
