摘要
基于ANSYS的应力分析功能进行压力传感器特性研究,用ANSYS数值计算方法分析了压力传感器的弹性平行梁。数值计算结果表明,压力传感器的节点位移与压力之间存在线性关系,说明在一定范围内,输出电压与被测物体的重量成正比,和实验结果一致。计算机仿真手段能够得到直观弹性平行梁应力云图,更可以用动画生动的应力作用实验过程和结果。一定程度上弥补了实验教学手段的不足,展示普通实验无法完成的实验内容,还可以清楚地知道电阻应变片应该固定的具体位置。
The characteristics of pressure sensor were studied by the function of stress analysis based on ANSYS,the elastic parallel beams of pressure sensor were analyzed using ANSYS numerical calculation method.The numerical nu-merical results show that there is a linear relation ship between the pressure sensor node displacement and the pressure,that is,in a certain range,the measured output voltage is directly proportional to the weight of objects,which agrees with the experimental results.The computer simulation...
