摘　　要：电梯压力传感器是电梯测重系统的关键工作元件,利用有限元方法可以确定其结构的合理性以及贴片的合理位置,经过实验验证,测量得到的实验数据根据最小二乘法原理拟合的一元线性回归方程,不仅可以确定其线性度,而且可以对不同载荷范围之内的电压输出量进行预测。结果表明所设计的压力传感器线性度好,能满足使用要求。The elevator pressure transmitter is the elevator called the heavy-system the key work part,using the finite element method may determine its structure rationality as well as pastes the piece of the reasonable position.Confirming after the experiment,The survey obtains an empirical datum basis least squares method principle fitting Yuan equation of motion.Not only may determine its linear,moreover may carry on the forecasting in the different load scope voltage output.The result indicated that designs pressure transmitter linearity is good and can satisfy the operation requirements.
