摘　　要：针对S型平行梁式电容称重传感器参数结构设计问题,运用有限元软件ANSYS Workbench对平行梁式弹性体结构进行参数化模拟仿真,基于二次多项式曲面拟合建立其结构力学性能与主要结构参数的函数关系,并通过算例分析验证了拟合公式的有效性。研究表明,拟合公式对复杂仿真计算后的结果有很好的近似,能更好的反应实际情况,公式结构更加简洁,具有较快的收敛速度、较高的精度和较好的推广能力,有利于准确实现平行梁式电容称重传感器结构参数设计。The formulas between main parameters of the structure and the structural mechanical properties were presented to solve the design problem of the structure of the S-type parallel beam type load cell capacitance,based on the results of the quadratic polynomial curve fitting,using the ANSYS Workbench software to do the parameterized-simulation of parallel beam elastomer. The effectiveness of the proposed formula is proved in the simulation example. This conclusion shows that the fitting formulas have very good approximation for complex simulation results and are of faster convergence speed,higher accuracy and better generalization ability. They can reflect the actual situation accurately and achieve better parameters design of the capacitance parallel beam load cell structural.
