本文提出了一种电磁力补偿（EMC）称重传感器的机电一体化模型。该模型在ANSYS Mechanical APDL（R）中设计，由两个模块组成：称重传感器的机械性能由FEM模型表示。电子和电磁部分，包括一个位置指示器，控制器和电磁执行器，实现到模型作为一组微分方程，通过ANSYS参数化设计语言（APDL）。机械、电磁和控制器部件的优化可以使用该模型以及实验来执行，以确定整个系统对环境特性的变化的灵敏度，例如，支撑的刚度。
In this paper, a mechatronic model for an electromagnetic-force-compensated (EMC) load cell is presented. Designed in ANSYS Mechanical APDL (R), the model consists of two modules: the mechanical behaviour of the load cell is represented by a FEM model. The electronic and the electromagnetic parts, consisting of a position indicator, controller and electromagnetic actuator, are implemented into the model as a set of differential equations via ANSYS Parametric Design Language (APDL). Optimization of the mechanical, electromagnetic and controller components can be performed using this model, as well as experiments to determine the sensitivity of the complete system to changes of environmental properties, e.g., the stiffness of the support.
