摘要
提出了一种基于微气囊结构的柔性三维力传感器,该传感器基于硅橡胶材料设计了一种柔性传力柱结构,其底部均匀分布5个微气囊,通过测量这些微气囊气压值的变化来实现三维力的检测。利用COMSOL Multiphysics有限元分析软件建立了该传感器的仿真模型,分析了传感器在受力后微气囊气压变化情况,并采用BP神经网络算法进行三维力解耦,结果表明该传感器能较好地完成三维力的检测。
A flexible three-dimensional force sensor based on the subminiature air chamber structure is proposed in this paper. The sensor has designed a flexible force transmission column based on the silicone rubber material. Five subminiature air chambers are evenly distributed at the bottom of the sensor. The three-dimensional force is detected by measuring the change of the pressure value of these subminiature air chambers. In this paper,we use Comsol Multiphysics finite element analysis software to establish the simulation model of the sensor and analyze the pressure value change of subminiature air chambers after the force is loaded. The BP neural network algorithm is used to decouple the three-dimensional forces. The results show that the sensor can complete the detection of three dimensional forces.
