摘要 设计一种敏感单元为正四面体结构的三维柔性力传感器,对传感器进行受力分析,建立传感器单元受力的数学模型,利用有限元仿真验证上述分析过程的合理性,并通过试验系统对传感器进行标定和验证,测试结果利用BP神经网络进行解耦,结果表明该传感器能够实现0~11 N量程的三维力检测。 A sensing unit with a tetrahedron structure is designed as the three-dimensional flexible force sensing unit,the force of the sensor is analyzed and the mathematical model of the sensor unit force is established,then the finite element simulation is used to verify the rationality of the above derivation.The sensor is calibrated and proved by a designed experimental system,and test results are decoupled by BP neural network.The results show that the sensor can detect three-dimensional force of 0~11 N range.
