摘要
设计了一种二维微载荷传感器。用于仿生粘性材料的力学性能测试,也可用于一般的摩擦试验。利用应力集中原则对平行梁弹性体局部削弱,结合材料力学理论和有限元软件ANSYS对弹性体进行仿真设计。利用ANSYS后处理器中提供的路径映射技术,在弹性体应变最大的区域,确定弹性体应变计的最佳贴片位置。对传感器进行静态标定,得出其静态性能指标,其垂直方向的最大量程为3.0 N,分辨力为0.008 N;水平方向的最大量程为3.5 N,分辨力为0.01 N。
A special bidirectional force measuring sensor is designed for the experimentation of bionic adhesive material. The elastic body is weaken locally according to the principle of stress concentration, the parameters of the elastic body is gained by using the theory of material mechanics and the FEM program ANSYS, the best location to stick the strain gauge is found with the technique of mapping results onto a path which provided by ANSYS . Through calihrating the sensor,its static performance is got. Its measurement range for vertical force is 3.0 N with 0. 008 N distinguishability and measurement range for horizontal force is 3.5 N with 0. 01 N distinguishability.
