Application of Hooke's Theorem to Feedback Accuracy of Wind Pressure Sensor
Hooke's theorem is used to calculate the optimal value of the design of the wind pressure sensor:the thickness of the diaphragm is 58 mm,the spring line is 0.336 mm,the effective number of turns is 10,and the original length is about 14 mm.The experimental results of optimal values show that the accuracy of each feedback basically meets the design requirements,but the consistency is poor.In view of the above shortcomings,the innovative design of the shrapnel wind pressure sensor is applied to simulate the shrapnel with FreeCAD module.The analysis shows that the deformation of the shrapnel is uniform without local stress concentration,and the deformation of the shrapnel under the maximum force is far from reaching its limit.The innovative structure meets the theoretical requirements.It is found that the feedback accuracy of the shrapnel structure wind pressure sensor is consistent,and the feedback accuracy of each wind pressure monitoring point is close to the ideal value,which is superior to that of the spring structure.
