非侵入式翼伞组提带张力测量传感器的设计
Design of Non-invasive Tension Measurement Sensor for the Parachute Lifting Belt
摘要
Abstract
It is very important for the parachute study to master in the real time and measure safely and stably the tension of the parafoil group straps,as well as to explore the feedback relationship between the parafoil group straps tension and the parafoil posture.In order to solve the problems such as small range,complex structure and destruction of the structure of parafoil group straps,a large range tension sensor with two-arm beam side pressure was designed to measure the tension of the parafoil group straps,which is non-invasive,small in size,easy to install and disassemble.The sensor elastic body was designed by using SolidWorks,and the finite element simulation of the sensor elastic body was carried out by using ANSYS.Based on the analysis results,the structure of the sensor elastic body is adjusted and optimized,and the rationality of the sensor elastomer structure design is proved theoretically.A signal acquisition system with STM32 as the main control chip is designed to complete the functions of tension signal acquisition,data processing and data storage.A tensile machine was used to test the sensor performance,and the results showed that the designed tension sensor has high structural strength,high accuracy,good linearity and repeatability,which meets the demand for non-destructive measurement of the tension of the parachute lifting belt.关键词
