摘要
针对传统的不锈钢材质传感器外壳可塑性差且加工成本高的问题,通过研究SMC玻璃纤维环氧树脂复合材料的力学性能,按照等效刚度原则计算传感器外壳的壁厚,建立三维模型,并进行了静力学仿真分析验证。仿真分析结果表明:基于最大应变准则,采用SMC玻璃纤维环氧树脂复合材料设计的矿用NO_(2)传感器外壳能承受0.5 MPa的静压力,满足使用强度要求。
Aiming at the problems of poor plastic and high processing cost of traditional stainless steel sensor shell,through studying the mechanical properties of SMC glass fiber epoxy resin composite material,calculated the wall thickness of the sensor shell according to the principle of equivalent stiffness,established a three-dimensional model,and conducting static simulation analysis and verification.The simulation results show that based on the maximum strain criterion,the NO_(2) sensor shell designed with SMC glass fiber epoxy resin composite material can withstand a static pressure of 0.5 MPa,and meet the requirements of service strength.
