Based on this , presented a new micro pressure sensor , which adopted a si3n4 sensitive membrane ; since the membrane is very thin , we can use membrane - deflection theory to describe the deflection of the membrane under a uniformly applied load , and because with no bending stiffness , the sensitivity of the sensor was increased consequently . finally , numerical calculation of the deflection and stress analysis of the membrane was performed . by utilizing ansys simulation , we can testify that the performance of the sensor reached the design requirement 通过改进敏感元件结构,提高了其性能,从而得到适用于灵巧蒙皮表面压力测量应用的器件阵列:在此基础上,本文提出了一种新型的微型压力传感器结构,该结构采用的敏感膜片以氮化硅为材料,厚度较薄,因此该膜片的变形适用于薄膜变形理论的分析,忽略了弯曲应力的影响,从而提高了传感器的灵敏度。
It was found that the friction force reduced when the sliding velocity increased under a relatively low applied load . the friction properties of the aligned carbon nanotube film were very uniform in test region . the film on aao template had a considerable self - lubricating effect and the friction coefficient of the film was only 0 . 082 结果表明:多孔aao模板上的定向纳米碳管薄膜在干滑动条件下其摩擦力随滑动速度的增加而减小;多孔aao模板上的定向纳米碳管薄膜在大范围内具有相同的摩擦性能,其摩擦系数仅为0 . 082 。

In addition , the comparisons of displacements , velocities , solid effective stresses and pressure , obtained respectively by nonlinear model and linear model , display that the differences of the results become more obvious as the increase of the applied load , which demonstrates that the non - linear dependence of permeability on volume strain of solid phase is important as the deformation is not too small , and therefore cannot be ignored 此外,将本论文给出的非线性计算模型得到的位移、速度、固体有效应力和压力等与视渗透率为常数的线性模型的结果比较表明,载荷越大,两种模型的计算结果差异越大。而当载荷很小时,两模型的响应相差很小。说明在变形较大时,渗透率与固体相体积应变的依赖性不容忽视。
