Regression Analysis of Strength of P-Type Membrane Based on Multivariate Statistical Analysis

Abstract:

In this paper， the specification parameters of 55 kinds of coated fabric membrane materials commonly used in engineering at home and abroad are counted， including warp and weft yarn density， fineness， grammage， thickness， etc.. The mechanical test results accumulated were sorted out， and data of the basic mechanical properties of coated fabric membrane materials were obtained. The multivariate statistical method was used to analyze the structure parameters and test results of coated fabric membrane materials， including the correlation analysis of mechanical properties and the influencing factors of mechanical properties. The influence of various parameters on these strength indexes of membrane materials was determined， and the further linear regression analysis was conducted. The regression models of tensile strength and tear strength were established respectively， which could be further applied to membrane material production and membrane structure design.
