Abstract

Abstract

Dependence of tension in membranes on the corresponding ultrasonic velocity and effects of radial tensionP weft tension ratio on the test results of ultrasonic method were investigated. Standard curves were founded and a modificatory method was presented. Results show that membrane tensions can be conveniently determined by ultrasonic method with sufficient precision. The relative average deviations after modification can be reduced to 151.50% , or even less than 10% , which can fully meet the technical requirements of engineering testings.
