Designing for Reinforcement Load Sharing

摘要

ose design has been neglected as an engineering topic. Hose Technology, 2nd ed., Colin W. Evans, applied science publishers, Essex, England, 1979; has been cited as a design resource. Paper 1 makes a correction to the Evan’s design equation; and this paper extends the solution to indicate how to distribute equally those design loads throughout the reinforcement. Introduction: This paper documents how to resolve the tensile requirement for the reinforcement based on how many reinforcement ligaments are required to support those forces. Method/Approach: The article looks to the tensile test results for the selected reinforcement ligament and illustrates how the elongation of the reinforcement as related to the manufactured length of the reinforcement are related so that the pressure loads are equally shared. Conclusion: The paper concludes all of the reinforcements must be the same manufactured length for the hose reinforcement to uniformly distribute the reinforcement tension. All strand lengths in a multilayer hose must be the same length for proper load sharing.
