A structural Optimization Design for Wear-out Life of Concrete Sealing

Abstract:

In order to solve the problem of lifetime of concrete sealing during the pumping process of concrete under the condition of multiphase fluid and variable load,this paper presents a design for structure parameters optimization of concrete sealing based on the homogenizing evaluation of the contact pressure of friction pair.That is to say,on the basis of the generalized physical model of elastic contact friction and wear,the paper analyzes the main elements which affect abrasion.Reference to the actual working conditions,this paper establishes the contact mechanical model of concrete sealing and carries out the multi-parameter optimization of the structure by Taguchi method.This study provides theoretical support for the design of concrete sealing under complex working conditions,and presents an engineering guide for reverse research of the similar contact wear damage.

Key words:concrete sealing; friction and wear; contact mechanics; structure optimization; Taguchi method
