Optimizing the Glass Clamping of a Pyrolytic Oven

An appreciable 30 to 40% decrease in stresses

ABSTRACT

The aim of this study was to find the best quality glass-clamping system, through parametric model optimization, for a new pyrolytic self-cleaning oven by Indesit.

Like all pyrolytic self-cleaning ovens the pyrolysis process causes the oxidization of spills and dirt in the oven at temperatures of 450°to 500°C reducing them to ashes. This process produces a high thermal gradient which considerably deforms the glass and can cause ruptures.

The door structure of a pyrolytic oven is made of a triple-glass system, each one separated by an air wall in order to guarantee rapid heat dissipation and to respect the safety regulations that limit external glass temperature to 60°C.

 

"EnginSoft, whom we have known for a while as a supplier of CAE systems, has demonstrated great competence in helping us make optimal use of technology through training and direct consultancy on specific projects."

RecurDyn offers a dedicated toolkit to pre-process, solve and post-process problems involving flexible media

The final portion of the paper path of a laser printer has been studied using the Media Transport Toolkit to evaluate the influence of the corrugating roller which is used to corrugate the sheet to keep it straight before falling into the tray.
