Анализ напряженного состояния изделий, получаемых методом ротационного формования

Анализ напряженного состояния изделий, получаемых методом ротационного формования

Abstract

В статье приведены основные направления использования компьютерной техники в промышленности переработки пластических масс. Особое внимание уделено применению компьютеров со специализированным программным обеспечением при ротационном формовании на стадии разработки формуемого изделия. В работе при помощи программы CosmosWorks 2006, базирующейся на методе конечных элементов, произведен анализ напряженного состояния изделий в процессе их эксплуатации. Анализировались как существующие, так и разрабатываемые конструкции изделий. В результате расчетов выбрана оптимальная конструкция изделия, которая может длительное время эксплуатироваться, так как напряжения, возникающие в этом изделии при его нагружении, значительно меньше прочности полимерного материала. Полученные результаты легли в основу конструирования оснастки для получения изделия «Бак топливный» в ОАО «Борисовский завод пластмассовых изделий».

The general directions of the use of computers in the plastics processing industry are resulted in the article. The special attention is given to the use of computers with the specialized software at the rotational molding during the stage of product design. The analysis of the stress state of the products during their exploitation is made in the work by using the program CosmosWorks 2006 which are based on the final elements method. Both existing and developed product’s designs were analyzed. As a result of calculations the optimal product’s design that can be used during long time because the stress in this part during exploitation is less then the strength of a polymeric material is selected. The received results have laid down in the basis of mold designing for producing part «fuel tank» on the «Borisov plant of plastic products».
