Abstract
In the present study, dimensional optimization of screw system elements, like shaft diameter, arm length and nut height, has been performed by tensile, torsional, and shear strength calculations via genetic algorithm. Genetic algorithm has been used to minimize the objective function work with the idea of natural selection. The volume of the designed screw device has been defined as the object function. The limit function is composed of the total stresses affecting the screw system. The algorithm was set up in this way, due to the fact that it relies on the principle of finding the best in a genetic process. Values of the variables within the limiting intervals ensure that the screw device has an optimum size.
Kurzfassung
In der diesem Beitrag zugrunde liegenden Studie wurde die dimensionale Optimierung von Schraubenelementen, wie dem Schaftdurchmesser, der Armlänge und der Mutternhöhe mittels Berechnung der Zug- Torsions- und Scherfestigkeit mittels der genetischen Algorithmen durchgeführt. Der genetische Algorithmus wurde verwendet, um die Minimierung der objektiven Funktion mittels natürlicher Selektion auszuführen. Hierzu wurde das Volumen der designten Schraubenanordnung als Objektfunktion definiert. Die Begrenzungsfunktion setzte sich aus den Gesamtspannungen, die das Schraubensystem beeinflussen, zusammen. Der Algorithmus wurde auf diese Weise aufgebaut, weil er sich auf das Prinzip der Bestenauslese in einem genetischen Prozess verlässt. Die variablen Werte innerhalb der Begrenzungsintervalle stellen sicher, dass die Schraubenanordnung eine optimale Größe hat.
