Design, analysis and optimization of a servo drive scissor lift mechanism

Öz

In this study, the design, static and dynamic analysis and size optimization of a servo driven scissor lift mechanism for minimum energy consumption were investigated. In the study, the change of the starting angle according to the driving force is calculated with the help of the principle of virtual works and the principle of virtual forces in the case of lifting with the help of a screw shaft system instead of the classical hydraulic system. The necessary velocity and acceleration relations of the platform and the bars were found with the help of two different cycle equations. In addition, it has been shown how the driving force of the mechanism changes in response to different speeds under selected sizes. Finally, the topology optimization of the mechanism bars was carried out and the analysis results were given. Thus, a lighter mechanism design was obtained.

Servo Tahrikli Bir Makaslı Kaldırma Mekanizmasının Tasarımı, Analizi ve Optimizasyonu

Öz

Bu çalışmada, minimum enerji sarfiyatı için bir servo tahrikli makaslı kaldırma mekanizmasının tasarımı, statik ve dinamik analizi ile boyut optimizasyonu incelenmiştir. Çalışmada klasik hidrolik sistem yerine vidalı mil sistemi yardımı ile kaldırma işlemi gerçekleştirilmesi durumunda başlangıç açısının tahrik kuvvetine göre değişimi virtuel işler prensibi ve virtüel güçler prensibi yardımıyla hesaplanmıştır. Platforma ve çubuklara ait gerekli hız ve ivme bağıntıları iki farklı çevrim denklemi yardımıyla bulunmuştur. Ayrıca mekanizmanın seçilen büyüklükler altında farklı hızlara karşılık tahrik kuvvetinin nasıl değiştiği gösterilmiştir. Son olarak mekanizma çubuklarının topoloji optimizasyonu ile boşaltılma yapılmış ve analiz sonuçları verilmiştir. Böylece daha hafif bir mekanizma tasarımı elde edilmiştir.
