Static Strength and Harmonic Vibration Analysis of the Spider Crane by Computational Mechanics Software

Year 2019, Volume: 3 Issue: 1, 35 - 50, 30.07.2019

Abstract

Abstract
In this study, it is aimed to investigate and perform the static structural and natural frequency analysis of the
mini spider crane which is designed to lift 0-500 kg load and 0-3 meters extend range, by using computational
mechanics software. The crane works and driven by hydraulic system and in order to get the more realistic
result, hydraulic cylinders modeled as springs instead of stiff rigid bodies in the analysis. This simulation
approach provides a different method than the conventional method. Detailed analysis show that the spider
crane statically can lift 1200 kg before the plastic region, so its safety factor is 2.4 when it is lifting 500 kg and
its natural frequencies are 16.2 Hz and 50 Hz.

Hesaplamalı Mekanik Yazılımıyla Örümcek Vincin Statik Mukavemet ve Harmonik Titreşim Analizlerinin Yapılması

Year 2019, Volume: 3 Issue: 1, 35 - 50, 30.07.2019

Abstract

Öz

Bu çalışmada, 0-3 metreden 0-500 kg yük kaldırmak üzere tasarlanmış bir mini örümcek vincin statik

yapısal ve doğal frekans analizlerinin araştırılması ve hesaplamalı mekanik yazılımı kullanılarak uygulanması

hedeflenmiştir. Hidrolik sistemle çalışan ve tahrik edilen vincin hidrolik silindirleri daha gerçekçi bir sonuç

almak için katı bir cisim yerine yay olarak modellenmiştir. Bu simülasyon yaklaşımı geleneksel metoda göre

farklı bir metot sağlamaktadır. Detaylı analizler sonucunda, örümcek vincin plastik bölgeye geçmeden en

fazla 1200 kg yük kaldırabileceği yani 500 kg yükte iken güvenlik katsayısının 2.4 olduğu, doğal frekansının

ise 16.2 Hz ve 50Hz olduğu saptanmıştır.
