Static strength and harmonic vibration analysis of the spider crane by computational mechanics software
(Altınbaş Üniversitesi, 2019) Sevdim, Tacetdin; Çalık, Orhan Koray; Baştürk, Süleyman
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.
