MAKASLI BİR PLATFORM İÇİN YÜKSELME SÜRESİ VE HİDROLİK SİLİNDİR KUVVETİNE ETKİ EDEN TASARIM PARAMETRELERİNİN İNCELENMESİ
Abstract
Makaslı platformlar sahip oldukları basit mekanik yapısı ve üretim kolaylığı sebebiyle endüstride yaygın olarak kullanılmaktadır. Platform için gerek duyulan hidrolik kuvvet ve platformun yükselme süresi, tasarımda önemli faktörler arasında yer almaktadır. Bu çalışmada, platformun uzuv boyu, hidrolik silindirin mafsal konumları ve hidrolik hızı değişken parametreler olarak seçilmiştir. Parametreler için öngörülen farklı değerlerin platformun yükselme süresine ve platformda ihtiyaç duyulan hidrolik kuvvetine etkileri incelenmiştir. Ayrıca, parametre seçimlerinde hidrolik silindirin maksimum strok değeri bir tasarım sınırı olarak dikkate alınmıştır. Hidrolik kuvvet ifadesi hem Virtüel İşler Prensibi (VİP) hem de Virtüel Güçler Prensibi (VGP) ile elde edilerek statik ve dinamik hesaplar arasında oluşan farklar belirlenmiştir. Simülasyonlar sonucunda, farklı tasarım ölçüleri ve hidrolik hızları ile elde edilen sonuçlar karşılaştırılarak yükselme süresini ve hidrolik kuvveti minimize etmek için uygun geometri belirlenmiştir.

Investigation of Design Parameters Affecting Rise Time and Hydraulic Cylinder Force for Scissor Lifting Platform
Abstract
Scissor lifting platforms are widely used in industry due to their simple mechanical structure and ease of production. The hydraulic force required for the platform and the rise time of the platform are among the important factors in the design. In this study, the length of the scissor arms, the joint positions of the hydraulic cylinder and the hydraulic speed were chosen as variable parameters. The effects of different values assigned to the parameters on the rise time of the platform and the hydraulic force required on the platform were investigated. In addition, the maximum stroke value of the hydraulic cylinder is considered as a design limit in parameter selections. The hydraulic force expression was obtained with both the Virtual Works Principle (VWP) and the Virtual Power Principle (VPP). Differences between static and dynamic calculations have been determined. Thus, by comparing the results obtained with different design dimensions and hydraulic speeds, the appropriate geometry was determined to minimize the rise time and hydraulic force.
