STUDY OF THE BEHAVIOUR FOR THE WORK EQUIPMENT OF A FORKLIFT DURING THE WORKING PROCESS USING FINITE ELEMENT ANALYSIS

Abstract

Industrial manipulators and robots play a very important role in the current process of advanced industrialization. The use of industrial robots has led to increased labor productivity, human replacement in hazardous work situations, increased product quality, rapid recovery of investment. Supple automation, the highest level of programmable automation, is organized into computer-driven production cells and serviced by one or more industrial robots. The transformation of production systems from the human-machine system to the human-robot-machine system has replaced the human in the process of performing dangerous or uncomfortable works. The diversity of definitions given to industrial robots and the lack of consensus on the notion of "industrial robot" is a premise for opening new horizons in trying to bring the machine closer to human perfection. The present paper aims to conduct a study of the behavior for the work equipment of a forklift during the work process. The tool used to conduct the study was finite element analysis using specialized Solid Edge software. A 3D model of the forklift's work equipment was introduced in Solid Edge and a dynamic analysis was performed, which led to the equipment's eigenmodes and eigenfrequencies. The displacement of the nodes of the structure in the first 10 eigenmodes of vibration and the potential deformation energy accumulated by the system were chosen for visualization, suggestive results and especially important for the specialists in the domain of construction equipments.
