Management and Production Engineering Review

2019

Vol. 10, No. 2

25–-36

At present, the speed of production and its complexity increases with each passing year due to the shorter product life cycle and competition in the global market. This trend is also observed in the machine-building industry, therefore, in order to ensure the competitiveness of enterprises and reduce the cost of production, it is necessary to intensify production. This is especially true in the machining of complex parts that require a great number of setups, and technological equipment. The problem-oriented analysis of complex parts was carried out, the parts classification was structured and developed according to the design and technological features. This made it possible to offer advanced manufacturing processes for complex parts like levers, forks, and connecting rods. The flexible fixtures for specified complex parts were developed. The effectiveness of the proposed manufacturing processes, as compared with the typical ones, provides significant improvement in the production.

A research on lifting fork equipment of forklift trucks

This article presents a research, conducted by 3-D computer models and the finite element method (FEM), on the stressed state of fork lift arms of 12.5 kN, 20 kN and 30 kN lift capacities. The folded region of the fork has been proved as being inconsistent with the classical assumption of a curved beam of high curvature. Formulations are drawn and some suggestions are given regarding computation of parameters of that folded region.
