Upper Crossbeam of Free Forging Press Optimization in Order to Improve Mechanical Properties and Durability

Abstract

This paper deals with an analysis of the stress distribution in different design solutions of upper crossbeam of presses CKV type. Performed was design optimization in terms of minimum weight, maximum rigidity and uniformity of stress distribution in all sections. During optimization is considered the maximum force of technological operation upsetting. The performed optimization and reduction of the stress will improve the fatigue strength. It results also in increased lifetime. This whole process shows way of machine part design preparation.

Vibration Fatigue - Fem Analysis vs. Real Testing

“…The following synthetic Wohler curve (for the polished specimen) was designed in the nCode software ( Fig.6). [Neugebauer 1989], [Raz 2015] Figure 6. Wohler curve for the material DC01 (regular and modified)…”

Optimization of Main Parts of Heavy Duty CNC Machine Centre Using Topological Optimization

“…The goal of the optimization problem is often a maximization or minimization of the objective function, for example minimizing the weight or maximizing stiffness of the product [1], [2]. In order to find the optimal solution, the 'core' of the solution depending on a specific set of design variables must be expressed by a numerical value.…”

Temperature Monitoring During Forging Process

“…Clearances are too big in that case and accuracy of forging press is lower. [4] Forging machine are affected by following thermal influence: 1. The heat from the forged part (from the forging process) 2.…”
