The paper addresses the issue of identifying the technical condition of rotating parts with by means of vibrodiagnostics. This method has been developing rapidly in recent years and it is conceived to be used for predicting failure occurrence. This enables us to determine an optimum time to perform machine preventive maintenance. The aim is to determine this point in time for groups of componen...
1. SOLID MODEL The main aim of the 3D design is to obtain a system that is very close to the real model considering the imposed functional conditions. In the machine tool design the parts are calculated for a proper strength and the stress level in each part is imposed to do not exceed material accepted values. A machine tool, particularly one that is used for drilling and boring processes (Fig...
This paper takes the large band sawing machine GB42500H as the research object, and establishes the dynamics models of its various parts. Respectively, the relative research is done from the theoretical modal analysis and the dynamic performance testing. According to the analysis results, the structure or geometry improvement scheme of the parts is proposed. The paper also studies preliminarily...
