Abstract

The article presents a calculation procedure for determining the maximum permissible load on the welded structure of the transport carriage. During the transport carriages operation inside the production hall there was no breakage of the welding joints. The use of carriages outside the hall and with an uneven surface began to create cracks and fractures in the weld joints. The values of vertical accelerations that were generated by running on uneven surfaces were determined by experimental measurement. To avoid cracks in welded joints, the maximum permissible load value of the transport carriage was subsequently determined by calculation using FEM.

Highlights

  • The purpose of the carriage is transport some various kinds of costs

  • We can see from the results of some experimental measurements that when the empty carriage went through the obstacle by the speed of 4–6 km·h-1 appeals on the construction additional acceleration in vertical way in the size ap = 14.735 m·s-2

  • The transport carriage has been designed to operate in the interior of the production hall

Summary

Introduction

The purpose of the carriage is transport some various kinds of costs. During use of the carriage in the exterior on the construction were started some deformations which are looked like a rift of welding joints. The carriage is pulling by the same standard electric tractor in the interior and in the exterior as well. Based on the request there were made some experimental measurements by using the carriage in the exterior [1, 2]. Their results were evaluated and they were used as an input data for the calculation by the Finite Element Method (FEM) [3]
