Abstract

Vibrations diagnostics and analysis in operator’s and passenger cabins of a suspended monorail

Highlights

  • A suspended monorail is one of the main means of auxiliary transportation in underground hard coal mines is

  • The analyses carried out, the results of which are given in the paper, were aimed at analysing the impact of the use of a flexible suspension of the operator's cabin and passenger cabin on the level of vibration acting on the operator and passengers

  • An extremely important aspect of the analysis is the ability to change the mechanical properties of the suspension system elements and the observation of the impact of these changes on the level of vibration affecting the human travelling in the suspended monorail

Summary

Introduction

A suspended monorail is one of the main means of auxiliary transportation in underground hard coal mines is. Innovations introduced in the design of suspended monorails are aimed at improving comfort, safety and increasing the permissible speed during transportation of people (Budniok et al, 2014; INESI, 2019; Tokarczyk, 2017; Zasadni et al, 2015; Lesiak and Brzeżański, 2018; Tokarczyk and Kania, 2016). Intensive work in this area is carried out within the INESI project coordinated by KOMAG (INESI, 2019; Pieczora and Suffner, 2017; Polnik, 2018). This is related to the resonance of each organ (Harazin, 2002; Kiełbasa et al, 2019; Kowalski, 2019; Szczepaniak and Kromulski, 2011; Koradecka, 1999; AlShabi et al, 2016; Issever et al, 2003)
