Abstract: The article is devoted to the assumptions and basic requirements that a technical condition monitoring system for a light rail vehicle should meet. The paper discusses the differences between classic and light rail vehicles and points out the impossibility of directly transferring railway experience to the operation of light rail vehicles such as trams. Furthermore, sample vibration characteristics from research on the dynamics of light rail vehicles under normal operating conditions are presented. These characteristics became the basis for defining the assumptions for building a system for monitoring the technical condition of the running gear and suspension of trams operated in Poland. The article concludes with findings regarding further work on building a system for monitoring the technical condition of trams under normal operating conditions.1. INTRODUCTION
The functioning of large urban centers is inextricably linked to facilitating the movement of residents, regardless of the reasons for the resulting transport needs or the methods of traversing space. Ensuring an efficiently operating public transport system in cities is a fundamental problem, on the solution of which their proper functioning depends. Improving the safety and reliability of vehicles – including trams – is one of the very important issues in the activities of public transport companies.
Most vehicle and track condition monitoring systems are used exclusively for classic rail vehicles. Meanwhile, the renaissance of tram communication in Europe and around the world means that tram lines are returning to favor, and trams are carrying an increasing number of passengers year by year. In this aspect, frequent monitoring of the technical condition of a light rail vehicle and the tram track has a significant impact on the proper planning of the transport process and reducing the costs of maintaining rolling stock and infrastructure, which allows for their better, more efficient use [1].
