THE EVALUATION OF THE DURABILITY OF A BATCH OF ELECTRICAL ENGINE STARTERS BASED ON A WEIBULL MODEL

This paper presents a method to evaluate the durability of a batch of electrical starters , fitted on buses used by the public transportation company of the municipality of Oradea. These starters have a short transient working regime, characterized by frequent start-stop usage, especially during the cold season. Based on statistical sample obtained from the exploitation documentation, it was proven that the temporal evolution of these starters is characterized by a Weibull model, but with a conspicuos tendincy towards the Rayleigh version - a distinctive model of equipments that have an operational regime characterized by strong attrition. Also, this paper analyzes the topic of acquiring this sort of equipments based on preliminary testing. These tests are meant to assess the probable durability level of these operational entities.
