Evaluation Method of Freight Car Maintainability Indices
Abstract
With emergence of market relations and competitive environment there can be observed intensive market saturation with a great number of railway car products supplied by domestic and foreign manufactures. Newly designed cars vary in conception and employed materials. Such distinctions influence car maintainability indices. That’s why numerical values of these indices are of practical interest and can be used to solve such problems as determining the total life cycle costs of a car or assessing missed profit due to car idling in a maintenance depot. There is proposed experimental evaluation method of railway car maintainability indices based upon maintainability tests. Average car maintenance (repair) burden and average car maintenance (repair) time were adopted as basic indices. The paper describes main objectives and tasks of the maintainability tests, basic requirements to their organization/management and calculation procedure of the specified indices. The proposed evaluation method of railway car maintainability is of practical value since the obtained evaluation results may be of use in such applications as: setting scientifically grounded time and labour consumption standards to be applied to car maintenance and repair operations calculation of aggregated car reliability indices, such as availability, operational availability and utilization factors defining manufacturer’s warranty to customer with regard to maintenance and repair of railway cars and their element constituents
