An important part of the article is the results of simulation tests carried out for the developed model of a CWR track loaded with various values of longitudinal forces that may occur during operation. The forces act in the rail due to the occurrence of thermal stresses with values depending on the temperature change of the rail. In addition to simulation tests, the concept of experimental tests that will be performed on a selected section of the railway line is also presented. The MS-02 device will be used to measure longitudinal forces under various load conditions and to maintain the contactless path. The results of measurements made in the exploited track will be used in the long term to verify and further improve the numerical models.\u0000\u0000","PeriodicalId":150174,"journal":{"name":"WUT Journal of Transportation Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125885515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The training data were used for dynamic identification of the brake torque and the kinematic transmission ratio of the reduction gears. The testing data were used to check the accuracy of the model. The model has been implemented in the Matlab-Simulink environment. The energy efficiency characteristics of the lever drive wheelchair propulsion were presented as results of the work. The study includes the following research stages: (1) Execution of a series of measurements in the research environment, (2) Developing a nomnal and mathematical model of the stand (3) Identification of the model parameters (4) Implementation of the model in a programming environment (5) Model verification and validation (6) Carrying out the calculations of energy parameters including instantaneous efficiency and energetic efficiency of the work cycle.

The LCC analysis mustn’t generate more work than the benefits of it. Therefore appropriate assumptions should be made in constructing the method. The method assumes basic assumptions, taking into account the extensive scope of the research problem: transport infrastructure.

It was assumed that shipments are generated in the areas of address codes (more precisely: we know the volume of shipments between each pair of address codes in a time profile (day/week/month/year)). The problem of system structure optimization is decompressed into two subproblems: (1) location and dimensioning the company's branches by optimizing the number, location, bandwidth of branches and allocating code points to be serviced by the branches. The criterion for optimization is the total cost of establishing and maintaining branches and the costs of transporting shipments. From code points to the branch and vice versa; (2) location and dimensioning of the sorting plant and determination of the transport plan.

Provision of its appropriate value is crucial from the point of view of dynamic interactions occurring in a wheel-rail contact, what in turn translates into vehicle running behaviour and safety, passenger comfort, as well as further degradation of track condition. Track stiffness measurement is a cumbersome process requiring expensive equipment and can be carried out only if the line is closed. The following research is intended to estimate tram track vertical stiffness by means of vision method which can be performed during regular tram operation.
