The number of registered motorcycles in Slovenia is growing continuously. A fundamental weakness of the road restraint barriers in Europe is that they are developed and verified in accordance with the requirements of the EN 1317 standard for restraining and redirecting passenger cars, buses and heavy goods vehicles but not for motorcycles. This report presents the results of numerical simulations of the HYBRID III test dummy impact with the C-post of a safety barrier with improved HDPE (High Density Polyethylene) protection and safety barrier with and without spencer on motorcyclist lathe. For all models, the tests were performed with different initial test dummy positions with respect to the longitudinal axis of the barrier and different impact velocities. Comparisons were made of damage parameters of the human head, neck and torso. Based on the results of simulations, an application proposal is given for the use of particular form of protection in certain traffic situations.

COBISS.SI-ID: 17064219Traffic infrastructure such as traffic signs, traffic lights, roadside posts, etc. can possibly become dangerous, especially to vulnerable road users. The report compares the results of numerical simulations of the HYBRID III test dummy head and chest impact into a C-pillar of a steel safety barrier and a traffic sign with a 65 mm diameter and HDPE protection (High Density Polyethylene). The influence of the base material and the impact speed on the dummy damage parameters were investigated. Experimental impact tests and comparison with numerical results were used for model validation. It was found that HDPE protection reduces the value of the dummy injury criteria parameters up to a 30 km/h impact velocity.

COBISS.SI-ID: 16092187Within the framework of a doctoral thesis by a candidate Janez Blaž, in-depth analysis was performed of the organisation and connectivity of the public passenger transport (PPT). A system has been developed for management, optimization and control of the PPT which currently includes a detailed description of the methodology implemented for the collection and organization of data for PPT management as well as a model for experimental and numerical analysis of use of hybrid-drive or alternative powered vehicles fleet (COBIS-ID: 16455451, 16666139, 40462853, 16327707). The aforementioned work relates to the issues that Slovenia has not been able to find a proper solution to for a long time as well as to the issue of using alternative drive systems of PPT vehicles.

COBISS.SI-ID: 16455451The present invention relates to a heat device comprising at least one heat exchanger and at least one heat source and / or sink. The heat device according to the invention is designed as a combination of a first heat device based on the steam-compressor principle and containing a first heat transfer medium and a second heat device based on the elastocaloric principle and contains another heat transfer medium. Said heat devices have in common at least one deformable heat exchanger made of elastocaloric material.
