The investigations were done also for passenger cars at operational loading and emergency impacts occurring at trains collision or a train ride into an obstacle. The vehicle and its loading features, intercar coupling devices work, and passive protection elements deformation are taken into account. Proposals for passenger car equipment by protection means at emergencies are developed on the results of the calculations made and tests carried out. Recommendations on the box-type sacrifice element rational parameters choice are developed. They should be fixed to the car-body frame and provide to be broken to absorb emergency impact energy, to reduce longitudinal forces acting to the vehicle structure, and to improve passengers safety at the accident Product Description popup.authors popup.nrat_date 2020-04-02 Close
