THE USE OF ADDITIONAL DEVICES FOR REDUCING THE DEFORMATION OF THE BUS BODY WHEN TIPPING

The article is devoted to the solution of practical problems in the sphere of buses passive safety. Particularly, the methods of reducing bus body deformation when tipping due to reducing the height of fall of centre of gravity are worked out. The dependence of the distribution of impact energy for every stand of the left side of the bus body of LiAZ- 5256 from the length of sliding part of the piston rod device to prevent tipping is identified and investigated. The dependence of the displacement of every left cheek of bus body of LiAZ- 5256 from the length of retractable stem of suggested device is determined. The realized studies prove that devices like that the authors of the article offered are able to reduce the deformation of the pillars of the bus when while tipping. Thus, the greater is the length of the stroke of the device, the smaller is the amount of pillars movement in the direction of the residual space of the passenger compartment of the bus.
