The Strength Simulation of a Predeformed Design of a Hatch Cover of Open Car

Abstract

To ensure the strength of the hatch cover of a general-purpose open car under operating conditions of the load, it is proposed to sheathe with a smooth sheet, which has a convex configuration and preload. The hatch cover rails are filled with a viscous substance having damping properties. The strength analysis of the improved design of the hatch cover is carried out for the main schemes of its load under operating conditions, as well as additional ones. The maximum equivalent stresses arising in the hatch cover of an improved design under operational load conditions have been determined. It is established that the strength of the hatch cover is ensured. The results of the research can be used in the designing of new-generation cars with improved technical, economic and operational indicators.
