Investigation of strength conditions of the new wagon prototype type Zans

Abstract

The paper describe the most significant and innovative research and development design solutions and computational procedures as part of European structural funds project. The object of our calculations is strength simulation analyzes of a new structure of railway tank wagon for transportation of ignition matters through FEM analysis created in program MSC.Marc. Results of calculations and prototype tests prove, that new structure of the construction satisfies strength assessments according to valid requirements and standards.

Substantiation of Improvements for the Bearing Structure of an Open Car to Provide a Higher Security during Rail/Sea Transportation

“…The strength of the bearing structure of an improved Zans car with better technical and economic characteristics is determined in [1,2]. The strength calculation was made with the finite element method.…”

Optimization Procedure of Roller Elements Geometry with Regard to Durability of Spherical Roller Bearings

“…where: S is the probability of survival, N is the number of load cycles, V is the stressed volume, e, c, h, A are material constants defined by experiments, p 0 is the pressure present at the contact point, 2b is the minor axis of the ellipse [9]. Calculation of a total lifetime of the bearing was based on partial lifetimes of bearing rings.…”

Establishing patterns in determining the dynamics and strength of a covered freight car, which exhausted its resource

“…The research in [4] defines the main strength indicators of the load-bearing structure of the Zans-type freight car. The strength simulation involved the MSC.…”

“…However, the research does not specify the service life of these models of cars and the methodology for determining it. This may be due to that the studies [3,4] focused on the bearing structures of cars with nominal sizes.…”
