“…This design philosophy is widely accepted by the Australian rail industry for rolling stock structures and is integral to international standards such as AAR M1001, Section C Part II [5] and BS 7608 [6]. Other similar/related methods are presented in [7][8][9][10][11][12][13][14][15]. The safe life philosophy -that structures be designed such that fatigue cracks will not develop within an acceptably low probability before the defined design life, is sound.…”

“…Extending our earlier works [8][9][10], in this paper, an integrated fatigue life and durability evaluation method based on multibody dynamics simulation (MBS) and finite element analysis for a locomotive car body is presented. A multi-disciplinary optimization algorithm is developed to handle the conflicting requirements of lightweight and good fatigue resistant car body structure designs.…”

In this paper, a multi-disciplinary analysis method is proposed for evaluating the fatigue life and durability of railway vehicle car body structure under random dynamic loads. The whole analysis involves the following steps: (1) Multibody dynamics Simulation (MBS) and Finite Element Analysis (FEA), which derives the load time histories for durability analysis, are performed to model the full vehicle complex system and simulate the rigid or flexible dynamic property of the car body. (2) Car body durability analysis involving a definition of the useful life and damage distribution of car body structure, including the stress or strain rainflow cycle counting, damage prediction, and remaining life estimation. (3) Multi-Disciplinary Optimization (MDO) method, an iterative procedure incorporated with several kinds of analysis results, is performed in a batch manner using some standard softwares, such as SIMPACK, ANSYS, FE-FATIGUE and modeFRONTIER. The methodology is also illustrated for handling conflicting problems of railway car body design for lightweight and fatigue requirements. Finally, the methodology and its detailed steps are discussed using a locomotive car body structure. A comparison of analysis results with experimental test results and the necessary car body structure fatigue design considering full vehicle dynamic property are also detailed. . 2009.
