To take The CRH3 EMU bogie frame as the research object, aiming at the characteristic and mechanical performance of bogie frame, the 3D model of CRH3 bogie frame based on PRO/E are established. According to the standard TB/T 2368-2005 Motive power bogie frame structure strength tests, the load condition is defined. The strength analysis by finite element analysis software ANSYS are carried out in the bogie and single frame . The analysis results show that the maximum stress value of the selected node is less than the permissible stress in both cases, the strength analysis result of the bogie frame is more credible because the load processing is more close to the actual stress.

Structure Evaluation

A new bogie frame of Light-Rail Transit (LRT) is having its strength of structure verified with experimental static testing according to EN 13749 standards. Static testing of bogie frame structure of LRT is performed by using a combination of seven tensile and compression loads that comprise of operational loads (normal service) and over-loads (exceptional service). Measurement parameters of bogie frame are strain and deflection values. The strain and deflection values resulted at every step of the load test were measured and monitored to further be used as analytic data. This data is then compared to the stress data of finite element analysis to check its deviation value. Testing results show the maximum stress value is 81.48 MPa on operational load, meanwhile, for exceptional load case, maximum stress is 120.96 MPa and deflection value is 1.25 mm. The maximum stress value is still below yield strength of bogie frame material S 555J2 (y=355 MPa). According to testing data, structure of bogie frame LRT fulfill as the acceptance criteria.

This article analyses and proposes suitable approaches to improve frame structures in term of weight reduction for heavy-duty truck chassis frame in general and semi-trailer frame in particular. Specifically, this study focused on reducing the weight of frame side members, which makes up the primary mass of the vehicle chassis. Some variants of design to evaluate its efficiency and applicability on semi-trailer frame were proposed. The study explored maximum stress and deformation within the frame structure under static loading conditions using the integrated finite element analysis and multi-body simulation based on which some modified designs from the existing frame was proposed to reduce the weight of the chassis frames, including altering the main beam's material property, cross-section dimension, or lightening holes. The analysis results were presented in plots of the stress and deflection spectrum of the frame in numerical simulations. The proposed approaches were analysed and discussed to find out the appropriate improvement method for the heavy truck frame and the semi-trailer frame suitable for the truck manufacturers in Vietnam.

The importance of bogie fatigue in railway rolling stock has been recognized as a contributing factor in structural failure. A bogie frame designed for Taipei rapid transit systems is analysed in order to confirm the technical strength requirements for static and dynamic loadings. A numerical finite element analysis is utilized in view of the complex geometry, and detailed plots are also presented in this report to give a complete understanding of the behaviour of the bogie frame. The von Mises stresses are adopted as equivalent stresses in the static strength calculation while the principal stresses are adopted in fatigue strength evaluation. Material yield stress and modified Goodman diagrams showing the permissible stress ranges are used as failure criteria respectively for static and dynamic loadings. It is demonstrated that the static strength and fatigue strength of the bogie frame satisfy the strength requirements specified by Taipei rapid transit systems.

Then the static stress of pump wheel was analyzed with ANSYS. The detail processes were described in this paper. The results show that the blades of pump wheel is loaded by alternating forces, and the maximum stress, which is 64MPa, locates at the junction area of the blades and shell. And the coupling analyzed in this study meets the strength requirement.
