To ensure the safe use of single shear hydraulic lift platform for processing and manufacturing railway vehicles. This paper analyzes the use conditions of single shear hydraulic lift platform, and makes a contact nonlinear finite element analysis on various typical use conditions. The positions of parts subject to danger can be found out through the results of static strength analysis, which finds out the weaknesses and prejudges the failure trend of parts, and which provides guidance for prejudging the faults in actual production and can prevent occurrence of accidents.

Synchronous test platforms were built to test the dynamic stress and working device attitude. The dynamic stress spectrums of all the test points under a variety of common conditions were obtained. The digging gestures corresponding to the peak of the dynamic stress spectrums were found out and taken as the specified digging gestures for the calculation of the static stress. The static stress nephogram of working device under the specified digging gestures was calculated using traditional static strength analysis. By conducting statistical analysis on the ratio of dynamic stress and static stress of all the testing points. Then, the range of generalized dynamic factor of working device was obtained.

Simulation Results

It is frequently reported by customers that the lower-left and lower-right wheels in the load fork mechanism of a kind of forward-type stacker designed based on static strength analysis are abraded faster than expected. In this paper, we studied by means of kinetics analysis and simulations the forces applied on parts of the fork mechanism. The simulation results show that the maximum values of instantaneous forces during operations are much higher than those derived based static force analysis, and thus explained the reason of the above-mentioned abnormal abrasion. The results also mean that static force analysis is not suitable for part strength design. Instead, one shall adopt kinetics analysis to explore the instantaneous forces in design.

The paper presents results of an analysis conducted in order to determine a cause of an emergency state of a timber roof rafter framing of a central nave ceiling in a church. The article showed an assessment of the current technical conditions, a description of the diagnostic tests performed and the results of the static strength analysis. Based on that information, the causes of this emergency state are described as the consequence of contractor’s errors during the execution and significant derogations from the construction design. Moreover, an implementation of a repair programme in order to restore the full value in use of the building is recommended.

Background: As a key component of the rail transit vehicle, the railway bogie greatly affects the dynamic performance, reliability, and safety of the high-speed rail vehicle. In this paper, the structural strength of a typical trailer bogie frame is evaluated and its strength and dynamic requirements are verified. In addition, various patents on bogie structural strength have also been discussed in this paper. Objective: The study aimed to evaluate and verify the rationality of the bogie frame structure design with static strength and dynamic characteristics. Methods: A three-dimensional model of the trailer bogie frame was built by CATIA V5, and then, a finite element model of the frame was analyzed by ANSYS Workbench. Bogie frame loads, static strengths and dynamic characteristics of the frame under different conditions (straight, curve, braking and abnormal) were calculated based on its strength and design standards. Results: According to the requirement stress and dynamics standard, the maximum stress of the bogie frame was observed to be in the allowable stress value of the frame material, and the dynamic performance of the bogie model meets the design standards. Conclusion: The structural strength of the proposed bogie frame is reasonable, and the static strength and dynamic characteristics of the proposed bogie model are in accordance with the design requirements of the railway vehicle.
