Narrow Results

To solve the problem of a mining triaxial heavy-duty dump’s putting rod ruptures prematurely, When the dump in the bending and twisting conditions, the push rod’s static strength and stiffness was analysed by Hypermesh, and get the modals shapes and modal frequencies and generated a frame MNF file (modal neutral file) from the Ansys, established the rigid - flexible coupling model of the frame in ADAMS, get a load time history of fully loaded front and rear suspension. According to material fatigue properties’ S-N curve of the frame, using of MSC. Fatigue software the frame’s life was analyzed. The result showed the position of minimum fatigue life of frame is consistent to the position of abnormal rupture of putting rod in actual use; in order to improve the design of heavy-duty dump truck provides a reference.

With the advances in technology underpinning the design of armaments, unmanned combat platform has been developing rapidly in recent years. Using Finite Element Analysis (FEA) module of the SolidWorks software, Static and Model analysis could be performed by setting thickness of parts as variables, to study the stress distribution and natural frequencies, so as to obtain the optimal design, in terms of reliable performance for frame structural and lightweight frame.

For a cleaning frame with an engine, a loading and restraint scheme is proposed and the stress and deformation of the whole frame under low cycle rotation rate is analyzed, based on ANSYS software. The maximum stress and strain during the working process are obtained, and the variation rule for the maximum stress is discovered. According to the analysis result, the design for cleaning frame is optimized.
