This paper briefly analyzes the sealing mechanism of actuator reciprocating seal. Taking the O-ring in reciprocating seal as an example, the finite element model was established by ANSYS Workbench. O-ring working stress distribution and failure mechanism were studied with finite element analysis method. The equivalent stress, the shear stress, the contact stress and the friction stress, under different...
Edge drop is a widespread problem in cold rolling, which affects directly the size of strip side scrapping and reduces strip yield. To reduce it, the mechanism of edge drop is elaborated detailedly, and the elastic-plastic FEM model to develop with the software MARC simulates the rolling process on 4-high cold mill. The fact that the calculated results of rolling force are basically close to the measured...
For hydraulic excavators, functions and reliability are important technical indicators. Previous mechanism analyses using finite element (FE) method have produced some computational results with only modest accuracies. The present study investigates a working mechanism of an excavator in its entirety from a system-integration viewpoint. Based on comprehensive analysis of typical operating conditions...
The paper studies sheet metal forming process using finite element analysis for large elastic-plastic deformation, offering both theoretical and methodological contributions to the subject. Sheet bending process is simulated using finite element analysis software ANSYS. The springback phenomenon is examined in great details. Taking A3 sheet as a specimen, the analysis presents springback values in...
There are many hinge points in earth-machinery working mechanism. A reasonable gap between shaft and bushings is so important for the design of working mechanism design. This paper briefly analysed failure mechanism caused by irrationality selection on fitting gap between hinge shaft and bushings of earth-machinery, such as hydraulic excavator working equipment. A new calculate theory and method on...
