Abstract:
As articulated steering and pitching device is the middle part which connects the front and rear truck of all-terrain articulated tracked carrier, which plays an important part in realizing the movements on the horizontal, vertical and torsional plane,also the structure of articulated steering and pitching device is very complex, and the theoretical formula calculation can not meet the requirements of overall structure analysis, so based on finite element theory, ANSYS software was used to make finite element analysis of the strength, stiffness and the capability of resistance to deformation and fracture in all parts of the articulated steering and pitching device to verify whether the design of the device is reasonable. Fifteen kinds of working conditions were selected as typical and dangerous ones used for analysis, and for each working condition different constraints and loads were chosen, also some special processing methods for model were taken, so as to simulate the real load working state. The results show that the design of the device is reasonable on the whole, but not perfect, and for some problems the device is redesigned with some improvement; the sample of all-terrain articulated tracked carrier is manufactured after being improved, and its running through the test ground shows that the analysis method is correct and proposed improvement for the device is reasonable. 1 tab, 13 figs, 9 refs.
