Cycloid gear drive is widely used in robot cycloid planetary reducer, and the transmission accuracy key property of reducer. The standard a multi-tooth mesh. modification method has attracted extensive attention as one important parameters drive. influence isometric shifting on backlash was analysed according to characteristics mesh profile equation modified this study. Combined with analysis, multi-objective optimization mathematical model established ensure strength study showed that...
Based on the mechanical design loads and fatigue stress calculation method stated in code UIC510-5, strength behavior of wheel web for 32.5t axle-load heavy haul wagon was studied by using FE technology. The results at all nodes inside outside surface were calculated. show that maximum range dynamic stresses is 312MPa, its position located inner which radius about 310mm. It smaller than permissible 360MPa with unmachined web. Goodman limit diagram used assessing while considering effect mean...
Based on the microstructure change and damage characteristics of single crystal, a two-state-variable crystallographic creep constitutive model has been developed to investigate crack growth behaviors crystal compact tension specimen at 760 for two orientations: (001)[100] (011)[100]. Numerical simulation results show crack-tip stress fields are dependent orientation. Observations performed real specimens reveals that macroscopic path appears as zigzag wave. The deformation tip takes place...
The experiments and finite element simulations of composite laminate with stitching are carried out. Firstly, the monotonous tensile without conducted to investigate influence stitch reinforcement on laminate. Secondly, method (FEM) is employed simulate process specimens, link introduced stitching. experiment results shows that has little damage load under load, while there a significant changing strain. FEM consistent results, which means can be used study simulation also show distributions...
