The subsurface crack propagation is one of the major interests for gear system research. The subsurface crack propagation lifetime is the number of cycles remaining for a spall to appear, which can be obtained through either stress intensity factor or accumulated plastic strain analysis. In this paper, the heavy loads are applied to the gear system. When choosing stress intensity factor, the high...
The response surface method (RSM) is applied in the parameter optimization of nonlinear stress control tubes in power cable terminations. A local approximation method, called moving least square method (MLSM), is adopted to reduce the approximation errors. The electric field intensity is calculated by the transient finite element method. A comparison of the parameters before and after optimization...
