STUDY THE EFFECT OF SHOT PEENING RESIDUAL STRESSES ON COMPRESSIVE STRENGTH OF STIFFENED PANEL

Autor: ZHANG ZiPeng, LIU Cun, YIN KaiJun

Publikováno v: Jixie qiangdu, Vol 42, Pp 492-498 (2020)

To determine the effects of shot peening on stiffened panel compressive strength,a typical shot peening residual stress was introduced by ABAQUS subroutine. Then,using temperature field equivalent method to transfer residual stress distribution to te

Autor: Yang Xiaobin, Wang Xiaoyao, Zhou Shilu, Zhang Zipeng

Publikováno v: 矿业科学学报, Vol 4, Iss 5, Pp 434-440 (2019)

In order to solve the problem of working face hypoxia in coal mine more effectively and reasonably, an improved general neural network (GRNN) model for prediction of oxygen concentration in coal mine was constructed, by taking the monitoring data of

Statics analysis model for rock burst of driving faces with stress inclusions

Autor: Yang Xiaobin, Zhou Jie, Zhang Zipeng

Publikováno v: 矿业科学学报, Vol 4, Iss 4, Pp 337-342 (2019)

Local dynamic phenomena or dynamic disasters such as rock burst often occur in the driving faces of underground rock roadway.In order to study its occurrence mechanism,based on the"locked in"stress hypothesis,a simplified mechanical model with a stre

A Nonlinear African Vulture Optimization Algorithm Combining Henon Chaotic Mapping Theory and Reverse Learning Competition Strategy

Autor: Wang, Baiyi, Zhang, Zipeng, Siarry, Patrick, Liu, Xinhua, Królczyk, Grzegorz, Hua, Dezheng, Brumercik, Frantisek, Li, Zhixiong

In order to alleviate the main shortcomings of the AVOA, a nonlinear African vulture optimization algorithm combining Henon chaotic mapping theory and reverse learning competition strategy (HWEAVOA) is proposed. Firstly, the Henon chaotic mapping the
