Cylinder-crown integrated hydraulic press (CCIHP) is a new press structure. The hemispherical hydraulic cylinder also functions as a main portion of crown, which has lower weight and higher section modulus compared with the conventional hydraulic cylinder and press crown. As a result, the material strength capacity is better utilized. During the engineering design of cylinder-crown integrated structure, in order to increase the fatigue life, structural optimization on the basis of the adaptive macro genetic algorithms (AMGA) is first conducted to both reduce weight and decrease peak stress. It is shown that the magnitude of the maximum principal stress is decreased by 28.6%, and simultaneously the total weight is reduced by 4.4%. Subsequently, strain-controlled fatigue test is carried out, and the stress-strain hysteresis loops and cyclic hardening curve are obtained. Based on linear fit, the fatigue properties are calculated and used for the fatigue life prediction. It is shown that the predicted fatigue life is significantly increased from 157000 to 1070000 cycles after structural optimization. Finally, according to the optimization design, a 6300 kN CCIHP has been manufactured, and priority application has been also suggested.

某卵砾石地层浅埋公路隧道施工开挖,围岩的稳定性与拱顶沉降存在密切的关系,因此采用仿真分析法以拱顶沉降为控制目标,确保围岩的稳定,分析不同的施工方案得到拱顶沉降规律,达到优化施工的目的;同时,分析了不同的开挖路径和台阶长度,提出了一种最佳的施工方案。结果表明:在浅埋隧道开挖时容易引起拱顶沉降,并且随着施工方案的不同,拱顶沉降有较大的差异。在几种施工方法中,发现CRD法(交叉中隔墙法)比较适合,原因是拱顶沉降最小,应力释放较慢,在渐近的过程中有效地实现了应力的转移,较台阶法和CD法(中隔墙法)有大的优势,并与现场监测进行了对比分析,结果较为吻合。得到的结论可为类似工程提供参考。
