- 针对涡轮盘定心衬套的结构特点和各工况下的载荷形式,分析了它的失效模式。
The failure mode of turbine disk centering ring was analyzed based on its structure feature and all load forms. - 广泛的研究表明,屈服强度低、粗晶粒尺寸、冶金缺陷的存在是造成涡轮盘用高温合金早期失效的主要原因。
The wide range of investigations shown shut lower yield strength, coarse grain size and metallurgical flaws were the basic causes for the earlier failure of superalloy for turbine disk. - 应用根据这种方法所建立的锻件预成形设计原型系统,对FGH95合金涡轮盘锻件用坯料进行预成形设计,取得了令人满意的结果。
The preform for FGH95 turbine disk forging was designed by using the preform optimization prototype system developed by the authors, the obtained results were satisfied.
