Self-fluxing Fe-Cr-Ni-B-Si alloy prowders are laser clad on medium carbon steel substrate of dimensions 80×35×10mm〓. The investigation results of this clad layer are: micro-defects, micro-cavity and occluded forin substance, are the micro-cracks and crack resourses in clad layer; crack of coating propagates along the boundary of two kinds of eutectic sutructure; The included angle θ between the cracking direction and laser scanning direction in multitrack overlapping clad is smaller than that in one-track clad because of crack propagating along crystalline growth direction and crystalline direction in overlapping zone being different from it in one-track clad.

在调质态的45〓钢表面,采用预置粉末法进行FeCrNiBSi合金的多道搭接激光熔覆,对其熔覆层进行分析表明:多道搭接激光熔覆层裂纹扩展方向与激光扫描方向间的夹角θ与单道熔覆时相比明显变小,前者θ0°,后者θ角基本都为90°,这主要是因为多道搭接时,搭接区结晶方向发生了变化以及裂纹沿结晶方向扩展所致;激光熔覆层裂纹大多是以覆层与基材交界面的孔洞、熔覆层内不同方向共晶团间的显微缩孔、夹杂物的边界等三种显微缺陷作为裂纹源,并沿低熔点物相形成元素偏析造成弱化膜的共晶团界面扩展延伸。

The VCL method and the displacement method are used to calculate the Stress Intensity Factors of semi-elliptical surface crack at the root of pipe screws, on the basis of which a simplified calculating model for screws contact is put forward so as to analyse the fracture intensity for oil drill pipe screw coupling. For the semi-elliptical surface crack with different shape and deep ratio at the root of female and male screws and the corner of male flange, the SIF has been studied systemically under inter-pressure, tension, bend and torsion loads and the approximate formulas encluding the structure parameters of oil drill pipe screw coupling, deep ratio and the shape parameters of surface crack are developed.

对工程实际中的多种石油钻杆接头螺纹连接件,就公螺纹齿根、母螺纹齿根、公螺纹台阶转角处存在的不同形状、不同厚度比的半椭圆表面裂纹,在拉伸、内压、弯曲、扭转多种载荷作用下的应力强度因子作了系统研究,在大量有限元计算基础上,建立了包含接头结构参数、裂纹形状、厚度比在内的近似计算公式。

The rub-impact between rotor and stator often occurs because the rotor shaft stiffness decreases following the occurrence of the crack in the rotor shaft, and thus the coupling fault with rub-impact and crack is hackneyed fault type. Based on the nonlinear dynamical model of the cracked rotor-bearing system with rub-impact, the stability of the periodic motion and instability way were studied in unbalance-rotating speed plane and rotor/stator clearance- rotating speed plane and crack depth- rotating speed plane, and the main results were validated by the experiment.

转子轴承系统裂纹故障的出现会引起转子系统转静件之间碰摩故障的发生,因此裂纹碰摩耦合故障也是转子系统常见的故障类型,本文在裂纹碰摩耦合故障转子轴承系统的非线性动力学模型基础上,分析了系统在不平衡量-转速、碰摩间隙-转速、裂纹深度-转速等参数域内,周期运动的稳定性及其失稳规律,并用实验验证了主要理论结果。

The influence of thedifferent parameters, such as blank-holder condition, thickness of blank sheetand material pattern on the wrinkle and the crack is analyzed. FLD is used tojudge the crack on the multi-point forming process successfully. The predictionof crack accords with the experiment ones, which shows choosing the properparameters can eliminate or restrain the defects, and also benefits the MPFtechnique and the shaping analysis.

本文对使用弹性介质和无弹性介质的多点成形过程进行了对比,指出使用弹性介质时在满足成形精度的前提下可以明显改善工件的成形质量,并通过对不同厚度和弹性模量的弹性介质对压痕的抑制作用进行了对比分析,探讨了最佳的弹性介质参数。

First of all, the disappearance of the first ways that children play, in order to prevent the plug-ins, Sacred Mountains, basaltic island baby can not play, and change the book thief盗宝so long ago that effort deep the rabbit is also a book of the times not to the复返; followed by the old group is the temptation of the book, but a book of 500 gold box, but the probability is very low is not a person can not bear such a money-burning ways to write or keep it Niuniu Let the people; day 9:00 into the civil service exam that there is risk of re-testing of the baby to be low-level book, but then the 10 day to individuals, we will look at the system notice can be a dream; every day to open the box when the St. lightning thunder mountain beasts also do not live to battle each other to cover up, not necessarily to say the book, the event is a child, the gold is on the Kuba Montreal.

首先先说消失了的方法打宝宝,为了防止外挂,圣兽山,玄武岛打宝宝不出了,改盗宝贼出书了,这样,以前那种只要功夫深,兔子也出书的时代一去不复返了;其次老群书是很诱惑的,但500元宝一个书匣,而且很很很低的几率也不是随便一个人可以承受的,这么烧钱的方法还是留着那写牛牛的人吧;每天进去9点科举复试的人会有几率得到低级的宝宝书,不过每天就那么10来个人,我们就看着系统公告做梦就可以了;每天到开箱子的时候圣兽山上电闪雷鸣也掩盖不要住刀光剑影,再说了也不一定出书,万一是童子,是满地的金子就哭吧。
