The results show that the life of low cycle large strain fatigue N of nitinol is between 102 -104 cycles; The less the cycle strain, sheet thickness, wire diameter and range of strain angle are, the more the life of fatigue is. Heat treatment of nitinol pl...

结果表明：TiNi合金低周大变形疲劳寿命在102-104之间；板厚、丝径、形变角幅度愈小，寿命愈长；热处理制度对疲劳寿命有重大影响，采用热拉伸工艺和400-500℃回火，合金有较好综合性能；合金中杂质含量和成分组织均匀性对合金性能有着重要作用。

For improving the maneuver stability,safety and decreasing the tire wear,the combination of the optimization software,modefrontier and msc.adams,is applied to design the steering mechanism,with bottom angle of steering trapezoid,arm length,kingpins distance and axles distance as design parameters,transmit angle as constraint,minimum error between theoretical and practical steering angle as objective function,and simulated annealing as the optimization algorithm.

为了提高汽车操纵稳定性、安全性及减少轮胎磨损，将数值优化软件modefrontier同机械动力学仿真分析软件m sc.adam s集成，以转向梯形底角、转向臂长度、主销中心距和轴距为设计参数，传动角为约束，以转向时内轮实际转角与理论转角的误差最小为目标函数，采用模拟退火算法对转向机构进行最优化设计。

A robust mathematical design model based on the response surface method was established for steering trapezoid mechanism. In the model, movement precision during steering course was chosen as the objective function; kingpins distance, axles distance, trapezoid mechanism's bottom angle and steering arm length were defined as the design variables; minimum transmission angle and maximum angle error were considered as the restraint condition.

对于转向梯形机构，以转向过程的运动精度为目标函数，以主销中心距、轴距、转向梯形底角和转向梯形臂长度四个参数作为设计变量，以最小传动角及最大角度误差作为约束，建立了基于响应面方法的稳健设计数学模型。

The data of polymorphism information contents, effective number of alleles and heterozygosity indicated that, the genetic variation of Small-tailed Han sheep was the highest, Mongoha sheep was the second, Lanzhou large tailed sheep was the third, Tibet sheep was the fourth, Poll Dorset sheep was the lowest.

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。
