Repairing of piston rod in actuating cylinder of airplane undercarriage by brush electroplating 飞机起落架作动筒活塞杆的电刷镀修复
Mounted on the exterior undercarriage of vehicles , they can be removed in about a minute with any standard metal cutting tool 爬到汽车外底盘上，在一分钟内用任何规格的金属切割具都能把它拆下来。
There were at least two cases of soldiers being taken aloft hanging on to the undercarriage or tail wheel in desperation 至少有两机仓士兵被带上了天空，他们有的拼命抓住飞机的起落架，有的抱住尾轮。
According to an undercarriage loading system of an airplane , a linear model of an electrohydralic servo system was established and simulated 本论文以某型号飞机主起落架加载系统为例，首先建立了电液伺服系统的线性化模型并进行了仿真。
Then the horizontal load to aeroplane undercarriage tyre can be obtained more accurately by making use of the proposed model and results of drop - test simultaneously 根据起落架落震试验结果和该数学模型，可以得到考虑动态效应的起落架机轮水准载荷。
Wavelets technology and wavelet packages technology for the ultrasonic testing signal of some aeroengine . turbine vane and some aeroplane main undercarriage wheel - hub axes are researched 本文研究了某型航空发动机压气机叶片和某型飞机主起落架轮毂轴套超声检测信号的小波分析和小波包分析技术。
We specialized in manufacturing main kinds of undercarriage parts for excavator , bulldozer , such as track rollers , top rollers , idlers assy , sprockets , chain for komatsu , cat , hitachi , kato etc 我们专门制造各种主起落架零件,挖掘机,推土机,等径辊,胶辊,闲散总成,链轮,链小松,卡特彼勒,日立,加藤等
First , the basic working principles and veering theory of the structure with three wheels are introduced in this paper , and undercarriage framework is analyzed theoretically by the complex number vector 本文首先阐述了自动停车系统的基本工作原理和三轮转向结构的转向理论,并采用复数矢量的方法对仿起落架机构进行了几何尺寸的分析。
And then by analyzing topological structure of the system , three - dimensional model of virtual prototype is created by imitating the undercarriage . numerical analysis of system is made by numerical analysis software and virtual prototyping software , and dynamic model and numerical analysis results of the system are obtained 然后通过分析停车系统的拓扑结构,仿造起落架装置建立了系统虚拟样机的三维模型,并应用数值分析和虚拟样机软件对该模型进行了仿真分析,得出了系统的动力学模型和仿真结果。
