Introduction With the process of industrialization, the manufacturing industry has been advancing The degree of automation is getting higher and higher. In the high temperature, dust, radioactive strong In the noisy production environment,...

Abstract. We describe further progress towards the development of a MAV (micro aerial vehicle) designed as an enabling tool to investigate aerial flocking. Our research focuses on the use of low cost off the shelf vehicles and sensors to en...

连杆在活塞往复式发动机内，连杆连接着装在曲柄或曲轴上的活塞。《巧妙的机械装置知识》一书这样写道：连杆发明于1174年至1200年的某个时候，当一个名为阿拉-贾扎里的穆斯林发明...

连杆的作用是将活塞承受的力传给曲轴，并使活塞的往复运动转变为曲轴的旋转运动。连杆由连杆体、连杆盖、连杆螺栓和连杆轴瓦等零件组成，连杆体与连杆盖分为连杆小头、杆身和...

ABSTRACT Metal shearing machines are heavy equipments usually linked to low added-value due to the small amount of technological devices incorporated. However, this situation can be changed through equipment designers creativity. Analysing...

Abstract: A tortuous labyrinth passage consists of a series of right angle turns in a disk of high pressure control valve. In this paper, numerical simulations are made for the velocity and pressure distributions in this passage. It is show...

Abstract: In traditional engine setups Belt Drive Systems (BDS) are in charge of power transmission from the crankshaft to the accessories. They are complex and critical dynamic mechanisms, involving contact mechanics and vibration phenomen...

THE DECISION BETWEEN WHICH antifriction bearing type to specify on National Electrical Manufacturers Associa- tion (NEMA) motors is not always easy or able for heavy belted loads (i.e., roller bearing), and the motor is directly connected,...

Abstract. In order to meet the demands of the welding of large scaled work- pieces, a welding robot is designed with 9 motion joints and 6 degrees of free- dom. Two groups of macro and micro motion mechanisms are adopted for large travel an...

在第一章我们知道,通常,一个测量系统由四种元件组成: 传感器,信号调理器,信号处理和 数据呈现元件.传感器是测量系统中的重要元件;它与所测量物体或系统接触并采取信号. 这是传感...
