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...
Abstract It is widely accepted that stamping process planning for the strip layout is a key task in progressive die design. How- ever, stamping process planning is more of an art rather than a science. This is in spite of recent advances in...
Abstract A lathe attachment has been developed for an existing CNC machine (installed with rapid prototyping attachment) using conceptual design. The CNC machine operates on mechatronic controls and a computer interface called CAMSOFT, and...
INTRODUCTION Mathematical models of dynamic systems are required in most areas of scientific inquiry and take various forms, such as differential equations, state-space equations and transfer functions. The most widely used approach to math...
Abstract The effects of hot runner system on injection moulding process and properties of injected part have been investigated from various aspects in comparison with conventional runner system. A two-cavity mould which can be used for bot...
In this paper, the visual servoing problemis addressed by coupling nonlinear control theorywith a convenient representationof the visual information used by the robot. The visual representation, which is based on a linear camera model, is e...
