Abstract: This paper introduces the solidworks design flow, design methods and design principles of desk lamp. And we use the ergonomics principle, analysis the function of each part of the lamp, and analyses the design of lamp components, to meet user needs in the bedroom, do practical, human nature and convenient lamp. The application shows that the use of this software can make easier the realization of the design of the parts with complex shape, raise the design efficiency,optimize the product structure and save the cost.

Abstract: There are more and more complex tools and machinery that need be operated by human fingers in our modem industrial environment. Such as computer keyboards, screwdriver, handle wrench, button and switch. All of those should be designed to work effectively and safely with the operators for whom they were designed. At first, ergonomic consideration in design is reachable; this means the operators fingertip must be able to reach the operating component. This is generally no question because human arm has much more degrees of freedom required to position his arms, hands and fingers in the three-dimension space. However, some times we need the finger operate with a fixed wrist. For example in the case in the typing, the reachable workspace of the finger must take into account in such situation.Finger contacting is the most familiar operation mode of the man-machine system, and the index finger takes on the primary operation tasks. From viewpoint of ergonomic engineering, the operation component should be placed within the workspace of the fingertip to reduced or eliminate the movement of palm and arm should to the greatest extent during finger manipulation. Therefore the research of the workspace of ginger is significant to the ergonomic design of the operation device. In this paper, the reachable workspace and workspace under direction restrain of contacting for the index finger are determined using serial mechanism model and the Penalty Function Method based on geometric measurement of human body. The optimal operating position and orientation of human finger is analyzed.

Abstract: the system to DC voltage source as the core, AT89C52 MCU as the main controller, the output voltage to set the DC power supply through the keyboard, with a step function voltage to reality, the actual output value. This design is divided into four modules: SCM control and display module, digital to analog (D/A) conversion module, a constant voltage source module, output module. MCU control module as the core, the input signal is converted to digital quantity output; constant current source module voltage D/A conversion to analog conversion into constant pressure through a constant voltage circuit. The system has good reliability, high precision.

Abstract: Based on the linguistic Adaptation Theory of Jeff Verschueren, the Adaptation Principle explains the reasons of CS occurrence in terms of linguistic reality, social conventions, and psychological motivations. The present thesis applies the Adaptation Model based on manufacturing technology to the Chinese English CS of Chinese natives in online discourse. Based on the corpus of Chinese English CS in online discourse, the present thesis analyzes the CSs different forms, unique features and motivations of communications.

Abstract: This paper proposes a mobile robot design based on ant colony algorithm, aiming at how to achieve the optimization of path planning. Obstacle detecting and avoidance method for mobile robot are implemented with the photoelectric sensors. Then the ant colony algorithm for path planning is introduced and the simulation results in the software show that the method of introducing ant colony algorithm into mobile robot is convenient, feasible. By this means, the optimum problem is well resolved in real-time way during the running of mobile robot.
