Abstract: Computer modal analysis is very helpful for the structural design process of the two-dimensional numerical control turntable, which is a complex opto-mechatronics equipment as a fixture used for the two-dimensional germanium drum under ultra-precision flycutting. The structure of the two-dimensional turntable designed here is modeled and analyzed in ANSYS for the computer modal analysis. The results are obtained by the modal analysis to ensure that the nature frequencies of the structure are different from the natural frequency of the motor turning to prevent the resonance occurrence. The work in this paper ensures the structural reliability of the two-dimensional turntable.

Abstract: wiring fault is a fault in the fault plane, along with the development of the aviation industry, increasing aging aircraft, how to use the manual fault and failure analysis, mature locomotive repair personnel each should master the basic skills of Boeing aircraft repair. combined with a specific fault, in conjunction with the relevant manuals, carries on the analysis to the wire and remove the fault.

Abstract: The paper introduces a kind of inverse distance weighted interpolation theoretical derivation and its solving way. The basic principle of this method is that to use known information limited data were interpolated to the unknown information for point, through the obtained interpolation point value to calculate the new interpolation point value. Thus, it is solved that the problem that limited number of temperature points can not be comprehensive description of temperature field, and the method is applied in the process of solving the unknown temperature points in the two dimensional temperature field. The characteristics of this method are simple, practical, less amount of calculation.

Abstract: Localization is a criticalissue for autonomous vehicle navigation. A localization model based on thestable response in lateral dynamics of the vehicle is hard for practicalapplication because of its nonlinearity, multidimensionality and multivariable.A dynamic self - adaptive network, which is able to adjust the scale of theparameters dynamically and has a good regression performance and self learningability, is used as a approximator to modeling the localization of the vehicle.In order to get a higher accuracy in modeling, a Kalman filer is designed forthe input signal such as steering angle and velocity. From the practicaltesting results on our vehicle, it’s indicated that the localization error is less than 1meter. So, the proposed method in this paper is a practicable and efficient onefor application.

Abstract: In the course of sampling, the self-adaptive approach to exposure time was adopted for increasing the sample precision of the linear CCD. The path recognition method was obtained in the light of proceeding posture of the smart car, and provided path parameters. According to the path parameters, the controller regulated simultaneously the left motor speed and the right motor speed by left motor driver and right motor driver respectively. The difference of the left motor speed and the right motor speed made the smart car go straight and turning, so the smart car realized the path recognition accurately.

Abstract: This paper introduces several methods of soft start of belt conveyor, Through the analysis of all kinds of soft start mode, the prospects of development of soft start device of belt conveyor, and through the comparison of several commonly used start speed curve, the reasonable start speed curve, pointed out the direction for the research of soft start device of belt conveyor.

Abstract: This article focuses on the tool setting methods and techniques of disk parts and hole parts , in order to improve the precision and efficiency of the tool setting, so as to improve NC milling machining quality and machining efficiency of Nc milling.

Abstract: This paper puts forward a complete track forecasting models, using Kalman filter to track and predict the movement of objects without prior knowledge. Use the extracted Harris corner to calculate optical flow between two frames by L-K pyramid method, getting the convex hull of moving objects by optical flow clustering to separate the moving objects from background. Tracking and predicting the gravity of moving objects convex hull can solve the occlusion and separation problem between moving objects. Computer simulation and field test results show that the proposed method has higher tracking accuracy, and small amount of calculation.

Abstract: The structural layout and basic principle of a four-coordinate CNC device mounted on a common CNC milling machine was introduced, with it four-coordinate workpieces can be machined by a single setup,which can reduce costs and improve efficiency.

Abstract: This article will extracte biological EEG information, extracted by EEG brain-computer interaction module. It has taken advantage of brain-computer interaction techniques, accurately extracted EEG data, modeling the data, analyzed EEG law, and the signal is used in Bluetooth smart car.The human brain with computers and external communications equipment that can detect and record brain activity by brain-computer interaction technology and brain signals. Brain waves are turned into a language that the computer can understand, so as to effectively control the vehicle, or other external devices.
