This paper focus on marking process simulation and product identification of Plate Marking Machine, which are the two basic process of product life trace. The system construction, working principle and marking process are introduced, and the virtual simulation can run step by step and be saved as bitmap file or stream file. A new Vector arithmetic is introduced in character recognition with standard recognizing library instead of special library which needs a lot of training process. In vector arithmetic new x-y axis are built with least-squares method which estimates the measurable step units. The simulation and character recognition give a better resolution of marking machine for BaoSteel especially in product life trace, which has good actual performance. © 2010 IEEE.

This paper presents a general control iteration algorithm for a class of chaotic systems. The algorithm contains two iterations, which are performance index function iteration and the corresponding control iteration. In order to prove theoretically, two theorems are proposed, which demonstrates the iteration algorithm is convergent. At last, an example is given to show the effectiveness of the proposed algorithm. © 2013 SPIE.

Based on coupling and low damp ratio of the marking process, this paper presents a new approach for modeling system by dividing the whole process into several periodic dynamic processes, in which the new methods decouple the pressure system and position servo system and raise the damp ratio of pressure system and lower the inner-influence of paint guns. A theoretic analyses and digital simulation about the system of marking process are made at different paint pressure and different servo speed using Matlab. The simulate results give a better group of system parameters for marking machine in BaoSteel, which has good actual performance and the methods for improving the marking characteristic are given. © 2010 IEEE.

In this paper, the study object is a vibrating screen driven by two motors. A new analytical method is proposed to study the dynamic feature of the screen. With introduction of two small variable parameters to average angular velocity of two exciters and their phase difference, the parameters of the model were dimensionless processed, and then the synchronization condition and stability condition of the vibrating screen were deduced. Computer simulation results based on synchronization condition and stability condition show that the vibrating screen realizes speed synchronization and phase synchronization, the system is in a good self-synchronous state. © (2012) Trans Tech Publications, Switzerland.

This paper studied the impact of differential settlement of foundation on the inner force of architectural structure by applying back-analysis method. By taking the three-dimensional coactions system of upper structure-piled raft foundation-foundation with different pile length and different raft thickness as the research object, its differential settlement law of foundation under the effect of load was studied, which was combined with the practical measured data to fit the quadratic settlement surface equation of the foundation. The analysis demonstrated that the differential settlement of foundation will change the inner force of upper structure significantly, thus enabling most of construction components to produce great additional axial force, additional shearing force and additional bending moment, especially changing the additional inner force of corner post more evidently. © (2013) Trans Tech Publications, Switzerland.
