The mine logistics transportation system with belt and surge links is often formed by a complex hybrid dynamic system that consists of continuous and discrete links, and these parts can have the complex changes along with the mining engineering going on. Studying the hybrid system with belt and surge links to fully realize its beneficial functions is very significant. Until now, there have been many references studying the logistics transportation hybrid system with belt and surge links, and many concepts about it have been set up. However, in these references, complicated real-time dynamic changes of the hybrid system usually is studied. This paper presents a novel approach to study real-time dynamic optimization analysis and simulation problems of complex mine logistics transportation hybrid system, which can be used to make optimization design for this kind of complex hybrid system. The proposed method considered expressly complicated real-time dynamic changing of the hybrid system comparing with some existing references and can solve some optimization design problems of the hybrid system. In addition, this paper used statistical data of a real logistics transportation system with belt and surge bin on simulation and gets some useful conclusions. The application result shows that the presented method is valid.

In order to process heterotype hole of workpiece precisely, an open abrasive flow polish machine is designed, and the optimization design of machine frame is done for low cost. Firstly, basing on the parameters designed with traditional ways, three-dimensional force model is set up with the soft of SolidWorks. Secondly, the statics and modal analysis for machine body have been done in Finite element methods (FEM), and then the optimization analysis of machine frame has been done. At last, the model of rebuild machine frame has been built. Result shows that the deformation angle value of machine frame increased from 0.72′ to 1.001′, the natural frequency of the machine decreased from 75.549 Hz to 62.262 Hz, the weight of machine decreased by 74.178 Kg after optimization. It meets the strength, stiffness and angel stiffness requirement of machine, reduces the weight and cost of machine.

The dynamic performance of PingQiao of abnormal high tower crane is particularly important to the whole structure. Using the finite element method to set up the finite element parametric model of PingQiao of the abnormal high tower crane, and then making dynamic analysis. Taking the analysis result as the objective function of the optimization design model,and using the optimization algorithm module of ANSYS to make dynamic optimization design of PingQiao structure,the quality of PingQiao of the abnormal high tower crane is effectively reduced, the dynamic performance of the metal structure is improved,this lays the foundation for the whole optimization.

The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can be run and analyzed in ABAQUS. The MATLAB language is used to compile the optimization analysis program based on genetic algorithm, and then the dynamic calculation model is embedded into it. Using excavation area, plastic zone, ground surface settlement, vault subsidence, etc. as optimal objective to make dynamic analysis for the model and put forward the reasonable flat ratio of the supported project. The result of this paper provides reference for the section optimization design of similar tunnel engineering.
