Abstract: It is well known that the oil-gas-water three-phase flow belongs to the field of multiphase flow,transfer heat mechanism of which is very complicated.Transfer heat mechanism is affected not only by different buries in oil gathering pipeline, but also by soil temperature periodicity change. Both domestic and oversea scholars have already studied on the transfer heat mechanisms of oil-gas-water three phase,but they are still in the level of fundamental theory and laboratory.This paper establishes transfer heat models of the oil-gas-water three-phase flow in buried oil gathering pipeline, including the physical model and the mathematical model,and testing in experiment .The purpose of this paper is to analyze value between the calculation and the testing . The results show that the mathematical model of this paper is accurate , and the relative error is ≤ 10%.

Abstract: Anisotropic materials have been widely applied in practical engineering problems of interest. In the paper, the anisotropic heat transfer behaviors are analyzed using the proposed hybrid finite element model with Green’s function kernel. In the established weak integral hybrid functional, the element internal field being approximated with the combination of Green’s function satisfies a priori the governing partial differential equation and the independent frame field is assumed to link the internal field. As a result, the solving linear system of equations with boundary integrals only is obtained and the constructed elements show anisotropic feature. Two numerical examples are given to show the convergence and accuracy of the proposed approach, and the effect of ply angle of orthotropic material principal direction on the temperature distribution is discussed to investigate heat transfer mechanism in anisotropic materials.

Abstract: How to use simulation software AMESim to build the drive system model of some type of armored assault vehicle is introduced. Accelerating and steering on various kinds of roads and those with different gradients are dynamically simulated. The analysis of the performance parameters changing with time of each gear, driving shaft, hydraulic steering gear, driving wheel and engine will provide theoretic references for improvement of this vehicle.

Abstract: Hydraulic press is important pressure processing equipment, which has a wide range of applications in production and manufacturing industry. The structure of hydraulic press frame has an extremely significant effect on safety and usability. Against the structure of frame-type hydraulic press in this paper, a solid model has been built with CAD program Pro/E and the hydraulic press frame under working conditions is simulated by finite element simulation program ANSYS. This paper analyses the variation of stress, strain and frame deformation under working conditions, and the dangerous sections of hydraulic press frame can be found under the maximum work load. The research results show: The maximum value of effective strain and effective stress can be found in the screw holes of cylinder port, the maximum value of stress and strain in the direction of hydrocylinder force can be found in the confluence of upright column and lower beam, the maximum value of effective displacement and the displacement in the direction of hydrocylinder force can be found in cylinder port and part of upper beam.

Abstract: Engineering practice education is important for engineering college students, but it needs the support of infrastructure and human input. With the number of students expanding dramatically in many local colleges or universities since the 21cn, resources of practice teaching can not meet the requirements of personnel training. With the development of the society and technologies, old practical teaching model also can not adapt to the demand of human resource market. This article presents the status of the current practice teaching and sums up many problems of local colleges and universities. In addition some reform ideas and exploration are presented in Anhui University of Architecture （AUA）

Abstract: Training of basic quality and ability of students is always a primary goal for the higher mechanical engineering education, innovation design practice in machine theory are very important method to train the basic quality and ability, independent of thinking, the spirit of cooperation of students. In the innovation design practice, the subjects generally come from three sources, the students should be grouped freely and every group is not less than three people and not more than five people. At the same time, the basic content of investigation report and feasibility report are introduced, an example of innovation design practice scheduling used for years and some questions which should be paid special attention are also provided.

Abstract: Currently, the education of engineering college faces the pivotal problem of how to improve students' engineering practice ability. Combining the practice teaching system of engineering practice ability cultivation for the major of process equipment and control engineering in our college, four-year continuous persistent cultivation of engineering drawing ability can improve the students' engineering practice ability effectively and practically.

Abstract: Automatic Dynamic Analysis of Mechanical System (ADAMS) provides a powerful modeling and simulating environment that helps people to build, simulate, refine, and ultimately optimize any mechanical system. In the classroom teaching of mechanism course, to use ADAMS to show the establishment and movement of all kinds of mechanisms and their simulation process of kinematics and kinetics as a demonstration will significantly enrich students' perceptual knowledge, enlighten and guide students cogitation, stimulate their interests in mechanism thereby enhance the effectiveness of course teaching.

Abstract: As a specialized base course of mechanical engineering specialty, study of mechanics course plays an important role of bridge to study other specialized courses. Students who learns mechanical course better will be usually quite smoothly in their successor curriculum studies. Not only does it influence the studies of specialized curriculum, course design, graduation design, etc, but also their employment in the future directly. It is the duty of the teachers to improve quality of teaching mechanical courses and enhance students' various abilities. In this paper, introduces how to improve students’ abilities relying on two platforms of the network and competition during the teaching.

Abstract: According to the analysis of the existing problems of graduate education of mechanical engineering in local college, the necessity is explained for the team construction of adjunct graduate tutor. Based on the joint base of Shandong Province for graduate education which is established by the University of Jinan (UJN) and the Jinan Foundry& Metal forming Machinery Research Institute Co., Ltd. (JFMMRI), practice is carried out to establish a team of adjunct graduated tutor and to explore the education mode of graduate student under the co-operation of Industry-Academia- Research (IAR).
