课程介绍
     The study of the structure and motion of mechanisms in machinery, as well as the structure, force, mass and motion of machines. The main components of this subject are mechanism and mechanical dynamics. Mechanism and machine are generally referred to as machinery. The mechanism is a combination of two or more components connected by activities to realize specified movement. A machine is made up of one or more mechanisms, which are used to do useful work or complete the conversion between mechanical energy and other forms of energy. The research object of mechanism is all kinds of common mechanisms in the machine, such as linkage mechanism, cam mechanism, gear mechanism, screw mechanism, intermittent motion mechanism (such as ratchet mechanism, grooved wheel mechanism, etc.) and combination mechanism. Its research content is the composition principle and motion certainty of mechanism structure, as well as the motion analysis and synthesis of mechanism. Mechanism studies the motion of mechanism only from the point of view of geometry, without considering the influence of force on the motion. The research object of mechanical dynamics is machine or combination of machines. The research content is to determine the real motion law and its regulation, friction and mechanical efficiency, inertia force balance and other issues of the machine under the action of known force.

    机械原理研究机械中机构的结构和运动,以及机器的结构、受力、质量和运动的学科。这一学科的主要组成部分为机构学和机械动力学。人们一般把机构和机器合称为机械。机构是由两个以上的构件通过活动联接以实现规定运动的组合体。机器是由一个或一个以上的机构组成,用来作有用的功或完成机械能与其他形式的能量之间的转换。机构学的研究对象是机器中的各种常用机构,如连杆机构、凸轮机构、齿轮机构、螺旋机构和间歇运动机构(如棘轮机构、槽轮机构等)以及组合机构等。它的研究内容是机构结构的组成原理和运动确定性,以及机构的运动分析和综合。机构学在研究机构的运动时仅从几何的观点出发,而不考虑力对运动的影响。机械动力学的研究对象是机器或机器的组合。研究内容是确定机器在已知力作用下的真实运动规律及其调节、摩擦力和机械效率、惯性力的平衡等问题。

教学方法

    (1)应用多媒体与板书相结合的教学方法。充分发挥学校数字化教室的硬件优势。多媒体软件和资源对于提出问题,揭示矛盾,从工程背景引出理论问题,培养学生发现问题的能力具有很好的效果。并对于扩大课堂信息量,增进工程实践意识,开展师生交互式教学,加强学生对重点、难点的理解和记忆,具有明显的效果。同时,也要利用板书解决讲授中的重点、难点,遵循由浅入深、由简单到复杂、由易到难的教学规律,使学生易于理解所学知识。

    (2)在教学中注意在简捷的数学推导过程中突出思路、突出方法。因此,在数学推导前,首先要有定性分析,使学生懂得“问题是什么?”、“问题的性质是什么?”、“解决问题的方法是什么?”特别注意启发式教学,少一些理论与推导,多一些问题的分析与讨论。

    (3)大学教育应该是“授人以渔” 不是“授人以鱼”。因而在教学过程中关键是要教会学生学习的方法,使得终身受益。要为学生留出充分的思维空间,留出一些问题让学生去想、去自学、去研究;要改变教师“一言堂”,展开课堂讨论,活跃学术气氛。在选课后习题时,要精而少,避免学生"照猫画虎",让学生自己去思考学过的知识,并把知识应用到解题中。

    通过该课程的先进教学方法和教学手段,使学生在较短课时掌握较多知识。学生从对本专业的茫然到了解,最后热爱专业,学生不仅要知道机械原理的内容、思维方式和解决问题的方法,而且要激发他们对机制专业的探索和开拓激情,以及对科学执着的追求精神。


    本课程是一门技术基础课,其最显著的特点是基础理论与工程实际的结合。要用到物理、数学、力学、机械制图和工程材料及机械制造基础等先修课程的知识,尤其是理论力学的知识。但并不是这些课程的简单重复,而是要引导学生如何应用所学的只是解决工程实际中所遇到的问题。所以本课程的学习不同于理论课程的学习,也不同于专业课,而具有一定的理论系统性及逻辑性和较强的工程实践性的特点。因此,在学习本课程时应注意掌握基本的概念、原理及机构的分析与综合的方法。

    注重理论联系实际:本课程并不是研究某种具体的机械,而是着重研究一般机械的共性问题,即机构的结构分析和综合的基本理论和基本的方法。这些基本理论和方法是紧密为工程服务的。因此,在本课程的学习过程中,一方面要注意这些理论和方法在理论上建立和推演的严密性和逻辑性,另一方面更要注意这些理论和方法如何在工程实际中的应用。此外还应随时留意日常生活和生产中遇到的各种机械,以丰富自己的感性认识;并用所学到的理论和方法认识分析这些机械,以加深理解,使理论和实践相互促进。

    初步建立工程观点:本课程要用到很多与工程有关的名词、符合、公式、标准及参数和对机械研究的一些常用的简化方法,如倒置、反转、转化、当量、等效、代换等等。在机构分析与综合中,除解析法外还介、实验法以及试凑等一些工程中实用的方法。因此在学习时,对名词应正确理解其含义,对公式应着重于应用,而对方法则着重掌握其基本原理和作法。另外,实际工程工程问题都是涉及多方面的因素的问题,其求解可采用多种方法,其解一般也不是唯一的。这就要求设计者具有分析、判断、决策的能力,要养成综合分析、全面考虑问题的习惯和科学严谨、一丝不苟的工作作风。

   认真对待教学的每一个环节: 本课程全部教学工作的完成,需要自学、听课、习题课、实验课、课后作业、答疑和考试等教学环节。要学好这门课,希望大家对每个教学环节予以充分重视。


    (1) Apply the teaching method of combining multimedia with blackboard writing. Give full play to the hardware advantages of school digital classroom. Multimedia software and resources have a good effect on raising questions, revealing contradictions, drawing theoretical problems from engineering background, and cultivating students' ability to find problems. It has obvious effect on expanding the amount of classroom information, enhancing the awareness of engineering practice, developing the interactive teaching between teachers and students, and strengthening the students' understanding and memory of key and difficult points. At the same time, we should also use blackboard writing to solve the key points and difficulties in teaching, and follow the teaching law from simple to deep, from simple to complex, from easy to difficult, so that students can easily understand what they have learned.


    (2) In the teaching, we should pay attention to the thinking and method in the simple mathematical derivation process. Therefore, before mathematical derivation, we should first have qualitative analysis to make students understand "what is the problem?" "What is the nature of the problem?" "What is the way to solve the problem?" Pay special attention to heuristic teaching, less theory and deduction, more analysis and discussion of some problems.


    (3) University education should be "teach people to fish" rather than "teach people to fish". Therefore, in the teaching process, the key is to teach students how to learn, so that they can benefit for life. It is necessary to set aside enough thinking space for students and some questions for students to think, study and Study on their own; it is necessary to change the teacher's "one word, open class discussion and activate the academic atmosphere. When choosing exercises after class, students should be precise and less, avoid "drawing pictures from the cat", let students think about the knowledge they have learned, and apply the knowledge to solving problems.


    Through the advanced teaching methods and means of the course, students can master more knowledge in a short period of time. From being at a loss to understanding the major, students love the major at last. Students should not only know the content of mechanical principle, thinking mode and problem-solving method, but also stimulate their passion for exploration and development of mechanism major, as well as the pursuit spirit of scientific persistence.

   

    This course is a basic course of technology. Its most remarkable feature is the combination of basic theory and engineering practice. We should use the knowledge of physics, mathematics, mechanics, mechanical drawing, engineering materials and mechanical manufacturing foundation, especially the knowledge of theoretical mechanics. But it is not the simple repetition of these courses, but to guide students how to apply what they have learned is only to solve the problems encountered in engineering practice. Therefore, the study of this course is different from the study of theoretical courses and professional courses, and has certain characteristics of theoretical system, logic and strong engineering practice. Therefore, we should pay attention to grasp the basic concepts, principles and the methods of analysis and synthesis of the mechanism.

    Focus on the combination of theory and practice: This course is not to study a specific machine, but to focus on the common problems of general machinery, that is, the basic theory and basic methods of structural analysis and synthesis of mechanisms. These basic theories and methods are closely for engineering service. Therefore, in the learning process of this course, on the one hand, we should pay attention to the rigor and logicality of the theoretical establishment and deduction of these theories and methods, on the other hand, we should pay more attention to the application of these theories and methods in engineering practice. In addition, we should pay attention to all kinds of machines in our daily life and production at any time to enrich our perceptual knowledge, and use the learned theories and methods to analyze these machines, so as to deepen our understanding and promote the theory and practice.

    Preliminary establishment of engineering viewpoint: This course uses many engineering related terms, conformity, formulas, standards and parameters, and some commonly used simplification methods for mechanical research, such as inversion, inversion, transformation, equivalence, substitution, etc. In the analysis and synthesis of mechanism, in addition to analytical method, there are also some practical methods in engineering, such as experimental method and trial and error method. Therefore, in learning, we should correctly understand the meaning of nouns, focus on the application of formulas, and focus on mastering the basic principles and practices of the other party's rules. In addition, the practical engineering problems are all related to many factors, which can be solved by many methods, and the solution is not the only one. This requires the designer to have the ability of analysis, judgment and decision-making, develop the habit of comprehensive analysis and comprehensive consideration of problems, and develop a scientific, rigorous and meticulous work style.

    Take every link of teaching seriously: the completion of all teaching work of this course requires self-study, class attendance, exercise class, experiment class, homework after class, question answering and examination and other teaching links. In order to learn this course well, we hope that everyone will pay full attention to each teaching link.
