The phenomenon occurs in the process of movement and change, and people who are good at thinking will start withWhy, use your brainGet to the bottom of it, launching, why does the water flow under the rotation line?The faster the spinning top turns, the more stable it isBeginners will feel that the faster they pedal, the more stable they arePeople who are good at using their brains will realize that this is a law of nature, that it is rotational motion, and that it produces the axial force that maintains the rotational state, and this force is called itRotational state steady-state maintenance force, orAdhesion
There are conventional mechanical mechanismsClosed-loop self-followRing, there isOpen it loopsBoth. The inspiration of mechanisms such as wire strippers has led to the realization that there is another mechanism:Externally constrained two-degree-of-freedom maneuvering,Not to be ignored. This kind of institution is not in university textbooks, tooIt was supposed to become a modern linkageofImportant part
Transattachment discovery is an extension and upgrade of understandingIt is the achievement of a common theory。This rotational state maintenance force can be applied to any of the different professions and fields, can be used in any state rotation design, can explain and understand why the earth is elliptical: yesThe role of transadhesionCausing the earth's magma to move along the axis of rotation to form an ellipse, this kind of academic thought andThe principle that everything always maintains its own potential energy minimumThe cause of ** can be understood and explained.
Utilizes the principle of adhesion forceusIt is possible to increase the speed and power capabilities of the rocket engineIt can innovate the design of pneumatic conveying process equipment, and can innovate the design of the spraying capacity of the nozzle related to environmental protection dust removal.
Plus a constraint with two degrees of freedomIt is also an indispensable mechanical equipment design and application in heavy machinery, among which the floating shaft parallel blade shear is a typical one, the invention and design of this heavy machinery ** former Soviet Union mechanical expert Chaikova (). This kind of heavy-duty mechanical shears with a power capacity of several hundred tons can neatly cut other red-hot steel such as square steel like a face. How it worksYesTwo degrees of freedom with constraints attachedFunctional structure monetization application.
Some people learn Xi Carikova shearing machine, not to learn Xi design ideas and design mechanisms, but to talk about things and machines. So this is the main reason why we don't have theorists and theorists.
This two-degree-of-freedom mechanism can also realize step-by-step programmable function movement without the need for electrical sensing cooperation. This design idea is not the work of some experts and professors, but the creation of an enterprise engineer who graduated in the 70s of the red era, and the institution was read out at the National Association of Invention and Invention of Invention Machinery Institutions before the reopening.
The achievements of this mechanical mechanism have solved the problem of automatic positioning of the engine body with the cylinder liner hole, a provincial management enterprise in this, before the design of the body positioning and clamping scheme, has found a famous college graduate engineer, technician, and even a chess expert, a smart person, and other capable people to give advice, but there is nothing to be done. Later, I found the authorInnovate with the principle of two degrees of freedom with the addition of the endDesign it out, a cylinder action to achieve 4 different action mechanism, a design and manufacturing experiment successful.
The new theoretical concept that building is not an act of persistence, but an intuition from creativity to the realization of consciousness, from awarenessThe future world needs to apply functions to the monetization of institutions
Classical mechanics has the law of inertia, but those who have academic qualifications, professional titles or even the highest professional titles, some people may not have a good understanding of inertia. Inertia of force + mass = inertia. There is inertia in the attitude and state of the object, and there is inertial maintenance and superposition or differential ,...... in velocityand so on.
Someone is involved as inertia, and human inertia (XiYesIncreasing regularity by formula, there are people who love to drink, the more they drink, and the more they gamble, the more they become inertia, the more ,...... they are blockedThis is the embodiment of deepening understanding. This understanding is very useful for social relations.
Those who learn and know only know things that Xi other people's books, and even learn foreign languages and learn things Xi foreign countriesHe doesn't know that phenomena and processes of change are your wordless booksThe things that can be learned are those who already have something and those who don'tYou can never learn something. Those who only rely on learning and knowing cannot make regular discoveries, and they are the leaders and pioneers of product invention。Some math teachers only know that natural numbers are: 1, 2, 3, ......, I don't knowThere is only 1 after that2.3，……, I don't knowThe status of none is 0Expression。So the correct nature is: 0, 1, 2, 3 ,......
The correct understanding of natural numbers is of great significance；The author found the inventionInstitutional degrees of freedom are inferred from the remainder ruleMedium,The number of natural numbers starts from 0, and then the slider mechanism, the rotation mechanism....Simple Mechanism Positioning Mechanism First Institution Map。Otherwise, some scholars and experts only think that the 4-pole mechanism is the first type of the institution. The relevant formulas of other industry majors may also be related to the orientation of natural numbers.
The opening and closing nut mechanism is an innovative design in mechanism, the integral nut is designed to be composed of an opening and closing half nut, which can transform the screw mechanism into a guide rod mechanism, which is a variation and mutual transformation mechanism of the screw - guide rod, which gives an increase in the speed of the mechanism in some mechanisms, such as the ...... of the invention project of the fast jack. Because the project involving the nut mechanism is applying for a patent, the author cannot give a graphical explanation.
The formulation and establishment of a certain formula also plays an important role in the design. The length and width of the effective guide and the coefficient of friction of the effective pair of the shifterThere is a certain correlation between quantity and value. It is a useful formula for the reliability of mechanical design. The author of this article has been elaborated in an article in Baijiahao.
Some hydraulic systems or hydraulic presses, especially four-column presses, are designed by the user to guide the part in order to save materialslandUnreasonableness is the main reason for Caton crawling. Some people also mistakenly think that it is hydraulic crawling, which is a matter of theory and theoretical thinking.
Guided does not operate according to the theoretical concept, but is inclined within the allowable range of its gapsThe design is unreasonable, which also has this problem in foreign-funded enterprises or design, so it is necessary and necessary for scientific and technological workers to realize this mechanism or design formula.
Theory is a guide for practitioners!A powerful tool for innovation is theoretical thinking
