Problems solved by technology

[0020] ①It does not involve the unified relationship between the change and its controlling factors, and is not applicable to the field of mechanical equilibrium research
[0021] ② Strong one-sidedness, does not involve the balanced operation process and unbalanced operation process and the unified relationship between the two operation processes
[0022] ③The functional concept and quantitative method of mechanics have artificial prescriptiveness, and have the defect of deviating from the law of objective and unified relationship between energy and action, thus greatly weakening the scientific nature of functional balance theory
[0024] ⑤ Energy balance theory does not involve the relationship between balance and imbalance and its controlling factors, cannot measure the degree of balance and imbalance, cannot describe the process of balance and imbalance, and is not suitable for the study of mechanical balance or functional balance and imbalance
[0025] In previous researches on action science, the relationship between action and change was mainly involved, and the law of the relationship between balance and instability phenomena and motion was not involved.

Embodiment 1

[0053] Such as figure 1 As shown, an object with mass m is placed on an inclined plane with inclination angle α, please analyze the stability of the object on the inclined plane. Suppose the frictional resistance is R.

[0054] Solution: if figure 1 As shown, the force and amount of action to control the movement of the object are produced by gravity, and the two are respectively

[0055] F=G=mg and A=Ft=mgt.

[0056] In the formula, A and F respectively represent the action amount and force that drive the object to move; G represents the gravity on the object; g represents the acceleration of gravity; t represents the time for the object to accept the action. The force and amount of action that control whether the object runs always exist. A and F are the dominant factors that control whether the object is unstable or not, that is, whether it slides. However, whether the object is stable or unstable depends on the nature of the sliding surface. control. The sliding surfa...

Embodiment 2

[0087] Such as figure 2 As shown, the supporting force N of the lever at the fulcrum O, the gravity G at the point P 1 = mg and the gravity G at point Q 2 =Rotate under the joint action of Mg, OP=b, OQ=c, please analyze the equilibrium stability of point P, calculate the characteristic value of its equilibrium stability property, and give its instability condition.

[0088] Analysis: The overall three points of the lever PQ are acted on, and the acting points are respectively located at three points O, P, and Q, and the acting forces are respectively N and G 1 , G 2 , the lever does not deform under the action of these three forces, so the lever can be regarded as a rigid body. If the lever deforms, it is either a non-rigid or deformable body. The following analysis is based on the functional theory as follows:

[0089] (1) Overall effect analysis:

[0090] a. Cooperative analysis in the direction of the fulcrum force F:

[0091] Such as figure 2 As shown, the overal...

Abstract

The invention relates to an action science method for a balance and unbalance phenomenon. The method comprises a balance and unbalance research theory method and a balance and unbalance research function method, wherein the balance and unbalance research theory method is a method for directly calculating balance and unbalance parameters or determining balance and unbalance functions according to an action science basic theory formula; and the balance and unbalance research function method is characterized in that, according to the action science basic theory, the equation of motion of a pointunder action is determined, and then, the balance and unbalance functions or balance and unbalance parameters contained in the equation of motion are found in the equation of motion. The method has the beneficial effects that an action science new theory determines a balance and instability theory and method which is more scientific than traditional mechanics, a current situation that only the balance and unbalance phenomenon can be described but a balance stability degree and an instability degree can not be measured in the past can be changed, a new-period scientific and technological revolution is brought to the human being, and an effective scientific theory basis is provided for engineering construction, scientific prediction and disaster prevention and control.

Description

technical field [0001] The invention relates to an functional method for studying balance and imbalance phenomena, which belongs to the technical field of functional balance. Background technique [0002] Among the current basic scientific theories at home and abroad, the theory that studies the phenomenon of balance and imbalance is called balance theory. Based on the differences in theoretical characteristics, research fields, research methods, and application scope, current balance theories at home and abroad can be divided into three types: basic mechanical balance theory, analytical mechanical balance theory, and energy science balance theory. [0003] 1. The basic mechanical balance theory mainly includes force balance theory and torque balance theory. The core content of force balance theory consists of force balance equations. which is [0004] ΣF i =0. [0005] The core content of the moment balance theory is constituted by the moment balance equation. which i...
