Force values and hardness measurement terms and definitions
This specification is commonly used terms and definitions of force value and hardness, including general terms of force value and hardness measurement,
Management methods, measurement standards and measuring instruments and so on.
A force value
1 force base (standard) quasi machine
1.1 force force
Interactions between objects.
1.2 million gravitation universalgravitation
The mutual attraction between any two objects. The direction of the force along the two objects in the connection direction, size and
The mass of the two objects is proportional to the product and inversely proportional to the square of the distance between the two objects.
1.3 Gravity gravity
The Earth's attraction to an object and the force of this object with the centrifugal force caused by the Earth's rotation.
1.4 elastic force elastica
Two objects in direct contact with the elastic deformation occurs, the deformed objects trying to restore the original shape and size, between each other
Produced by the force.
1.5 gravity acceleration gravityacceleration
Acceleration caused by gravity near the surface of the earth.
1.6 Newton Newton
China's legal units of measurement units. The symbol is N, which is given in SI basic units
Kg · m · s-2.
1N is a force that causes a mass of 1 kg to produce an acceleration of 1 m/s2 in the direction of force.
Note. 1kgf = 9.80665N
1tf = 9806.65N
1dyn = 10-5N
1.7 force standard machine forcestandardmachine
Produce a standard force value for the verification, calibration dynamometer (or load cell), in line with national measurement technology
Regulatory machinery.
Note. The force standard machine usually has four types. static heavy type, lever type, hydraulic type and superposition type.
1.8 force reference machine primaryforcestandardmachine
The administrative department of measurement under the State Council is responsible for establishing, as a unit of recurrence and preservation of value, the highest national unity
Based on the force standard machine.
1.9 deadweight force standard machine deadweightforcestandardmachine-DWM
Take the gravity of the weight as a standard load, automatically and steadily load the load directly by the appropriate mechanism in a predetermined order
Force applied to the seized, school dynamometer (or load cell) on the standard machine.
