The centrifugal force experiment has the technical effects that:
the centrifugal motion refers to a phenomenon that an object moves away from a center, a centrifugal machine of an American uranium enrichment factory extracts a nuclear raw material by utilizing the centrifugal motion, when the object does non-linear motion (non-Newtonian environment, such as circular motion or turning motion), because the object has certain mass, the inertia caused by the mass can force the object to continuously move towards the tangential direction of a motion track (the original straight direction advancing at the moment) instead of the direction going along the turning path.
If there is a passenger on an object (e.g. a vehicle) which does not move linearly, the passenger will be subjected to a centripetal force provided by the vehicle to the passenger due to the turning motion of the vehicle, but if the passenger is taken as a reference system, the passenger will be subjected to a centripetal force directed to the center of the circle by the vehicle which is relatively stationary, but will be given a force of equal magnitude in opposite directions by the vehicle due to the non-inertial system, and the force is a so-called centrifugal force as if the passenger were to be thrown away without the vehicle.
The centrifugal force of the object in the non-inertial system rotating relatively is F ═ m ω ^2r (wherein ω represents the angular velocity of rotation of the non-inertial system itself.
From this the formula F ═ m ω ^2r (where ω denotes the angular velocity at which the non-inertial system itself rotates is calculated from the centrifugal force.
The skilled worker performed a centrifugal force impact test, and the obtained test data were as follows:
according to the above table, it can be seen that, under the condition that the mass of the centrifugal impact rod 42 is constant, the swing spring 41 therein defines the rotation radius of the centrifugal impact rod 42, so that the greater the angular velocity of the rotation of the centrifugal impact rod 42, the greater the centrifugal force applied thereto, and when a greater centrifugal force acts on the aluminum pipe 2 and the copper pipe 21, because the aluminum pipe 2 and the copper pipe 21 are fixed, a part of the centrifugal force will be offset under the limiting action of the aluminum pipe 2 and the copper pipe 21, and a greater centrifugal force will reach a force-removing effect towards both sides, so that the centrifugal impact rod 42 will move towards both sides under the limiting action of the aluminum pipe 2 and the copper pipe 21, and under the action, the copper ions adsorbed on the outer surface of the aluminum pipe can be uniformly adsorbed on the surface of the aluminum pipe, and at the same time, the impurities precipitated on the outer surface of the copper pipe can be removed.
An aluminum pipe with copper plated on the surface is produced by the following process;
s1, enabling a worker to enable a copper plating solution to enter the copper plating box 1 through the solution inlet hopper 12, enabling the aluminum pipe 2 and the copper pipe 21 to be placed inside the copper plating box 1 in a rotating mode, starting the motor 31, enabling the rotating rod 3 to be driven to rotate by starting the motor 31, enabling the arc-shaped friction stirring blades 4 to rotate by rotation of the rotating rod 3, enabling the device to stir the copper plating solution when the arc-shaped friction stirring blades 4 rotate, enabling the copper plating solution to rapidly react with the copper pipe 21, further improving copper plating efficiency of the device, enabling the aluminum pipe 2 and the copper pipe 21 to rotate under the pushing of lateral friction force when the arc-shaped friction stirring blades 4 rotate to rub the aluminum pipe 2 and the copper pipe 21, enabling the aluminum pipe 2 and the copper pipe 21 to uniformly react with the copper plating solution, and enhancing copper plating effect of the device.
S2, under the rotation effect of the arc friction stirring blade 4, the swing spring 41 utilizes the centrifugal force generated by the rotation of the swing spring to enable the centrifugal impact rod 42 to collide with the outer surfaces of the aluminum pipe 2 and the copper pipe 21, and due to the swing irregularity of the swing spring 41, the centrifugal impact rod 42 is laterally deviated when colliding with the aluminum pipe 2 and the copper pipe 21, so that copper ions adsorbed on the outer surface of the aluminum pipe 2 can be uniformly adsorbed on the surface of the aluminum pipe 2, and impurities precipitated on the outer surface of the copper pipe 21 can be cleaned, thereby enhancing the reaction effect of the device.
S3, when the centrifugal impact rod 42 impacts the aluminum pipe 2 and the copper pipe 21, the T-shaped reinforcing rod 6 can be relatively displaced under the action of the arc elastic rod 61 under the action of the extrusion force, so that the aluminum pipe 2 and the copper pipe 21 can rotate and have a lateral moving thrust, the cleaning of the outer surfaces of the aluminum pipe 2 and the copper pipe 21 is facilitated, and the copper plating effect of the device is enhanced.
S4, when the arc friction stirring blade 4 rotates to collide with the auxiliary arc elastic rod 71, the auxiliary arc elastic rod 71 is deformed under the action of the impact force, so that the swinging straight rod 8 swings towards two sides, the extrusion plate 9 can push the copper plating solution to gather towards two sides of the aluminum pipe 2 and the copper pipe 21 under the action of the swinging straight rod 8 under the swinging effect, and further copper ions in the copper plating solution can gather near the aluminum pipe 2 and the copper pipe 21, so that the reaction rate of the device is accelerated, and the copper plating effect of the device is enhanced.

s2, under the rotation effect of the arc friction stirring blade (4), the swinging spring (41) utilizes the centrifugal force generated during the rotation to enable the centrifugal impact rod (42) to collide with the outer surfaces of the aluminum pipe (2) and the copper pipe (21), and due to the swinging irregularity of the swinging spring (41), the centrifugal impact rod (42) laterally deflects when colliding with the aluminum pipe (2) and the copper pipe (21), so that copper ions adsorbed on the outer surface of the aluminum pipe (2) are uniformly adsorbed on the surface of the aluminum pipe (2), and impurities precipitated on the outer surface of the copper pipe (21) are cleaned at the same time, thereby enhancing the reaction effect of the device;
s3, when the centrifugal impact rod (42) impacts the aluminum pipe (2) and the copper pipe (21), the T-shaped reinforcing rod (6) is enabled to relatively displace under the action of the arc-shaped elastic rod (61) under the action of the extrusion force, so that the aluminum pipe (2) and the copper pipe (21) have a lateral moving thrust while rotating, the cleaning of the outer surfaces of the aluminum pipe (2) and the copper pipe (21) is facilitated, and the copper plating effect of the device is enhanced;
s4, when the arc friction stirring blade (4) rotates to collide with the auxiliary arc elastic rod (71), the auxiliary arc elastic rod (71) is deformed under the action of the impact force, so that the swinging straight rod (8) swings towards two sides, and the extrusion plate (9) pushes the copper plating solution to gather towards two sides of the aluminum pipe (2) and the copper pipe (21) under the action of the swinging straight rod (8) under the swinging effect, so that copper ions in the copper plating solution gather near the aluminum pipe (2) and the copper pipe (21), thereby accelerating the reaction rate of the device and enhancing the copper plating effect of the device.
