2 results about "Elastic energy" patented technology

Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner. Elasticity theory primarily develops formalisms for the mechanics of solid bodies and materials. (Note however, the work done by a stretched rubber band is not an example of elastic energy.

Device and method for measuring heat exchange coefficient of interface in hot stamp process

ActiveCN103033530ARealize the test of interface heat transfer coefficientAvoid incomingMaterial heat developmentSheet steelMeasurement device
The invention discloses a device for measuring a heat exchange coefficient of an interface between a high-temperature steel plate and a die in a hot stamp process. The device comprises a pressure applying device and a measurement device, wherein the pressure applying device comprises a pressurization device, an upper workbench and a lower workbench, wherein the pressurization device is connected with the upper workbench and the lower workbench respectively; the measurement device comprises an upper fixture, a lower fixture and a test sample fixing fixture; the upper fixture is fixed on the upper workbench; the lower fixture is fixed on the lower workbench; and the test sample fixing fixture is arranged between the upper fixture and the lower fixture. The invention also discloses a method for measuring the heat exchange coefficient of the interface between the high-temperature steel plate and the die in the hot stamp process. By the device and the method, the limitation to samples with the thickness being more than 30mm in the prior art is avoided; the heat exchange coefficient of the interface between the steel plate and the die in the hot stamp process can be measured; and by an elastic energy storage element, stabilization of interface pressures between a boron steel test sample and an upper die and between the boron steel test sample and a lower die can be guaranteed.

Ultra-light amorphous reinforced carbon fiber table tennis bat and preparation method thereof

ActiveCN111420375ASolve poor ball control performanceSolve the weakness of poor hand feelingSynthetic resin layered productsLaminationFiberCarbon fibers
The invention discloses an ultra-light amorphous reinforced carbon fiber table tennis bat. The table tennis bat comprises a core plate, a carbon fiber layer and an amorphous alloy layer, wherein the core plate is mainly made of a foaming material; wherein the carbon fiber layer is coated outside the core plate; and the amorphous alloy layer is coated outside the carbon fiber layer. The surface ofthe table tennis bat is provided with a plurality of layers of amorphous alloy thin strips, the table tennis bat has the advantages of being high in elastic energy storage and moderate in modulus, thebat bottom plate can rapidly generate corresponding deformation during low impact, ball control is facilitated, and the defects that the ball control performance is poor and the hand feeling is poordue to the fact that the rigidity of a carbon fiber table tennis bat is too large are thoroughly overcome; and when the table tennis ball is subjected to large impact, the amorphous alloy has high-elasticity stored energy, so that the strength can be more effectively transmitted to the table tennis ball through a rubber sheet, the ball hitting efficiency is improved by over 30 percent, and the table tennis ball is particularly suitable for attacking methods such as loop balls and the like.
