Problems solved by technology

To evaluate or reflect the size of the impact by the impact effect, only the results given by the same measuring device are comparable, and the results given by different measuring devices are not comparable
[0008] However, even if the same measuring device can realize the comparison between different strike effects, it is only a comparison of the size relationship under specific conditions, and does not fundamentally give the evaluation of the striking ability of the striking object, so that different striking effects cannot be realized. Comparisons under different conditions, and the specifics of not being able to give the same blow under different conditions

[0050] The first embodiment, the evaluation method embodiment, is described in detail as follows:

[0051] The striking object acts on the elastic device to deform the elastic device. If there is power, the power will do work in the process. The greater the deformation of the elastic device, the greater the elastic force generated, and finally the strike object reaches the maximum displacement, the elastic device produces the maximum deformation, and the initial kinetic energy and dynamic work of the strike object are all converted into the elastic potential energy of the elastic device. The maximum deformation is the striking effect, and the elastic force generated by the corresponding elastic device is the actual striking force.

[0052]However, it is unscientific to evaluate the actual impact force, because when different elastic devices have different elastic force and deformation relationships, the impacts with the same dynamic force and the same initial kinetic energy (t...

Abstract

The invention discloses a strike capability assessment method and an assessment device. In one embodiment of the invention, the strike capability assessment method comprises the following steps: a striking object acts on an elastic device to ensure the elastic device is deformed; elastic force generated by the elastic device is measured, and a deformation amount is computed; elastic potential energy obtained by the elastic device is computed, and initial kinetic energy suffered by the striking object is computed according to known or assessed power of the striking object; under a standard assessment deformation amount, the initial kinetic energy and the power of the striking object act to generate energy, the energy is converted into standard elastic potential energy of the elastic device, and then standard assessment strike capability corresponding to the standard assessment deformation amount is computed; a relation curve of the standard assessment strike capability and the standard assessment deformation amount is drawn, so that a standard assessment strike capability curve of assessment strike capability is obtained.

Description

technical field [0001] The present invention relates to a method and an evaluation device for evaluating striking ability, specifically, a method and an evaluating device for evaluating striking ability based on a standard evaluation striking force curve. Background technique [0002] The striking ability in the present invention refers to that when an object with a certain speed (hereinafter referred to as the striking object) acts on another object (hereinafter referred to as the striking receptor), the other object is deformed and / or the state of motion is changed. (That is, the striking effect), the ability of the striking object to cause the striking receptor to produce the striking effect is called the striking ability. [0003] The striking ability is the inherent ability of the striking object, and the standard evaluation of the striking force curve can be used as an evaluation item, and the evaluation results should not be different due to different striking recepto...
