Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, right below in conjunction with drawings and examples
The present invention is described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention,
It is not intended to restrict the invention.
First embodiment, evaluation method embodiment, details are as follows:
Strike object acts on elastic device, and making elastic device, deformation occurs, and then power does work power in the process if it exists.
The deformation of elastic device is bigger, and the elastic force of generation is bigger, and strike object is finally made to reach maximum displacement, and elastic device generates maximum
Deformation, the first kinetic energy and power acting that hit object are all converted to the elastic potential energy of elastic device.The largest deformation is to beat
Effect is hit, the elastic force that corresponding elastic device generates is practical hitting power size.
However be unscientific to evaluate with practical hitting power because between the different elastic devices with different elastic force with
When deformation relationship, by identical power and the strike (identical strike) with identical just kinetic energy, the deformation quantity of generation are different；I.e.
Make to be elastic force having the same and deformation relationship, by identical power but there is the strikes (different strikes) of different just kinetic energy,
The deformation quantity of generation is also different.Although just having with practical hitting power to evaluate in this way, power is identical but power acting is inconsistent
Different meanings.Then, the elastic force that evaluation should be generated first with generating the elastic device of identical deformation quantity is evaluated.
Have again, when the elastic force of elastic device and deformation have non-linear relation, due to the uncertainty of non-linear relation,
Even if generating identical deformation quantity in the relationship of different characteristic, elastic force is also not uniquely, and evaluation is also without comparativity in this way.
So the elastic force that evaluation should more be generated with generating the standard elastic device of identical deformation quantity is evaluated, and it is known as
Standard evaluates hitting power.Standard evaluation hitting power is defined as follows: standard elastic device being made to generate the evaluation deformation of deformation quantity standard
Hitting power when amount, size are equal to the elastic force that standard elastic device generates.The standard elastic device refers to the elastic force of generation
There is the elastic device of linear relationship with deformation, and elastic device can restore to the original state after removing external force.The standard evaluates shape
Variable is the benchmark being compared between different strikes, i.e., only in the case where same standard evaluates deformation quantity, different strikes just may be used
Than.Drafting standard evaluates hitting power and standard evaluates deformation quantity relation curve, as standard evaluation strike force curve.
Be analyzed from principle and provided specifically using formula below, and respectively to elastic device be standard elastic device and
Non-standard elastic device is illustrated.
When elastic device is standard elastic device, the stiffness factor for being marked with quasi- elastic device is, deformation after catching a packet
Amount is, then have:
(1) formula
--- the practical hitting power that elastic device is measured；
Mechanical power loss during ignoring in elastic system has using the law of conservation of mechanical energy:
(2) formula
--- the first kinetic energy that strike object has during strike；
--- the power that strike object is subject to during strike, is here definite value；
Following relational expression is obtained in conjunction with (1) formula and (2) formula:
(3) formula
To the same strike,WithIt is determining value, is two basic aspects for evaluating striking capabilities.Then real
Border hitting power is determined by deformation quantity, with different stiffness factors elastic device by the same strike when deformation quantity not
Together, the bigger deformation quantity of stiffness factor is smaller, and hitting power is bigger.
Then, strike is uniformly converted into hitting power when standard elastic device being made to generate identical deformation quantity, phase can be made
Same strike and different strikes has unified standard of comparison, and evaluation is just comparable.
The data that measurement can be facilitated in actual measurement and application are practical hitting powerAnd power(power can
With measured in advance, can also be determined during strike), corresponding reality can be acquired with deformation relationship by the elastic force of elastic device
Deformation quantity.Bidding standard evaluates hitting power, standard evaluation deformation quantity be, then the first kinetic energy of object is hitAnd powerDeformation quantity is evaluated in standardThe energy that lower acting generates, the elastic potential energy for being converted into standard elastic device have following relationship:
(4) formula
In conjunction with (3) formula and (4) formula, the relational expression of standard evaluation hitting power and standard evaluation deformation quantity is obtained are as follows:
(5) formula.
When elastic device is non-standard elastic device, the non-standard elastic device refers to the elastic force generated by deformation
There is the device of non-linear relation with deformation, elastic device can restore to the original state after removing external force.It needs to know elastic dress at this time
The specific functional relation of the elastic force and deformation set, this relationship can be obtained by experiment.
If the elastic force and deformation relationship of non-yielding devices are, above (3) formula can be write as:
(6) formula
The expression of standard evaluation hitting power is obtained in conjunction with (4) formula and (5) formula are as follows:
(7) formula
If power is non-constant force, and has functional relation with deformation during strike, then (7) formula turns
It is changed to:
(8) formula
Above-mentioned (4) formula is the basic relational expression that standard evaluates that hitting power and standard evaluate deformation quantity, (5) formula, (7) formula and
(8) formula evaluates the practical application relational expression of hitting power for standard, especially using (8) formula as general expression.
