Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is 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 limit the invention.
First embodiment, evaluation method embodiment, details are as follows:
Strike thing acts on elastic device, deforms upon elastic device, power does work in the process if it there is power.Elasticity
The deformation of device is bigger, and the elastic force of generation is bigger, strike thing is reached maximum displacement, and elastic device produces maximum shape
Become, the first kinetic energy and power acting that hit thing are all converted to the elastic potential energy of elastic device.The largest deformation is strike
Effect, the elastic force that corresponding elastic device is produced is actual hitting power size.
But it is unscientific to be evaluated with actual hitting power because when between different elastic devices have different elastic force with
During deformation relationship, hit by identical power and with identical just kinetic energy(Identical is hit), the deformation quantity difference of generation;I.e.
Make to be, with identical elastic force and deformation relationship, to be hit by identical power but with different just kinetic energy(Different strikes),
The deformation quantity of generation is also different.So, although power is identical but power acting is inconsistent, just has to evaluate with actual hitting power
Different meanings.Then, the elastic force that evaluating should be produced with producing the elastic device of identical deformation quantity first is evaluated.
Have again, when the elastic force of elastic device has non-linear relation with deformation, due to the uncertainty of non-linear relation,
Even if producing identical deformation quantity, elastic force in the relation of different characteristic nor unique, so evaluation is also without comparativity.
So, the elastic force that evaluating should more be produced with producing the standard elastic device of identical deformation quantity is evaluated, and is referred to as
Standard evaluates hitting power.Standard is evaluated hitting power and is defined as follows:It is that standard evaluates deformation standard elastic device is produced deformation quantity
Hitting power during amount, its size is equal to the elastic force that standard elastic device is produced.The standard elastic device refers to the elastic force produced
Having the elastic device of linear relationship with deformation, and remove elastic device after external force to restore to the original state.The standard evaluates shape
Variable is the benchmark being compared between different strikes, i.e., only evaluated in same standard under deformation quantity, different strikes just may be used
Than.Drafting standard evaluates hitting power and evaluates deformation quantity relation curve, as standard evaluation strike force curve with standard.
Analyzed below from principle and provide it is specific apply formula, and be to elastic device respectively 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
Measure and be, then have:
(1)Formula
--- the actual hitting power that elastic device is measured;
Mechanical power loss during ignoring in elastic system, using the law of conservation of mechanical energy, has:
(2)Formula
--- the first kinetic energy that strike thing has during strike;
--- the power that strike thing is subject to during strike, is here definite value;
With reference to(1)Formula and(2)Formula obtains following relational expression:
(3)Formula
To same strike,WithIt is the value of determination, is two basic aspects for evaluating striking capabilities.Then it is actual to beat
Power is hit by deformation quantity to determine, the elastic device with different stiffness factors is different by deformation quantity during same strike,
Stiffness factor gets over that large deformation amount is smaller, and hitting power is bigger.
Then, strike is uniformly converted to hitting power when making the standard elastic device identical deformation quantity of generation, with regard to phase can be made
Same strike and different strikes has unified standard of comparison, and evaluating just has comparativity.
The data that can be conveniently determined in actually measurement and application are actual hitting powerAnd power(Power can be with
Measured in advance, can also be determined during strike), corresponding actual shape can be tried to achieve by elastic force and the deformation relationship of elastic device
Variable.Bidding standard evaluates hitting power, standard evaluate deformation quantity be, then the first kinetic energy of thing is hitAnd power
Deformation quantity is evaluated in standardThe energy that lower acting is produced, being converted into the elastic potential energy of standard elastic device has following relation:
(4)Formula
With reference to(3)Formula and(4)Formula, the standard that obtains evaluates hitting power and the relational expression of standard evaluation deformation quantity is:
(5)Formula.
When elastic device is non-standard elastic device, the non-standard elastic device refers to the elastic force produced by deformation
There is the device of non-linear relation with deformation, removing elastic device after external force can restore to the original state.Now need to know elastic dress
The elastic force and the specific functional relation of deformation put, this relation can be drawn by experiment.
If the elastic force and deformation relationship of non-yielding devices are, above(3)Formula can be write as:
(6)Formula
With reference to(4)Formula and(5)Formula obtain standard evaluate hitting power expression be:
(7)Formula
If power is non-constant force, and has functional relation with deformation during strike, then(7)Formula is changed
For:
(8)Formula
It is above-mentioned(4)Formula is that standard evaluates hitting power and standard evaluates the basic relational expression of deformation quantity,(5)Formula,(7)Formula and(8)Formula,
For standard evaluate hitting power practical application relational expression, especially with(8)Formula is used as general expression.
