It applies example and this is no longer repeated one by one.
Fig. 2 is the flow chart that a kind of body noise provided by the embodiments of the present application determines method, referring to fig. 2, this method packet
Include following steps.
Step 201: terminal obtains the initial body noise acoustic pressure of object vehicle, at least one sheet metal component pair in object vehicle
The material thickness variable quantity and sensitivity coefficient answered.
Since under normal conditions, the noise of automobile can not only damage physical and mental health by bus, and it is rapid to will lead to driver
Fatigue, confusion of thinking, dispersion attention etc., to cause various traffic accidents.Therefore, in order to avoid noise is to passenger
Damage, and the interference to driver, it usually needs in a certain range by the noise control of automobile.It and is usually in vehicle
The stage of exploitation determines the noise of automobile, with determine whether by the noise control of automobile in a certain range.And it is opened in vehicle
When the hair stage determines automobile noise, it usually needs obtain some parameters.Therefore, the initial vehicle body of the available object vehicle of terminal
The corresponding material thickness variable quantity of at least one sheet metal component and sensitivity coefficient in noise acoustic pressure, object vehicle.
Wherein, terminal obtain the corresponding material thickness variable quantity of at least one sheet metal component in object vehicle and operate can be with are as follows:
It receives body noise and determines request, determine in request and carry the corresponding material thickness variable quantity of at least one sheet metal component；Alternatively, display ginseng
Number input interface, and when display parameters interface receives parameter confirmation instruction, the material thickness carried in parameter confirmation instruction is become
Change amount is determined as the material thickness variable quantity of at least one sheet metal component.
Due to that usually design department may be needed to cooperate with emulation department when carrying out the noise of object vehicle, because
This, the body noise that terminal may receive other equipment transmission determines request.Again since emulation department and design department can
Same terminal can be will use, therefore, when it needs to be determined that object vehicle body noise when, terminal can show the input of parameter
Interface, staff can confirm by specifying the corresponding material thickness variable quantity of at least one sheet metal component of operation input, and in triggering
After instruction, terminal can get the material thickness variable quantity of input from confirmation instruction.The specified operation can be input operation, point
Hit operation, slide, voice operating etc..
In addition, the material thickness variable quantity usually floats within a preset range, which can be arranged in advance, for example, should
Preset range can just expect thick 10%, 5% etc. for sheet metal component, and the first thickness of expecting of the sheet metal component is each sheet metal component first
Value in beginning design scheme.
Since the material of sheet metal component is thick different, the corresponding sensitivity coefficient of sheet metal component is also different, therefore, when at least one metal plate
When the material thickness of part changes, terminal not only needs to obtain the corresponding material thickness variable quantity of at least one sheet metal component, it is also necessary to obtain
Sheet metal component currently expects thick corresponding sensitivity coefficient.
Wherein, which can change according to the corresponding material thickness variable quantity of at least one sheet metal component from the material thickness being previously stored
Measure sensitivity coefficient corresponding at least one sheet metal component is obtained in the corresponding relationship between sensitivity coefficient.Alternatively, terminal can
To determine corresponding sensitivity coefficient in real time according to the material thickness variable quantity of at least one sheet metal component.
It should be noted that terminal obtains the operation of the initial body noise acoustic pressure of object vehicle, and according at least one
The thick variable quantity of the material of a sheet metal component determines that the operation of corresponding sensitivity coefficient can be implemented with reference to the relevant technologies, the application in real time
Example no longer repeats this one by one.The initial body noise acoustic pressure refers to that vehicle body of the object vehicle in preliminary design scheme is made an uproar
Several pressures.
Step 202: terminal is based on initial noisc acoustic pressure, the corresponding material thickness variable quantity of at least one sheet metal component and sensitivity
Coefficient determines the body noise acoustic pressure of object vehicle.
After being changed due to the material thickness of at least one sheet metal component in object vehicle, the body noise acoustic pressure of object vehicle can
Can change, therefore, terminal need based on initial noisc acoustic pressure, the corresponding material thickness variable quantity of at least one sheet metal component and
Sensitivity coefficient determines the body noise acoustic pressure of object vehicle.
Wherein, terminal is based on initial noisc acoustic pressure, the corresponding material thickness variable quantity of at least one sheet metal component and sensitivity system
Number determines that the operation of the body noise acoustic pressure of object vehicle includes at least the following two kinds mode.
First way, terminal can based on initial noisc acoustic pressure, the corresponding material thickness variable quantity of at least one sheet metal component with
And sensitivity coefficient, the body noise acoustic pressure of object vehicle is determined by following first formula.
Pj=P0+nλi*Δti (1)
It should be noted that in above-mentioned first formula (1), PjFor body noise acoustic pressure, P0For initial noisc acoustic pressure, n is
The number of at least one sheet metal component, λiThick corresponding sensitivity coefficient, Δ t are currently expected for i-th of sheet metal component in n sheet metal componentiFor
The material thickness variable quantity of i-th of sheet metal component.
It should be noted that i-th of sheet metal component can be any sheet metal component at least one sheet metal component, or material
The thick maximum sheet metal component of variable quantity, or to expect the smallest sheet metal component of thick variable quantity, or other legal metal plates
Part.It that is to say, terminal can change according to the corresponding sensitivity coefficient of any sheet metal component at least one sheet metal component with material thickness
Amount, by above-mentioned first formula (1), determines body noise acoustic pressure, can also be according to the thick variable quantity of material at least one sheet metal component
The corresponding sensitivity coefficient of maximum sheet metal component and expect that thick variable quantity determines body noise sound by above-mentioned first formula (1)
Pressure.
The second way, terminal can determine the material thickness mean change of the corresponding material thickness variable quantity of at least one sheet metal component
The sensitivity mean coefficient of amount and the corresponding sensitivity coefficient of at least one sheet metal component；It is thick flat based on initial noisc acoustic pressure, material
Equal variable quantity and sensitivity mean coefficient, determine the body noise acoustic pressure of object vehicle.
It is influenced in various degree since the variation of different sheet metal component material thickness has the body noise acoustic pressure of object vehicle, because
This, in order to improve determining object vehicle body noise acoustic pressure accuracy, terminal can first determine the thick mean change amount of material and
Sensitivity mean coefficient is then based on initial noisc acoustic pressure, expects thick mean change amount and sensitivity mean coefficient, determines target vapour
The body noise acoustic pressure of vehicle.
Wherein, terminal can be based on initial noisc acoustic pressure, the thick mean change amount of material and sensitivity mean coefficient, by following
Second formula determines the body noise acoustic pressure of object vehicle.
