Part.
Background technique
Currently, the usual way that China's automobile industry rectifies and improves the vehicle that there are problems that smell are as follows: by Odor Evaluations
Member checks all interior trim components of the vehicle by way of subjective assessment one by one, finds the poor components of odor properties simultaneously
It is required that supplier rectifies and improves.This method is primarily present following problems: first, fully rely on the subjective assessment locking smell of personnel
High-risk components, the personal experience for the person of being evaluated and subjective desire influence greatly, to cause result inaccurate；Second, it is odorous to institute
The poor components of performance are all rectified and improved, and rectification is caused to lack purpose, rectification period length and higher cost.
CN201810235259.2 discloses a kind of in-car smell substance and determines method and in-car smell substance source tracing method,
Vehicle emphasis odoring substance is determined using smell phasor, determines high-risk material by calculating matching degree；It is determined using smell phasor
The characteristics of vehicle emphasis odoring substance, this method, is corresponding to carry out odorant concentration with human body olfactory organoleptic stimulation, with gas
Index of the taste intensity as screening vehicle emphasis odoring substance, tests the concentration, olfact and nasal cavity stimulus threshold of different material
It just can determine that vehicle emphasis odoring substance.High-risk material is determined by calculating matching degree, and this method mainly considers different odor object
Difference of the odour intensity specific gravity of matter in vehicle and components.
Summary of the invention
The present invention provides a kind of interior emphasis odoring substance and the high-risk components of smell determine that method, this method can be used for really
Fixed car emphasis odoring substance and the high-risk components of smell；Vehicle emphasis odoring substance is determined using threshold extension rate, passes through meter
It calculates similarity and determines high-risk components.In order to achieve the above objectives, the present invention adopts the following technical scheme:
The present invention provides a kind of interior emphasis odoring substances and the high-risk components of smell to determine method, comprising:
S1: detection vehicle odoring substance: selection needs to carry out certain vehicle that smell is traced to the source, and wants with reference to HJ/T 400-2007
It asks and vehicle air is sampled, volatile organic constituents are analyzed using thermal desorption/capillary gas chromatography/Mass Spectrometry,
Obtained total ion chromatogram and NIST05 standard spectrogram are subjected to matching retrieval, it is qualitative in conjunction with chromatographic retention, it uses
External standard method carries out quantitative analysis, obtains the quantitative analysis results of volatile organic constituents.Aldehyde ketone component using solid phase adsorption/efficiently
Liquid chromatography analysis obtains the quantitative analysis results of aldehyde ketone component.
S2: determine odoring substance olfact: olfact refer to certain substance can cause human body to its nasal receptor most
Small material concentration, it is all with reference to " the measurement triangle odor bag method of GB/T 14675-93 air quality stench " measurement vehicle
Detect the olfact of substance.
S3: it determines vehicle emphasis odoring substance: calculating the threshold extension rate of all detection substances of vehicle, see formula (1).
Di=Ci/CiT (1)
In formula, Di is the threshold extension rate of i-th kind of substance, dimensionless；Ci is the material concentration of i-th kind of substance, μ g/m3；
CiT is the olfact of i-th kind of substance, μ g/m3。
According to the descending sequence of threshold extension rate, using the substance of Di >=0.1 as vehicle emphasis odoring substance.
S4: analysis components odoring substance: certain components of the vehicle are placed in the closed of Temperature and Humidity Control function
In cabin, closed cabin volume is identical as vehicle volume, and components testing conditions are identical as vehicle testing conditions.The same step of detection method
Then S1 determines the threshold extension rate of the odoring substance detected in components according to step S2, S3.
S5: components smell and vehicle smell analysis components smell and vehicle smell similarity: are calculated according to formula (2)
Similarity.
In formula, CD is the similarity of components smell and vehicle smell；N is the quantity of vehicle emphasis odoring substance, DivFor
The threshold extension rate of i-th kind of substance, D in vehicle emphasis odoring substanceipFor the threshold dilution times of the i-th kind of substance detected in components
Number.
S6: determine the high-risk components of smell: the smaller expression components smell of CD value is more similar to vehicle smell, by difference zero
The CD value of component is ascending to be ranked up, and determines the high-risk components of smell according to the ranking results.
The present invention provides a kind of interior emphasis odoring substance and the high-risk components of smell determine method, has below beneficial to effect
Fruit:
(1) determine vehicle emphasis odoring substance using threshold extension rate, the characteristics of this method be using threshold extension rate as
The index of vehicle emphasis odoring substance is screened, only the concentration of different material need to be tested and olfact can determine vehicle emphasis smell
Substance.The emphasis chemical substance and the high-risk components of smell for causing in-car smell are found from objective content of material angle, are avoided
The human factor of subjective assessment influences, so that result accuracy is higher.
(2) high-risk components are determined by calculating similarity, this method mainly considers the threshold dilution times of different odor substance
Difference of the number in vehicle and components.The high-risk components of smell need to only be rectified and improved, so that rectifying and improving have more purpose
And directionality, rectification efficiency is improved, rectification cost is reduced.
