Description
Technical field
The invention belongs to car consumption credit experimental technique field, a kind of competing product vehicle performance quickly side of analysis is particularly related to
Method.
Background technique
When rotating left and right vehicle because of centrifugal force generation transversal force, because of the seat that occupant keeps original in order not to make body skew
Appearance, resists the effect of transversal force, and the muscle condition of body everywhere is become nervous reflectingly.
Trunk is sat on the seat, and foot is placed on floor and pedal, steering wheel is held, at this point, these positions are all limited.But
It is, as long as head not being not to protect the musculi colli anxiety of supporting head part there is no limit that can move freely as long as intentional pillow is attached to headrest above
Hold appropriate location.Although trunk and foot are because people's difference restrictive condition also changes, muscular tone condition also changes therewith, because of branch
There is no limit muscular tone condition is the same for the musculi colli in fastener portion.Neck of people or so respectively has a chest lock mastoid process muscle, this
Muscles is the main muscles of supporting head part lateral position.
Requirement in recent years to the ride comfort of automobile is higher and higher, and ride comfort is one of most important essential elements of evaluation of vehicle,
The performance of vertical direction, shadow of the Vehicle Lateral Motion Based to human body can only be judged the measurement of vehicle offset frequency and acceleration equivalent averages
Sound can only but be analyzed by subjective assessment.
Due to the number of the experience of the driving of driver, to degree of attentiveness, the language difference used of vehicle etc., to the row of vehicle
Evaluation result and the expression for sailing performance are all kinds of, never objectively comment well about before the driving performance of vehicle
Valence determination method.
Before doing new product development, it is often necessary to carry out performance evaluation to the different competing product vehicles of many different manufacturers, mark post vehicle.
Using traditional subjective assessment, a large amount of evaluation personnels, but also long period are not only needed, evaluation lacks objectivity.
