Description
Technical field
The invention belongs to the ergonomics technical field, particularly a kind of platform for testing biomechanical characteristics of human body position in automobile.
Background technology
In modern society, along with popularizing of development and national economy and automobile, automobile is not only as people's the vehicles, the extension in people living space especially.Investigate discovery according to the Britain scientist, the disease that is sitting in the people Chang You in the automobile for a long time is because the angle unreasonable, that seat is incorrect to the distance adjustment of pedal and the back tilts of armchair structure is unreasonable.Above factor all can be summed up as automobile and take advantage of and drive the unreasonable of Environment Design (claiming people's car INTERFACE DESIGN again), automobile is taken advantage of and is driven the important step of environment space design as the vehicle design, have direct relation with the comfortableness of taking advantage of frame and security, therefore also more and more be subjected to people's attention.
Conventional people's car INTERFACE DESIGN method is mainly based on human body podomere kinematics and geometry, the ergonomics aspect is a foundation with comprehensive and subjective qualitative conclusion, empirical rule, how much contiguity constraints such as comfortable and fatigue of people mainly then, the scientific law of the rare consideration person of driving body biomechanics characteristic.Owing to lack quantitative calculation and analytical approach, the degree that makes the result of people's car INTERFACE DESIGN be difficult in biology and biomechanics is surveyed the space and is satisfied human body and take advantage of the demand of driving comfortableness, especially is difficult to the requirement of satisfying personalized (referring to monomer individual character or group syntality).From the analysis of biomechanics, if people's car contact interface design makes the human body body press irrational distribution, then can cause the local compression of human body skin layer, then can cause fatigue phenomenons such as human body is tingle for a long time; If the design of people's car contact interface makes the backbone form unreasonable, then can cause human body back discomfort and pain, and then very easily cause human-body fatigue, bring out the driving occupational illness; If handling the interface, people's car make human muscle's force mechanism, size unreasonable, can make the muscle that continues to shrink oppress blood vessel, and then stop blood to enter muscle, when the human muscle can't obtain sufficient oxygen by blood, then easily cause human muscle's fatigue, and cause the human muscle to ache.Secondly, present ergonomic design lacks the consideration of man-machine individual character, and the driving of automobile product is exactly towards individuality, though at present general Automobile Design has the function at adjustable interface, but just solved the part man-machine problem, take advantage of the guidance of driving position biomechanics characteristic science data owing to lack automobile, the problem of man-machine contact interface just can't be resolved from mechanism.
Traditional ergonomics is mainly carried out corresponding people-car contact interface design according to the statistics of anthropometry, carry out corresponding people-car according to some empirical datas of human-body fatigue statistics and handle interface and mode of operation design, really do not solve automobile and take advantage of the comfortableness problem of driving and take advantage of the fatigue problem of driving from mechanism.The relevant comfortable body biomechanics problem of driving of taking advantage of, Chinese scholars has been carried out more exploratory research work, studies relation between cushion material characteristic and the stress intensity as Silver-Thom by the interfacial pressure measurement.Pearson discusses the influence of action of muscles to interfacial stress distribution by research technique.Tobias etc. have set up the finite element model of human body lumbar vertebrae, by this model analysis the biomechanics characteristic of lumbar vertebrae when pressurized of human body, this model also can be used for the stability analysis of lumbar vertebrae.Goel analyzes and simulates the motion of the stressed of human body thoracic vertebrae and waist ligament by Finite Element Method.Oxland has studied the biomechanical issues of human synovial.Canada M.Kolich tests the comfortableness of 5 kinds of compact automotive seats by 12 indexs, research points out that the comfortableness of automobile contact interface is a new research branch, and existing human engineering design criteria based on anthropometry can not be applicable to the design of automobile people-car contact interface.At present, the problem of relevant car steering fatigue is also carried out a lot of research work both at home and abroad, studied joint power and partes corporis humani as people such as China Liu Rong and divided relation between the degree of fatigue.The Li Zengyong of Shanghai Communications University, king become cover from ergonomics angle analysis-by-synthesis cause the environmental factor of driving fatigue, point out that visual interface, sense of hearing interface, people-seat interface, people-operation interface are the main man-machine interfaces that influences driving fatigue, and proposed to prevent and alleviate the effective measures of driving fatigue from the design of automobile man-machine interface.Above research does not incorporate the body biomechanics specificity analysis in method for designing and the theory, proposes corresponding method for designing with theoretical.
The variable seat of Japan's exploitation is characterized in sitting posture and each the position stressing conditions that can simulate various types of seats and measure tested personnel.The automotive seat body of Tsing-Hua University is pressed Distribution Test system, be used for the pressure distribution situation on testing automobile seat people-chair surface of contact, its objective is that the thoroughly evaluating for the seat driving comfort provides an objective basis, test result also can be applied to instruct design simultaneously, press distribution performance or under the prerequisite that does not influence driving comfort, save the seat cushions material as far as possible to reach better body.In Related product, also there is not an example that human engineering and biomechanics are merged, study quantitative human engineering method.
