Evaluation And Analysis Of Car Seat Comfort Based On The Measurement Of Body Pressure Distribution

With the continuous development and progress of science,technology and the global society and economy,the luxury cars are more and more popular.The car seat is one of the important parts associated with the car.The comfort of car is becoming more and more importance to people.In order to improve the comfort of the car and meet different people's requirements,this paper puts forward "Evaluation and analysis of car seat comfort based on the measurement of body pressure distribution".And study the evaluation of the car seat comfort and the hardware and software implementation of seat comfort test system.According to the designed for car seat comfort,relevant guidance is put forward,which has the good engineering significance.In this paper,the seat comfort test system and the evaluation criteria are introduced,the evaluation system of the comfort analysis is established,and the seat comfort of the three vehicles is analyzed by the evaluation system.The main work of the paper includes:(1)The paper presents the test system and evaluation criteria of car seat comfort.According to different type seats,in this paper,by means of the building comfort testing system,analysis of different type seat to be used in different environmental pressure,as a comfort evaluation,introduces several common comfort evaluation standards,introduces the commonly used international standard ISO-2631.Based on the method of subjective evaluation and objective measurement,the difference of force distribution between the seats of the low-grade car and the premium car seat is analyzed.(2)The hardware and software implementation of seat comfort test system is studied.Analyze the selection and layout of stress measurement point,introduce the signal acquisition module detailedly and use the hardware system of acquisition of human body pressure distribution using CONFORMat software with the result of typical model data acquisition are analyzed.(3)Use the body pressure distribution test system and analysis software CONFORMat for the three models of seat comfort test,to analyze the pressure distribution.Find out the shortage of the independent brand seat design and improves the seat comfort parts,realize the independent brand seat comfort is close to or better than the premium ca.The experimental research shows that the comfort level of the low-grade car seat pressure curve is close to the level of premium car.
