Design Of Shared Car Cab Based On Analysis Of Concentration And Sitting Posture

The use of shared cars has effectively alleviated the pressure of urban environmental pollution and energy shortages,and alleviated many social problems of urban traffic congestion,parking difficulties,and high cost of vehicles.Through the design and research of the urban shared car cab,the thesis hopes to better improve the driving safety of users,improve the driving experience of primary users,and reduce the traffic accidents caused by human factors.The thesis conducts an inductive analysis of past studies on the static dimensions of the human body,explores the connection between the user’s sitting posture and concentration,and optimizes the spatial layout of the city’s shared car cab.First,analyze the relationship between the user’s driving sitting posture and driving concentration,and build a simulated driving platform based on Eyeso eye tracker to study the sitting posture factors that affect driving concentration,and obtain the human sitting posture parameters that improve the user’s driving concentration.Secondly,through the sitting posture experiment to determine the driver’s comfortable driving sitting posture under the best concentration situation,the subjective scoring table is used to obtain the comfortable angle of each joint.Furthermore,combining the above experimental data,a two-dimensional planar human body model is established with computer assistance.Analyze the static size and dynamic size of the sitting posture of the two-dimensional flat mannequins of the 10th percentile female,50th percentile male,and 99th percentile male respectively,and obtain city sharing on the basis of ensuring user comfort Car cab parameters and build a cab model.Finally,the application of CATIA to establish a human-machine-environment system for the 10th percentile women,the 50th percentile men and the 99th percentile men’s visual field of view,visual comfort,and reachability and comfort Assessment to verify the rationality of the layout of urban shared car cabs.The paper establishes a complete experimental method for sitting posture to affect the user’s concentration,obtain effective parameters,and improve driving safety.Through computer-aided analysis and research,the user’s driving posture is adjusted to improve driving comfort,which solves the contradiction between driving safety and comfort in previous studies.The use of computer two-dimensional graphics group to realize the simulation of human-machine dynamic data,constructs a simple and intuitive,effective design method for the dynamic space design of the cab,and proposes a new idea for the follow-up research of the product design of shared cars.The thesis research has positive significance for the promotion of shared cars,so that shared cars can better serve the public and provide a new way for urban green and safe travel.
