Research on Evaluation Criteria of Seat Headrest Shake Based on DOE
The seat headrest shakes when driving,which significantly reduces the user experience and affects the user's willingness to buy a car.The current evaluation is difficult to reflect the actual level of seat headrest shake.This paper identifies the influencing factors of subjective evaluation and standardizes them.At the same time,for the shake acceleration test,the test process is standardized from the aspects of sensor selection,pasting,measurement and signal processing;the key factors affecting shake are screened by design of experiment(DOE)method,and the consistency and effectiveness of subjective and objective evaluation are proved based on the correlation analysis of DOE results,and the regression equation of subjective and objective evaluation indicators is established,formulate the acceleration standard value of headrest shake to guide the acceptance evaluation of seat headrest shake.
