Abstract：This paper establishes an evaluation system of armrest comfort with four evaluation indexes， and deduces that the armrest pressing tactile index is the key index of linear correlation through the linear regression model. Further， through the quadratic regression and linear regression model， this paper analyzes the relationship between the handrail pressing force deformation curve and the handrail pressing touch， obtains the relationship and analyzes it in combination with practice， which has practical reference significance for automobile enterprises to optimize the technical development and design of door handrail.

Key words：multiple linear regression， quadratic regression， linear regression， handrail pressing force deformation curve
