Automotive Door Seal Consumption Energy Calculation

Abstract:

The working principle of seal was analyzed and mathematical models of seal and its venting holes were set up by the application of mass and momentum balance equations.Seal consumption energy was calculated and man-machine interface was designed based on software Excel,VBA language,numerical and iterative methods.Through studying consumption energy of seal venting holes,consumption energy of seal venting holes damping force is 20% of seal total consumption energy.So consumption energy of seal venting holes is important influencing factors of seal total consumption energy.The calculation results are compared with the test data in different models that error less than 12% proves the calculation effectiveness.

Key words:automotive door; seal; consumption energy; venting holes
