车门密封条消耗能量计算

Automotive Door Seal Consumption Energy Calculation

摘要:

根据密封条在关门过程中的工作原理，通过质量守恒定律和动量定理,建立车门密封条及其排气孔的数学计算模型.基于Excel平台,利用VBA语言,使用数值积分与循环迭代方法，设计人机交互操作界面，计算密封条的消耗能量.通过对排气孔消耗能量的研究，可以得到排气孔阻尼力消耗能量占密封条消耗总能量的20%，所以,排气孔消耗能量是密封条消耗总能量中不可忽视的重要影响因素.比较不同车型的计算结果与试验数据，误差均不超过12%，证明计算是有效的.

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.
