Abstract:

For the inaccurate analyses of automotive door closing force simulation caused by assembling deviations,a approach to accurately calculate the door closing force was proposed.Firstly, by establishing appropriately mechanics model of the components in the process of closing the door, the door lock that impacted the closing force out of several other factors was taken for example, and the probability statistics distribution of door lock's positional errors in the process of assembling was gained by Monte Carlo simulation.Combined with the door lock's positional assembling errors in the calculation of the closing force of the mathematical model, the probability distributionof the door closing force was obtained. Then the closing force tests on the prototype were done.The test results show that the calculation accuracy of the door closing force that combined with the door assembling deviations is improved.
