Door System Stiffness and Error Analysis Considering Fixtures
摘要
Abstract
As prediction accuracy was not high,and deviations were large for finite element simulations and tests,a new door stiffness analysis method was proposed,which considered test fixtures.Using theory of limit error synthesis,experimental error model was established by coupling test data collection errors and flexible deformation errors.A method was gave based on sensitivity analysis to calculate importances of error effects considering different station fixtures,and the common form of simulation error transfer model was deducted.Finally,results show that the fixture has a great influence on deviations between tests and simulations,and verifies accuracy of the error model in an example of a car door.关键词
