The door is an important part of the aircraft structure.The door test is an important means to verify that the door design meets the requirements of reliability,safety and airworthiness.There are design verification tests and certification tests for doors of civil airplane.Based on the experience and lessons of civil airplane doors′development,the necessary test items and contents during the civil airplane doors′developing process are summarized in this paper.The purpose,significance and necessity of each test are pointed out,the design of test benches and the simplified designing principle of test-pieces are proposed,and the methods and steps of the tests are given.The research in this paper has certain reference value for the door design to meet the requirements such as function and performance,use requirements,continuous airworthiness requirements and to formulate a reasonable test plan in the design stage.
