The invention relates to a test
bed, which comprises a frame and a first test part for
impact test of an automobile door. The first test part comprises a first
rope pay-off and take-up mechanism, a pull cable mechanism, an elastic mechanism and a first monitoring mechanism, wherein the first
rope pay-off and take-up mechanism is sued for opening an automobile door, the pull cable mechanism is used for unlocking the automobile door, the elastic mechanism is used for applying elastic force to the automobile door to close the same, the first monitoring mechanism is used for monitoring
impact of the automobile door in closing, the first
rope pay-off and take-up mechanism, the pull cable mechanism, the elastic mechanism and the first monitoring mechanism are respectively disposed on the frame, and the first
monitoring system comprises a first angular speed sensor disposed on the edge of the automobile door. The test
bed can be used for precisely controlling
impact speed, so that accuracy of data testing is improved, and reliability of the test
bed is improved.
