Abstract

The invention discloses a dummy hip joint calibration system and method for automobile collision, belonging to the field of automobile safety detection. The system comprises a test table; a dummy hip joint fixing device is arranged on the test table; and a dummy hip joint is fixedly arranged on the test table through the dummy hip joint fixing device. The system further comprises a rocking arm, a force sensor, a rocking arm lifting device and a data processor; one end of the rocking arm extends into a thigh hole of the dummy and is fixedly connected with the hip joint of the dummy; the force sensor is movably connected with the rocking arm; the rocking arm lifting device is connected with the force sensor and is used for applying uplift force to the rocking arm; a comparing module in the data processor compares the stress data of the dummy hip joint acquired by the force sensor with a calibrated standard data, and then the calibration module calibrates the detected dummy hip joint. The system and method provided by the invention can be used for solving the problems that in the prior art, much more sensors are required for the calibration table of the existing dummy hip joint, the calculation is complex and error is easy to cause, and meanwhile, the cost and the maintenance cost are high.

Description

technical field [0001] The invention relates to the technical field of automobile safety inspection, and in particular to a dummy hip joint calibration system and method for automobile passive safety tests. The invention is used to confirm that the performance of the dummy's hip joint meets the standard requirements. Background technique [0002] Automobile crash test belongs to the research category of automobile passive safety, and its purpose is mainly to test the ability of the vehicle to protect the occupants during the collision process. The danger of the crash test makes it impossible to use a real person in the test. Foreign research institutions have manufactured dummies according to the dynamic characteristics of the human body and the mass of each part. of injury. Before the real car crash test, the data inside the dummy may be inaccurate due to various reasons, so the dummy needs to be calibrated. For example, the calibration procedure of the HybridⅢ50% male dum...
