Disclosed are a tool and a method for measuring a perpendicularity and an angle of a femur of a vehicle crash dummy. The tool includes: a base, where the base is provided with a guide ring gear; and a clamp assembly, where the clamp assembly is configured to clamp a femur part. A measurement assembly can measure the perpendicularity and the angle of the femur part conveniently.

A method for calibrating a chest of a vehicle crash dummy, includes: controlling, under each preset test condition, a pressing apparatus to press down a chest of a target crash dummy with a target pressing speed and a target pressing distance corresponding to the preset test condition, obtaining an actual force-displacement curve under each preset test condition, obtaining a standard force-displacement curve of a chest of a standard crash dummy under each preset test condition, and determining, according to the actual force-displacement curve and the standard force-displacement curve under each preset test condition, whether the chest of the target crash dummy satisfies a biological simulation standard. Through collecting information under various preset test conditions, various complicated conditions of impact on the chest can be more effectively simulated in a crash test by using the method, which improves the accuracy of determining the biological simulation standard.

The present invention discloses a method of filling simulated muscles for a limb of an automobile crash test dummy, the simulated muscles are molded with foaming in the inner cavity of the mold; the method comprises: obtaining a filling volume of the inner cavity of the mold by using a liquid casting method, preparing an adhesive liquid film layer, preparing a filler and conducting demolding detection on the limb. Wherein step 3 is to inject the mixed filler into the inner cavity of the mold so as to be foamed in the mold to form foamed sponge, and stand until the foamed sponge is foamed to the exhaust port and does not overflow any more.

The present invention relates to the field of passive safety testing of vehicles, in particular to a construction method for an impact response performance limit value of a crash dummy and an electronic device. The method includes: determining, according to response curves of the crash dummy under different impact test conditions, a standard response curve and alignment starting time and ending time of each response curve; aligning, according to differences between other response curves except the standard response curve and the standard response curve, other response curves except the standard response curve with the standard response curve; and determining, according to all the aligned response curves, an impact response performance limit value function of the crash dummy, where the differences include cumulative differences or cumulative variances. The method can truly, accurately and effectively construct a performance limit value of a dummy part under various impact tests.
