It simulates response to impacts , , deflections , forces and moments generated during a . Transducers in the provide the physical levels experienced by the dummy . These readings are controlled and repeatable due to careful dummy and manufacture so that the designer may use them to perfect the safety of his product . Data for development of the responses of the dummy has come from human physiological in sub - injury non - lethal crash simulation ; from data derived from with PMHS ( post mortem human subjects ) ; from data based on physical properties tests of tissue from PMHS supplemented with data from animals . Thus the crash test dummy representing many sizes and ages and with the capability to be used in different crash orientations offers the designer a , repeatable test for the furthering of safety .
