THERMAL RESPONSE OF THE PART 572 DUMMY TO STEP CHANGE IN AMBIENT TEMPERATURE

Tests have been conducted measuring the thermal response of components of the assembled Part 572 dummy to step changes in ambient temperature. A series of four tests was conducted. Ambient temperatures ranged from 62 to 120F, and both heating and cooling experiments were performed. The response of the test dummy was measured in an environmental chamber with continuous air circulation. Of the seven dummy locations monitored, the data obtained consistently shows the forehead location to respond most rapidly and the lumbar spine location to respond most slowly to ambient temperature change. Data for the forehead and lumbar spine locations is reduced in the form of plots of a dimensionless temperature variable vs. time. Least squares fits to these data sets are computed and are presented for predictive purposes. Analysis of the data indicates that a single function is adequate to fit both heating and cooling responses at the forehead location.
