Abstract

In order to solve the problems of rapid temperature change in explosion field and harsh test environment, a transient temperature acquisition recorder with small size and high linearity is developed. A Ktype thermocouple adaptation processing circuit integrating cold junction compensation, temperature and voltage linearization, and a singlechip programmable logic device to realize the miniaturization of the 8channel recorder are designed. Use AUTODYN software to carry out a numerical simulation study on the secondary explosion temperature of aluminumcontaining explosives. The temperature data obtained by the numerical simulation and the temperature data measured by the experiment are compared and analyzed. The results show that the peak of the reaction stage is 14. 5 m and 15 m from the explosion center. The absolute value of the temperature measurement error is within 5%, and the absolute value of the peak temperature measurement error in the postreaction stage is within 20%, which verifies the feasibility of the test system and realizes the accurate measurement of the transient temperature of the explosion field.

Key words： transient temperature; aluminum-containing explosive; explosion field; thermocouple; acquisition and storage system
