The invention relates to a bullet wall temperature measuring technology, in particular to a bullet wall temperature measuring device for use in a high-overload environment, and a manufacturing method thereof. The problems of poor high-overload resistance, low measuring accuracy, poor continuous data storing capability and high measuring errors existing in the conventional bullet wall temperature measuring device are solved. The bullet wall temperature measuring device for use in the high-overload environment comprises a bullet body, wherein a polytetrafluoroethylene heat-preserving layer is attached to the inner wall of the bullet body; a first installing through hole is formed in the front end of the polytetrafluoroethylene heat-preserving layer in a penetrating manner; a first steel heat-conducting shell and a first polyurethane elastic rubber body are embedded into the inner cavity of the first installing through hole respectively; a second installing through hole is formed in the side part of the polytetrafluoroethylene heat-preserving layer in a penetrating manner; a second steel heat-conducting shell and a second polyurethane bullet rubber body are embedded into the inner cavity of the second installing through hole respectively; a pouring sealant is poured into the inner cavity of the polytetrafluoroethylene heat-preserving layer; and a recorder is embedded inside the pouring sealant. The bullet wall temperature measuring device is suitable for measuring the bullet wall temperatures of bullets.
Description
technical field [0001] The invention relates to a bomb wall temperature measurement technology, in particular to a bomb wall temperature measuring device in a high overload environment and a manufacturing method thereof. Background technique [0002] The temperature of the bullet wall (inner wall temperature) when the bullet hits the target is a key parameter to study whether the material of the bullet body and the electronic fuze can resist the transient strain under high impact conditions. Therefore, measuring and recording the transient change process of the bullet wall temperature under high overload conditions is of great significance for the design of the bullet. Under the existing technical conditions, the bomb wall temperature measuring devices are mainly divided into two types. One of the bomb wall temperature measuring devices uses high-temperature colloid to directly stick a thermocouple on the inner wall of the bomb for temperature measurement. This kind of bom...
