Sample quick assembling and heating system based on plane collision impact test

Abstract

The invention discloses a sample quick assembling and heating system based on plane collision impact test, which includes a launch controller, a gun tube, a central controller, and a heating chamber. The signal line of the central controller is connected to the launch controller. The sample quick assembling and heating system is characterized in that the system further includes an expansion device; the heating chamber is arranged to the side of the mouth of the gun tube; a sample is arranged on the expansion device; the sample moves from the inside of the heating chamber to right opposite the mouth of the gun tube under the action of the expansion device; and the signal line of the central controller is connected to the expansion device and the sample. Compared with conventional collision test, the heating source is changed, the precious open heating source is replaced with the existing closed heating source, the temperature non-uniformity of samples in the heating process is reduced, the heating temperature deviation of the points on a sample is smaller, and a better test effect is achieved.

Description

technical field [0001] The invention relates to the field of high-temperature test of artillery or gas cannon, in particular to design a sample rapid assembly heating system based on plane collision impact test. Background technique [0002] Temperature is one of the important factors affecting the change of physical parameters of materials. In many experiments to study the thermal properties and thermal strength of materials, it is often necessary to establish a specific temperature field. The study of control methods is the core issue of establishing a stable temperature field. PID control is the most widely used control method in process control. As a basic control algorithm, it has been relatively mature and is widely used in industrial process control. This method has the advantages of easy implementation, wide application range, simple parameter setting, and strong robustness, and is widely used in temperature control. At present, the research on the dynamic character...
