The invention discloses a rapid pressure relief and thermo-acoustic vibration comprehensive stress simulation test device which comprises a rapid pressure relief simulation part and a thermo-acousticvibration simulation part. The rapid pressure relief simulation part mainly comprises a controlled pressure relief box, a rapid pressure relief pipeline and a pressure control pipeline; and the thermo-acoustic vibration simulation part comprises a vibration table base body, a vibration table top, a box body, an acceleration sensor, an infrared lamp array, a high-power loudspeaker, a gathering walland a plug. According to the rapid pressure relief and thermo-acoustic vibration comprehensive stress simulation test device, pressure stress, thermal stress, noise stress and vibration stress can besimulated at the same time, the design of the gathering wall and the plug are designed, so that a local high-strength sound field can be formed near a test piece; and a two-pipeline controlled pressure relief mode is adopted, so that the pressure intensity in the controlled pressure relief box is ensured to be accurately controlled in time.

    本发明公开了一种快速泄压及热声振综合应力模拟试验装置,包括快速泄压模拟部分和热声振模拟部分;其中,快速泄压模拟部分主要包括受控泄压箱、快速泄压管路、控压管路;热声振模拟部分包括振动台基体、振动台台面、箱体、加速度传感器、红外灯阵、大功率扬声器、聚拢壁、堵头;本发明可同时模拟压强应力、热应力、噪声应力、振动应力;采用聚拢壁和堵头设计,可以在试验件附近形成局部高强声场;采用两套管路受控泄压的方式,确保受控泄压箱体内压强及时准确受控。
