一种用于火焰响应测试的速度扰动产生装置
By using piezoelectric devices to drive a vibrating plate to generate velocity disturbances, the problem of flame response testing devices being unable to operate under high temperature and high pressure environments has been solved. This has resulted in a miniaturized and modular disturbance generation device suitable for combustion devices operating under high temperature, high pressure, and limited space.

AI Technical Summary
Existing flame response testing devices cannot work effectively in high temperature and high pressure environments, and traditional loudspeakers are large and heavy, making them difficult to install in precision combustion devices with limited space.
A rigid piezoelectric device drives a vibrating plate to generate velocity disturbances. Harmonic signals excite the piezoelectric device to generate deformation, causing the vibrating medium to generate velocity disturbances in the flame response tester. This method is suitable for high temperature and high pressure environments.
It enables flame response testing under high temperature and high pressure conditions. The device is small in size and light in weight, suitable for installation in compact spaces, and has frequency response characteristics and modular adjustment capabilities.
