Abstract

The invention discloses a high-precision schlieren system light path adjusting device and a use method thereof, and belongs to the field of power machinery. A high-precision schlieren system light path adjusting device is characterized in that a laser emitter and a laser receiver are horizontally arranged, the laser emitter emits horizontal laser, the laser receiver receives the horizontal laser, and a constant volume bomb is parallel to the horizontal laser; wherein one schlieren instrument, the constant volume bomb, the optical sensor and the other schlieren instrument are sequentially arranged in the direction parallel to the horizontal laser, an incidence window and a perspective window of the constant volume bomb correspond to one schlieren instrument and the optical sensor respectively, the light source irradiates one schlieren instrument, and the camera corresponds to the other schlieren instrument. The signal output end of the optical sensor is connected with the signal input end of the computer. According to the invention, the precision problem of the schlieren method is solved, the optical sensor can be moved without changing the whole optical path, and the whole is not affected. The system is low in cost, high in reliability, convenient and high in overall perfection degree.

Description

technical field [0001] The invention relates to an optical path adjusting device of a high-precision schlieren system and a method for using the same, belonging to the field of power machinery. Background technique [0002] In the research field of internal combustion engine visualization technology, the two most commonly used methods are MIE scattering method and schlieren method. The schlieren method has important visualization applications because it can display the invisible flow field inside the constant volume bomb. significance. For the study of schlieren method, there are many kinds of optical paths in schlieren method, such as Z-type optical path, T-type optical path and BOS method optical path. [0003] At present, in the process of visualization of internal combustion engines, the requirements for accuracy are getting higher and higher, and the realization of accurate information collection is the highlight of the current visualization technology research process...
