Test verification method, device and equipment for engine air passage

The embodiment of the invention discloses a test verification method, device and equipment for an engine airway, and the method comprises the steps: obtaining a casting model of an engine cylinder cover, and inputting the casting model into casting simulation software to obtain the deformation condition of the casting model; and obtaining an engine cylinder cover correction model according to the deformation condition, and printing an engine airway solid model in the engine cylinder cover correction model by using a selective laser sintering printing technology. And then entity parameters of the entity model are obtained and compared with the design parameters. And when the comparison result is that the entity parameters are inconsistent with the design parameters, the casting process of the casting model is adjusted according to the comparison result, so that the casting model or the engine cylinder cover correction model is adjusted. According to the method, the deformation condition of the cylinder cover c
