The complex hydraulic valve body in the DCT is an important controlling and influencing factor to realize the function of dual clutch transmission. This paper took a damping hole in the cooling lubricating oil circuit of DCT as the research object, analyzed the flow field of the oil circuit based on the modeling software of CATIA and Fluent, discussed the influence of the size of the damping hole on pressure establishment of the complex valve body related oil circuit, checked the structural design of damping hole in lubricating oil circuit, and proposed the scheme and method of structure optimization. The analysis results after optimization reached the expected inlet pressure of the damping hole, which proved the rationality of the optimized structure.
