“…1 The structure of the acoustic lining assembly [7] For making multi-holes, various techniques such as mechanical drilling, laser beam, punching, ultrasonic machining and EDM have been developed. Punching has high efficiency, stable dimensions, and unlimited hole patterns, but it's hard for punching to process non-plastic materials such as carbon fiber [10,11]. EDM supplemented by spray cooling can realize the processing of carbon fiber materials, and effectively solves the dust problem in traditional machining [12,13].…”

Acoustic lining assemblies with millions of high-density array holes are key structures for highperformance and low-noise aero engines. However, the material specificity, variable curvature shape structure, high-order number of holes, and small-sized hole spacing of acoustic lining assemblies pose great challenges to the hole-making technology. In this paper, in view of the machining requirements of millions of acoustic lining holes, a hole matrix unit design method for batch hole making is proposed. The optimal hole matrix unit dimension is calculated with the angle deviation of normal vector as the constraint by matching the structural features of the acoustic lining assembly, dividing and interpolating the hole-making surface, and solving the normal vector of the hole position. The experimental results shows that the proposed hole matrix unit design method can effectively control the angle deviation of normal vector of the acoustic lining holes and ensure the processing accuracy of the holes.

To observe the dynamic mechanical response and investigate the processes of high speed stamping for C5191 phosphorus bronze, tensile tests of C5191 phosphor bronze under quasi-static tensile condition at a strain rate of 0.001 s-1 by electronic universal testing machine, and dynamic tensile tests at strain rates of 500, 1000 and 1500 s-1 by split Hopkinson tensile bar (SHTB) apparatus were performed. The dynamic tensile properties and deformational mechanism were investigated by SEM and TEM. The results show that the yield strength and tensile strength of C5191 phosphor bronze under high strain rates increase by 32.77% and 11.07%, respectively compared with quasi-static condition, the strain hardening index increases from 0.075 to 0.251, and the strain rate sensitivity index for material strength changes from 0.005 to 0.022, which presents a clear sensitivity to strain rates. The deformation resistance increases with the increasing of the strain rate due to the stronger short range resistance induced by the acceleration of dislocation motion. The ability of plastic deformation of C5191 phosphor bronze increases due to the number of movable dislocations increase significantly, multi-line slip start, and the soft effect of adiabatic temperature rise at the strain rate ranging from 500 to 1500 s-1 .
