Abstract
Laser shock processing (LSP) is a new surface strengthening technology, it can produces relatively large residual compressive stress on the metal surface and a certain depth, and refines the grain on the metal surface, so as to strengthen the metal. In this paper, the stress distribution and deformation of thin blade edge of TC17 titanium alloy under multi-point impact were studied by numerical simulation. By controlling the action distance of plastic wave, the process parameters of single-sided laser shock strengthening of thin blade edge were designed. The results show that the solution time of dynamic shock is 10000 ns according to the energy curve. By changing the boundary constraints of thin blade, such as bottom constraint, cantilever constraint and both ends constraint, to simulate the actual processing situation, the distribution of residual stress in bottom constraint is the most uniform, the increase of residual stress in the processing area is more obvious, and the material deformation is the least. Based on the commonly used processing parameters of 3 mm laser spot and 20 ns pulse width, 30% overlap ratio is adopted to avoid uneven impact or excessive local stress. The residual stress is about 104, 247 and 450 MPa when 2, 3 and 5 J energy are used respectively; the blade edge deformation is controlled at about 4 μm. In this paper, the actual multi-point machining is simulated, which provides a theoretical reference for the selection of the actual machining parameters of thin blade.
