The invention discloses a hydraulic manifold path design method based on SLM forming technology. Analyze the structural parameters of the initial model, and screen out the parameters to be optimized in the initial model; determine the hydraulic manifold with the minimum pressure loss along the structure as the optimization goal, and take the overall weight of the structure, natural frequency, stress concentration, wall deformation, The strength safety and working temperature are constrained conditions, the optimization objectives and constrained conditions are analyzed to determine the convergence conditions and the number of iterations, the structure is optimized by using an optimization algorithm, and the final design result of the hydraulic manifold is obtained. The invention fully utilizes the advantages of the SLM forming technology, improves the utilization rate of materials and the utilization efficiency of devices, and the structure and performance of the hydraulic integrated block will step up to a new level.
Description
technical field [0001] The invention relates to a design method for a hydraulic manifold, the field of integrated hydraulic systems and the field of metal additive manufacturing, and in particular to a path design method for a hydraulic manifold based on SLM forming technology. Background technique [0002] The hydraulic manifold is one of the key components in the integrated hydraulic system. Its structural design mainly meets the requirements of internal communication and layout of external valve components. The traditional design method and machining production will cause the process cavity and the hole to shrink suddenly ( Expansion), heavy quality and other problems, have gradually been unable to meet the system requirements. The wide commercial application of SLM molding technology provides new ideas and solutions for industrial production design and solving complex structure manufacturing problems, but it needs to be clear that China is still in a state of Inside the...
