Abstract The automated fiber placement (AFP) technology has drawn considerable interest to replace the traditional hand laid‐up, providing greater productivity, precision, repeatability, reduced waste, and capability manufacture complex curved structures. To further advance application level of AFP, it is essential exert extraordinary efforts in process planning. In this paper, a collaborative planning method incorporating conditions manufacturing constraints first developed described...
Aging treatment plays a significant role in altering the mechanical properties of superalloys; however, influences aging on performance Rene 41 alloy and its strengthening mechanisms remain unclear. In this study, effects microstructure forged were systematically investigated through experimental theoretical analyses. It was found that conditions have grain structure, γ′ characteristics, tensile alloy. The size secondary increased from 20 nm to 69 with elevated temperature prolonged time,...
A multi-objective optimization method was proposed for different dome reinforcement methods of a filament-wound solid rocket motor composite case based on Radial Basis Function (RBF) model. Progressive damage the considered in simulation Hashin failure criteria, and results were validated by hydraulic burst tests to precisely predict mode, position, pressure. An RBF surrogate model established evaluated Relative Average Absolute Error (RAAE), Maximum (RMAE), Root Mean Squared (RMSE), R2...
Currently, there is limited research on the in situ forming process of thermoplastic prepreg tape winding, and unclear impact parameters mechanical properties during manufacturing becoming increasingly prominent. The study aimed to investigate influence composite materials (CFRP) using laser-assisted CF/PPS winding technology. melting point decomposition temperature were determined DSC TGA instruments, based operating equipment, parameter range for this fabrication technology was designed. A...
The effects of a solution treatment on the microstructure and elevated mechanical properties forged Rene 41 superalloy were investigated. results indicate that temperature has significant influence γ′ structure properties. sub-solvus resulted in co-existence residual primary coarse precipitates fine secondary precipitates, while super-solvus treatments led to complete dissolution precipitation nano-sized spherical precipitate. tensile strength increased then decreased when from treatments....
Base frame calibration is the foundation for cooperative work of manipulators. The commonly applied method usually constructed a matrix equation. contact-mode approach limited by insufficient accuracy and efficiency while high cost impedes application methods with noncontact mode. In this paper, projection-based proposed. All transformation parameters can be solved based on geometric constraints. When manipulators form closed-chain asynchronously, topological structure projected into...
Obtaining reliable winding paths for non-axisymmetric shapes with current filament technologies is still a challenge. In this study, an algorithm was developed generating geodesic and non-geodesic that are slippage- bridging-free can be applied to axisymmetric as well mandrel models represented by triangular meshes. By performing stability analysis on the path curved surface, non-slipping non-bridging conditions mesh deduced. Then, according inverse process of analysis, next point satisfies...
Summary Studies on the effect of different shape strategies wind‐induced responses super tall buildings have been extensive. However, little systematic research influence aerodynamic shapes wind pressure distributions high‐rise building having a height more than 500 m is reported in literature. In this paper, series tunnel tests are conducted models simulating tapered taller with an aspect ratio 9:1 by applying synchronous measurement technology to investigate force coefficients cross...
The filament winding method is widely used to manufacture lightweight, strong, composite products. To reduce time, the of by band, which consists several roving tows, used. A computer numerical control machine with input path commands for precise operation. Before winding, users should verify simulation that appropriate without any erroneous Furthermore, prior starting operation, usage length each tow must be checked because manufacturing process stops unexpectedly if on creel runs out. In...
The vibration characteristics of composite vertical stabilizer skin structures play a critical role in damping effects designed for overcoming the air disturbances experienced by aircraft structural components during flight. first-order fundamental frequencies and their corresponding structure tow-steered automatic fiber placement technique were optimized with parameterized trajectories plies as design variables. Firstly, numerical models derived based on Kirchhoff laminate theory,...
