This invention relates to the field of cable-stayed bridge technology and discloses a wind-resistant catwalk system for a spatial cable suspension bridge. The system module assembly includes a wind tunnel module, a static wind analysis module, and an optimization design module. The wind tunnel module analyzes the aerodynamic parameters of the catwalk through a scaled-down model wind tunnel three-force experiment, analyzing the influence of different permeability rates on these parameters, providing support for static wind stability analysis and buffeting response calculation. The static wind analysis module, based on wind tunnel test data and combined with a finite element model, calculates the critical wind speed for static wind instability of the catwalk, and analyzes the displacement and internal force distribution of the catwalk under different wind speed gradients based on the influence of geometric nonlinear effects on stability. Based on the analysis results of the static wind analysis module, this invention adjusts structural parameters, optimizes the permeability rates of the side and bottom netting, reduces the span, and adds horizontal and inclined stay cables or external cables to improve structural stiffness and reduce vibration amplitude, proposing a reliable wind-resistant system design.

The present disclosure provides a display optimization method, device, electronic equipment, storage medium and program product. In the display process, a target sub-pixel in the current display area can be determined. In 3D naked eye display, light is split by a grating to form a first view (for example, a left eye view) and a second view (for example, a right eye view). The two views correspond to the target sub-pixel, which may correspond to two luminances, i.e. the first view luminance and the second view luminance. At this time, the final target luminance of the target sub-pixel can be determined according to the luminance difference between the first view luminance and the second view luminance, in combination with the position of the target sub-pixel. The target luminance formed on the basis of this reduces the span of left and right luminances, makes the R, G and B point light matching uniform, solves the sawtooth and color stripe problems of the image edge, and improves the user experience.
