AI Technical Summary

Technical Problem

Existing technologies lack a calculable chain from input parameters to external support design when designing A-frame ladder supports, resulting in long R&D cycles, insufficient reproducibility and auditability, and the determination of external support dimensions relies on experience and repeated experiments, making it difficult to achieve a stable and consistent model.

Method used

By inputting parameter data of the A-frame ladder, including platform height, horizontal loading force, total weight, half width without external support, anchor point height, lateral stiffness, and vertical stiffness, the minimum external support length and geometric effective seat angle are calculated using redundancy processing and simulation software data to form closed boundary conditions and optimize the external support design.

Benefits of technology

This enables the determination of key design quantities such as the external support length in one go during the design phase, reducing trial and error, shortening the R&D cycle, improving the pass rate of stability testing, and forming a consistent model of design-manufacturing-testing.

Abstract

The invention belongs to the field of data processing, and provides a method, a system and equipment for optimizing external support stability parameters of a herringbone ladder, and the method, the system and the equipment are obtained by dividing a horizontal loading force by lateral rigidity after lateral outward movement is used as redundancy, and an extension-free effective half width is obtained by subtracting lateral outward movement from an external support-free half width; the minimum torque overhanging is a non-negative part of a difference value obtained by subtracting an overhanging-free effective half width from a required half width, and the minimum anti-sliding overhanging is obtained by multiplying a tangent function of a direction margin angle by an anchor point height; and judging whether the parameters of the herringbone ladder need to be optimized or not according to whether the maximum value of the minimum torque extension and the minimum anti-sliding extension is within the extension constraint interval or not. Therefore, design-manufacturing-testing can be unified, trial and error are reduced, and the stability and the one-time passing rate of a type test are improved.
