The present application relates to the technical field of
structural mechanics analysis, in particular to a spreader
saddle stress nephogram generation method and
system, comprising the following steps: based on the spreader
saddle regional cable segment force measurement and spatial geometric information, constructing the initial stress of the
saddle body grid, obtaining the
stress concentration rate distribution through homogenization and normalization, extracting the gradient
mutation grid to form a sequence of demarcation points, and generating the saddle area nephogram in the HSV
space mapping according to the non-uniform
color scale. The present application can adaptively identify the area with the most severe
stress change by introducing the analysis of
stress concentration rate and its spatial gradient, and no longer relies on the fixed
color scale division method, but uses the high gradient position as a dynamic
anchor point to construct a non-uniform
color scale sequence. The
processing logic tilts the color scale resolution according to the real stress response of the structure, making the
color transition in the
stress concentration area more fine, and the stress peak and gradient form are clearly presented. At the same time, a wider color scale interval is used in the stress gentle area for general expression.
