Embodiment Construction
[0066] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0067] Such as figure 1 As shown in , a method for generating compliant mechanisms based on continuous deformation of zero-genus mesh surfaces includes the following steps:
[0068] 1) Initialize the zero-genus grid surface and configure the initial component layout; set a series of vertex coordinates and connect the vertices to form geometry, and the parameterized geometry is further divided into smaller triangular grids to form the initial component layout described by the grid surface; Given the thresholds of triangle mesh refinement operation and splitting operation, respectively 25% and 30% of the shortest side of the design domain; set the upper limit of material consumption to 20%, set the maximum number of iteration steps to 1000, and the convergence standard for variable changes is 0.001;
[0069] When the triangular mesh surface is used for topolo...
