A method for determining a modification parameter value of an involute-arc gear, and a product
By employing an adaptive sampling and uniform downsampling purification method based on the Maximin criterion, the problems of low efficiency and insufficient representativeness in the quantitative design of involute-circular arc gear profile modification parameters are solved. This method achieves efficient and stable determination of profile modification parameter values, making it suitable for gear optimization design and intelligent analysis.

Abstract
本发明公开了一种渐开线‑圆弧齿轮修形参数值确定方法、产品，涉及齿轮修形的数字化技术领域。本发明设计了三维设计空间，采用空间抽样配合物理合规性约束筛选以得到可行解。本发明在当前轮可行解数量不足的情况下，引入了依据当前轮可行解对当前轮三维设计空间进行边界收缩、并补偿抽样规模，使固定边界下的盲目搜索转变为面向高概率可行域的聚焦搜索，从而提高了少齿数和强约束工况下的有效样本获取能力与搜索稳定性；在当前轮可行解数量足够的情况下，引入了质心引导下的基于Maximin准则的均匀下采样提纯，能够从大量可行样本中提取出空间分布更均匀、覆盖性更好的代表性解，降低样本局部聚集现象。
