摘要：为提高空间直线度评定精度，建立了空间直线度数学模型。采用变步长天牛须搜索算法对目标函数进行求解，主要包括天牛须搜索及变步长等步骤。针对原始天牛须搜索算法求解精度不高，易陷入局部最优等问题，设计变步长方法，增强算法多样性，从而充分提高计算精度。对其进行求解，并根据终止准则得到计算结果，将该寻优结果与其他方法的评定结果相比较，验证了该算法的可行性及优越性。

Abstract:In order to improve the accuracy of spatial straightness assessment，a mathematical model of spatial straightness is established.The objective function is solved by using a variable step length beetle search algorithm.It mainly includes the steps of the search and step length of the beetle.The precision of the original search algorithm is not high，and it is easy to fall into the local optimal problem.The variable step length method is designed to enhance the diversity of the algorithm and improve the calculation precision.The solution is solved and the calculation results are obtained according to the termination criterion.Compared with the results of other methods，this optimization result verifies the feasibility and superiority of this algorithm.
