摘　　要：为实现竹胶合板模板力学性能的优化,以竹胶合板模板纵、横方向的静曲强度和弹性模量作为力学性能优化评价的基本指标,运用正交试验与数值模拟相结合的方法,构建了竹胶合板模板工艺参数和力学性能指标的二阶响应面模型。基于该响应面模型,利用Pareto遗传算法对竹胶合板模板力学性能进行多目标优化,获得了10个Pareto解。通过对10个Pareto解与初始值力学性能进行比较与分析,结果表明:纵向静曲强度平均提高了12.80%;横向静曲强度平均提高了14.75%;纵向弹性模量平均提高了14.11%;横向弹性模量平均提高了8.59%。In order to realize the mechanical properties optimization of bamboo plywood form,the quadratic response surface model of process parameter and mechanical properties,i.e. modulus of rupture （MOR） and modulus of elasticity （MOE）in both parallel and perpendicular directions,of bamboo plywood form was set up using orthogonal experiment and numerical simulation. Based on the response surface model,multi-objective optimization of mechanical properties of bamboo plywood form was carried out by the Pareto genetic algorithm,and 10 Pareto solutions were obtained. Comparing the 10 Pareto solutions with the initial value mechanical properties,the results showed that the MOR values in parallel and perpendicular directions increased by 12.80% and 14.75%,respectively;while the MOE values increased by 14.11% and 8.59% respectively.
