摘　　要：凸轮轴铸件成品的质量既受到多个铸造工艺参数组合的影响,又极易受到环境中噪声因素所产生误差波动的影响。基于此,田口方法中的信噪比概念与多目标决策中的TOSIS被应用于凸轮轴铸造过程工艺参数的优化中,以实现铸件质量的鲁棒性设计。结合铸造过程计算机数值模拟技术,从仿真试验方案中得到了具有强抗干扰能力的最优工艺参数组合。试验结果表明:铸型温度35℃,浇注时间12 s,浇注温度1446℃的铸造工艺参数组合,使凸轮轴铸件的质量既可靠又具备鲁棒性,为实际生产中铸造工艺参数的优化方法提供了思路。The quality of camshaft castings is affected not only by the combination of multiple casting process parameters,but also by the error fluctuation caused by noise factors in the environment.Based on this,the concept of signalto-noise ratio in Taguchi method and TOPSIS in multi-objective decision-making were applied to the optimization of process parameters in camshaft casting process,so as to realize the robust design of casting quality.Combined with the computer numerical simulation technology of the casting process,the optimal combination of process parameters with strong anti-interference ability was obtained from the simulation test scheme.The test results show that the casting process parameters of casting mould temperature 35℃,pouring time 12 s and pouring temperature 1446℃ make the performance of camshaft casting reliable and robust,which provides an idea for the optimization method of casting process parameters in actual production.
