Multi-objective optimization of forging process para-meters of TC4 titanium alloy connecting rod based on orthogonal experiment
为了实现连杆热锻过程的绿色设计，基于Deform-3D平台，采用正交试验法与数值模拟相结合的方法对热锻成形过程中的TC4钛合金连杆进行多目标优化。以锻坯初始温度、锻造速度、压扁量、摩擦因子四个工艺参数作为影响连杆性能的因素，探究其对能耗、最大成形载荷、变形均匀性以及最大等效应力4个评价指标的影响规律。通过直观分析以及极差分析确定较优方案，借助综合频率分析法得到TC4钛合金连杆最优工艺方案，并对优化前后的连杆质量以及能耗进行了对比分析。通过研究发现…查看全部>>
In order to realize the green design of connecting rod hot forging process, based on Deform-3D platform, the method of orthogonal experiment and numerical simulation was used to optimize the TC4 titanium alloy connecting rod in hot forging process. Four process parameters, including initial forging temperature, forging speed, flattening amount and friction factor, were taken as factors affecting the performance of connecting rod. The influence rules of four …查看全部>>
