Abstract

基于有限元分析的方法,结合镍基高温合金的材料特性和增材制造工艺特点,对提出的几种激光增量制造内应力控制方式进行了数值模拟分析。模拟结果表明,提出的几种内应力控制方式如:单点预热应力控制方法、激光表面扫光内应力控制方法、基于环境温度的内应力控制方法及先分区成形再整体连接的内应力控制方法,都可有效去除激光增材制造加工过程中产生的内应力,几种方式简单易行,具有较强的工程实际意义。

Other Abstract

Based on the finite element analysis method, and combined with the Inconel 625 nickel -based alloy's material properties and process characteristics, several stress control methods of laser melting additive manufacturing are analyzed. The simulation results show that the internal stress can be removed by the four control methods, which are the single point of preheating stress control method, surface sweeping by laser stress control method, based on the internal stress of environment temperature stress control method, and the partition formed first, then the whole connection stress control method. The control methods are simple and have strong significance in the field of engineering.
