摘　　要：为解决螺杆转子的复杂曲面加工问题,采用增材制造技术对螺杆转子进行了轻量化结构设计。为验证轻量化螺杆转子设计的合理性,利用Fluent和ANSYS软件对空压机螺杆转子进行了不同工况下的双向流固耦合和热力场耦合数值模拟研究。在双向流固耦合数值模拟过程中,通过对不同出口空气压力和转子转速下的螺杆转子的数值模拟,获得不同工况下的螺杆转子的形变发展趋势。在热力场耦合数值模拟过程中,同时考虑温度约束条件和加载转矩载荷,获得轻量化螺杆转子随转速的形变规律。提供了一种对空压机螺杆转子进行多场耦合力学特性分析的结构优化设计新思路,也对其他结构复杂产品的智能制造提供了重要参考。In order to solve the problem of complex surface machining of screw rotors,this article adopts additive manufacturing technology to design a lightweight structure for screw rotors.In order to verify the rationality of lightweight screw rotor design,the numerical simulation of two-way fluid-structure coupling and thermodynamic field coupling of air compressor screw rotor under different working conditions was carried out by using Fluent and ANSYS software.In the process of bidirectional fluid-structure coupling numerical simulation,the development trend of screw rotor deformation under different working conditions is obtained by numerical simulation of screw rotor under different outlet air pressure and rotor speed.In the process of thermal field simulation,temperature constraints and torque loads are simultaneously considered to get the deformation principle of the rotor with speed.This article provides a new approach to structural optimization design for multi field coupling mechanical characteristics analysis of screw rotors in air compressors,and also provides important references for intelligent manufacturing of other complex structural products.
