摘　　要：介绍了90MN单动卧式铝挤压机的主要技术参数和结构特点,对挤压机前后梁进行了有限元数值模拟优化分析,得到了前后梁的应力应变分布;对挤压筒进行了热力耦合有限元仿真分析;介绍了液压控制系统的集成技术,介绍了电气控制系统的主要组成。实验表明前后梁应力分布合理,挤压筒受力状况良好,液压电气控制系统稳定可靠。The main parameters and structural characteristics of 90 MN horizontal single-action aluminum extrusion press have been introduced in the text. The FEM analysis of front and back platen has been carried out. The stress and strain distribution of front and back platen has been gained. The thermo-mechanics coupling analysis has been conducted to extrusion container by FEM simulation. The integrated technology of hydraulic control system has been introduced, as well as the main composition distribution of front and back platen is reasonable and of electric control system. The experiment shows that the stress the stress on the extrusion container is fine. The hydraulic andelectrical control system are stable and reliable.
