多层异构式复合材料飞轮的虚拟设计

Virtual Design of Multi-ring Composite Flywheel Based on Ansys

随着电子计算机技术的不断发展 ,虚拟设计与虚拟制造在机械制造业中所起的作用不断加重。该文基于美国ANSYS有限元处理软件 ,对复合材料飞轮转子进行虚拟设计。复合材料飞轮转子在高速旋转时 ,由于惯性力的作用 ,会产生较大的径向应力和环向应力。若飞轮转子的形状参数、材料参数给定 ,则飞轮在工作时发生断裂破坏只取决于其工作转速的大小(不考虑环境因素及其它意外情况 )。为了有效地避免飞轮转子因超过其极限转速而发生材料断裂破坏 ,本文通过利用AN SYS有限元处理软件的优化设计模块 ,对复合材料飞轮转子的极限转速做初步的预测 ,并给出飞轮转子在该极限转速下的应力分布情况 。

With the gradual development of computer technology, virtual design and virtual manufacture play more important roles in the field of manufacture. In this article, a composite flywheel adopts virtual design based on ANSYS, a software of FEA of the U.S,. When composite flywheel rotates in high speed, there will be greater radial stress and tangential stress because of internal force. Given the shaping parameters and material property, the collapse of flywheel in its rotation mainly depends on rotation speed without considering other factors, such as environment and so on. To avoid the material collapse in composite flywheel for its overextended rotation, here, we make use of the module of optimum design in ANSYS5.7 to predict the ultimate rotation of flywheel, and to find out the stress conditions in this speed. Also the maximum energy storage was given in this case.
