结果表明，驱动桥壳空心梁和半轴套管部分的应力远小于材料的许用应力，而悬架支座与桥壳连接处出现了局部应力过大的情况。
The results show that stress in hollow beam and semi-shaft bush is much less than permissible stress, while joint of suspension frame and axle housing has too large local stress.
模拟结果表明，该微动作器的第一模态频率远低于第二模态，镜子的位移由梁的扭转引起。
The simulation shows that the first mode frequency for performance is near 1000Hz, which is much lower than that of the second mode. The displacement of mirror is caused by the torsion of beam.
