研究了弯纵复合振动驻波振子的振动方程，由纵弯振动方程推导出触头作椭圆运动规律，并进行运动状态分析。提出利用高频转动的椭圆振子代替纵弯振动触头的模拟思路，给出了等同性原理的证明。利用ABAQUS有限元软件对三种驱动模型，各向同性和各向异性两类材料，对不同预压力下的空载速度、阻力和负载特性进行了计算分析，得出在纵向弹性模量相同的情况下，水平弹性模量大的各向异性材料的使用性能更优越。

Mode equations of longitudinal and flexural vibration for hybrid-vibrator were deduced,the el-lipse vibration locus was got,and the location with time domain for tip of vibrator was analyzed. The idea was proposed that ellipse vibrator of high speed rotate substituted the tip of vibrator of ellipse high fre-quency vibration, and the equal principle of their contact drive was proposed. Using ABAQUS FEM sim-ulated three drive model and two kinds of materials which are isotropy and anisotropy, the no-load speed, stop load, load characteristics under different pre-load were calculated and analyzed. A conclusion is drawn that drive performance of anisotropic material which has big horizontal elasticity modulus are good and has the same longitudinal elasticity modulus with isotropic material.
