The mathematics model of travelling-wave ultrasonic motors is studied in this paper and the equivalent vibrating model is built.
对行波超声电机的控制模型进行了研究，并建立了等效动态振动模型。

While numerical modelling of surface travellingwave absorption performance was feasible, without experimental data, calibration of any such simulation model was not possible.
即便没有试验数据，表面行波吸收性能的数值也是可以模拟的，但是不能校准这些模拟数值。

At this time the simulator does not implement surface travellingwave modelling and associated edge or gap backscatter modelling, or edge diffraction scattering effect modelling.
