9632173 Ge This GOALI project develops a computer-aided methodology for synthesis of low-harmonic trajectories that would reduce the potential of vibration and related control problems of high-speed machinery. In addition,it formulates a trajectory-pattern methodology for optimal design of high-speed machinery. Collaborative research work is performed with OmniTek Research and Development, Inc. of Brooklyn, NY under the Faculty-In- Industry aspect of the GOALI program. Polynominal and spline curves have been widely used for planning motions of computer controlled machinery. The resulting trajectories, when expressed in Fourier series, generally indicate a considerable number of harmonics with high frequencies in the actuator coordinate system. The presence of such high frequency harmonics in the trajectory is a significant source of the internal induced vibrations. It is the reduction of these vibration excitations in high-speed machinery that is addressed in this research project.***

9632173 Ge 该 GOALI 项目开发了一种计算机辅助方法，用于合成低谐波轨迹，从而减少高速机械振动和相关控制问题的可能性。此外，它还制定了高速机械优化设计的轨迹模式方法。 合作研究工作是与纽约布鲁克林的 OmniTek Research and Development, Inc. 在 GOALI 计划的业界教员方面进行的。多项式和样条曲线已广泛用于计算机控制机械的运动规划。当以傅里叶级数表示时，所得轨迹通常表示致动器坐标系中具有相当数量的高频谐波。轨迹中存在的这种高频谐波是内部诱发振动的重要来源。本研究项目致力于减少高速机械中的这些振动激励。***
