Harmonic Response Analysis

Modal analysis of machine center was carried out by means of finite-element analysis (FEA) method to get its characteristics and to improve its machining precision. Based on this, harmonic response analysis was processed to evaluate its vibration when the cycle load caused by the machining force was applied on the main shaft of machine center, which was used to provide clues for avoiding resonance vibration and ameliorating design.

Harmonic Response Analysis

A finite elementmodel of a 9-meter-high wind-solar hybrid powered street light was established;statics analysis, modal analysis and harmonic response analysis were performedusing ANSYS. Static analysis determined the maximum deformation and stress of astreet light under complex load, and checked its intensity and rigidity. Modalanalysis and harmonic response analysis obtained a vibration mode of a streetlight and its natural frequency of every order. The results of analysesprovided references for the optimization of street light structure.

Finger Tip

Based on the requirements of that the finger can move in parallel, and the displacement of the finger can be detected, the micro-gripper driven by piezoelectric actuator is designed based on the displacement amplification structure with the flexure hinge. The static analysis, the modal analysis, the harmonic response analysis and the transient response analysis of the micro-gripper are carried out by using the finite element analysis software ANSYS. The results of the finite element analysis show that the finger is fully able to move in parallel, and can detect the displacement of the finger; the maximum displacement of the finger is about 101 μm, the first natural frequency is about 130 Hz; the finger tip displacement under the 1 μm step input is about 20 μm, the fingertip vibration is about ±2 μm.
