Normally, the workover rig platform is obtained only low order natural frequency by modal analysis. In order to understand the frequency response of structure dynamic load, we well carry out harmonic response analysis on the operation platform in this paper. On this basis, determine the modal frequency that is greatest effect on dynamic behaviour of the workover rig operation platform structural system. To extract the modal frequency as dynamic optimization goal or state variables.Finally, achieve forecast the possibility of dynamic interference between operation platform and other components.

The CAD software SolidWorks was used to create a three-dimensional finite element model of FTIR infrared spectrometer, and the model was imported into ANSYS/Workbench to modal analysis and harmonic response analysis. Through modal analysis, each order natural frequency and vibration shape were obtained. From modal shape analysis, all components of the stiffness strength and elastic deformation situation were got, and many times tests were carried to enhance stability of the structure and materials which had the most seriously deformation and direct effect impact to the quality of interferometer. The most sensitive frequency range of the system was concluded by harmonic response analysis, which provided a basis for further designing and improving of the spectrometer performance.

A successful prediction that whether a compressor blade is able to overcome the resonance fatigue and fatigue life of forced vibration is based on its harmonic response analysis.Hard coatings with metal or ceramic substrate are effective to change the natural characteristics and vibration amplitude of a compressor blade so that to improve the anti-vibration fatigue capability. In this paper, modal analysis and harmonic response analysis based on the finite element method are achieved to investigate the contributions of the two different hard coatings on the natural characteristics and vibration amplitude of a compressor blade. The two kinds of hard coatings are modeled by both anisotropic materials and involving their piezoelectric or piezomagnetic effects. The blade is modeled as an isotropic one. The natural frequencies and vibration amplitude of blade with different coating thickness are numerically calculated and compared. Results show that the hard coatings with different thickness play an important role in the natural characteristics and harmonic response analysis of the blade.

Harmonic Response Analysis

Abstract. To make vehicles more reliable and efficient, many researchers have tried to improve the rotor performance. Although certain achievements have been made, the previous finite element model did not reflect the historical process of the motor rotor well, and the rigidity and mass in rotor optimization are less discussed together. This paper firstly introduces fractional order into a finite element model to conduct the harmonic response analysis. Then, we propose an optimal design framework of a rotor. In the framework, objective functions of rigidity and mass are defined, and the relationship between high rigidity and the first-order frequency is discussed. In order to find the optimal values, an accelerated optimization method based on response surface (ARSO) is proposed to find the suitable design parameters of rigidity and mass. Because the higher rigidity can be transformed into the first-order natural frequency by objective function, this paper analyzes the first-order frequency and mass of a motor rotor in the experiment. The results proved that not only is the fractional model effective, but also the ARSO can optimize the rotor structure. The first-order natural frequency of asynchronous motor rotor is increased by 11.2 %, and the mass is reduced by 13.8 %, which can realize high stiffness and light mass of asynchronous motor rotors.
