Harmonic Response Analysis

At present, development of manufacturer’s ultrasonic cleaning tank (UCT) to match the requirements from consumers usually relies on computer simulation based on harmonic response analysis (HRA). However, this technique can only be used with single-frequency UCT. For dual frequency, the manufacturer used information from empirical experiment alongside trial-and-error methods to develop prototypes, resulting in the UCT that may not be fully efficient. Thus, lack of such a proper calculational method to develop the dual frequency UCT was a problem that greatly impacted the manufacturers and consumers. To resolve this problem, we proposed a new model of simulation using transient dynamics analysis (TDA) which was successfully applied to develop the prototype of dual frequency UCT, 400 W, 18 L in capacity, eight horn transducers, 28 and 40 kHz frequencies for manufacturing. The TDA can indicate the acoustic pressure at all positions inside the UCT in transient states from the start to the states ready for proper cleaning. The calculation also reveals the correlation between the positions of acoustic pressure and the placement positions of transducers and frequencies. In comparison with the HRA at 28 kHz UCT, this TDA yielded the results more accurately than the HRA simulation, comparing to the experiments. Furthermore, the TDA can also be applied to the multifrequency UCTs as well. In this article, the step-by-step development of methodology was reported. Finally, this simulation can lead to the successful design of the high-performance dual frequencies UCT for the manufacturers.

Frame is an important truck part to connect and support engine, transmission, carriage and cab etc. It is important to analyze strength, stiffness and dynamic characteristics for frame design. This paper developed static analysis of a specific agricultural truck frame under two conditions of full load bending and reverse. The corresponding suggestions of structural modification were proposed. Then the dynamic response of truck frame caused by the external incentives was studied, namely harmonic response analysis and transient dynamic analysis. The paper not only analyzed whether the truck frame met the strength requirements, but also proposed the corresponding solutions for the possible cases of fatigue fracture and stress overloaded of the frame.

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.
