Cylinder with multiple diagonal slits is one of the core parts of longitudinal-torsional resonance ultrasonic device. Its structure was more complex, the traditional processing processed it very difficult, and the traditional analytical methods were also difficult to make accurate description to system. The paper researched cylinder with multiple diagonal slits using experimental method, analysis of electrical discharge machining forming tools of the slits and three-dimensional modeling; developed cylinder with multiple diagonal slits, analyzed longitudinal-torsional resonance and mechanical properties of cylinder with multiple diagonal slits using finite element analysis method. Tested resonant frequency of cylinder with multiple diagonal slits with precision impedance analyzer. The finite element analysis results compared with tested results, and analysis of error between them, finite element analysis results slightly lower than the test results but the error was within the allowed range. Comparison of results and analysis of error indicated that developed cylinder with multiple diagonal slits meet requirement.

Abstract. For analyzing the frame whether meets actual driving needs, LCK6105PHENV-type hybrid (electric and gas) city bus frame as research object, using Solidworks12 and ANSYS-Workbench14 on frame, respectively, for the three-dimensional modeling and finite element analysis. Static analysis obtains frame’s stress and deformation results under the condition of bending and reversing (wheels dangling), modal analysis gets frame’s front 6 order vibration type, inherent frequency and the maximum deformation. Analyzing results shows that the frame basically can meet the design requirements, and in line with the actual needs of living and production. This research will provide references for optimization and improvement of new-energy Auto frame.

Microscopic Deformation

The harmonic structure materials consist of coarse-grained areas enclosed in a three-dimensional continuously connected network of ultrafine-grained area. The concept of harmonic structure design has been successfully applied to a variety of pure metals and alloys by mechanical milling (MM) and subsequent powder metallurgy (PM) process. In harmonic structure material, core region with coarse grains maintains a high ductility while the shell region with ultrafine grains contributes for a higher strength. Therefore, the material with harmonic structure design can achieve both strength and ductility simultaneously. In this research, the SUS304L grade stainless steel has been used as a model material to understand and validate the response of the harmonic structure materials towards the applied external loads. The numerical simulation of multi-scale FEA (Finite Element Analysis) was carried out, and it was confirmed that microscopic deformation and the macroscopic tensile strength can be characterized by the present approach.
