A designing and analyzing system with highly automation and standardization is established combined with VC+ and other programming languages compiling system interface, arranging the process automatically and generating the results automatically.IntroductionThe metal bellows are cylinder-shaped thin section tube whose outside surface presents like ripples, which are generally formed by stainless steel or copper alloy 1. Because of high elasticity in axial direction, the shape can be easily changed when they were pressed in axial direction. Working as connecting and compensating equipment of pipes the metal bellows play aPart in sealing alleviating vibration and noise. Energy-storage compensating heat and isolating materials.Worked as key components in large power stations and military industries，The designing reliability of metal Bellows is highly important. The traditional designing methods are mainly based on CAD methods and the experience of designers 6-7.But the structure of bellows is so complicated that the classic mechanics cannot ca1l slating the stiffness, strength and fatigue life of metal bellows accurately. Nowadays, people genera; use experienced formulas. But experienced formulas are based on experiments of old test-pieces; they are not suitable for new ones. Virtual design technology can improve the reliability and design in productivity, so it becomes to the key point of Bellows designing. In order to improve the designing quality and shorten designing period, the document introduces how to use the software Annoys, MSC. Marc, MSC. Fatigue and UGII integrated to develop a system of Bellows designing.Over all structure of virtual design The unction parameters of bellowsThe capability parameter of the bellows design are stiffness、 stress、 effective are a lose steady, allow displacement、 bearing of pressure and fatigue life and so on. The fatigue life、 stiffness and steady of bellows questions which will be offend faced when designing the sylph on bellows, so the questions must be resolved Perfectly. These performance parameters on the practical application of bellows critical to the performance. This article mainly discusses the bellows stiffness, failure analysis and fatigue life in order to improve the bellows capacity in actual use.Technology roadmap of Virtual DesignAccording to the function parameters of bellows. In this paper, three-dimensional. Modeling adopted modeling adopted Stiffness and Strength Using this Overall process to analyze the designing of sylph on bellows for changing and choosing the correct parameters of bellows. Shown in Figure. LThe overall structure of the virtual design systemUsing VC+ to create a user interface(Shown in Figure.2).According to the technology map of virtual design, we create three-dimensional parameters model of metal bellows by the Secondary envelopment Technology of UGI1. Annoys say ware is Applied to analyze stiffness、strength and structure stress of metal hallows. Afire analyzing results with Annoys, FEA model will be entered into the M which will analyze the fatigue life of bellows. According to the 3D modeling which has met the requirements of stiffness, strength and fatigue life to create the three-dimensional solid model of rr3etal bellows corrugated mold. The three-dimensional solid model will be entered into the MS.Marc which i5 applied to analyze farming which. If the results of amassing a fatigue life and structure stress are acceptable, it will be entered into UG with which the three-dimensional navel will he selected and output the two-dimensional drawings, otherwise repeat the process of designing. The overall function diagram Shown in Figure.3Example of virtual design -Calculation bellows axial stiffness the empirical formula of hellnwss stiffnessStiffness is the force or torque requirement for producing deformation of unit displacer end of the bellows, the resistance for counter turtle which came from the bellows deformation of unit displacement.A recardirig to the carne byre and pressure of the bellows, stiffness sire is one of the parameters which measure the lunatic of bellows. For noun, manufacturers calculate the single-wavelength axial stiffness (fir) by the method of E31v1A, hence comes the axial stiffness of inflation section. This paper adopts the of corrugated metal tube Peoples without Republic of China machinery unreinforced u-shaped bellows industry standard stiffness calculation formula.Bellows material is OOCr17Ni14Mo2;Yield strength for the 230Mpa; Youngs rnodnlus of elasticity of formula the stiffness of iaellvws:Four layers:Calculation of lay Bite element method1) Through the V C+ create user interface e.g. Figure 2 with which the user may enter the analysis interface vfbeliows strength and stiffness.2) Analysis parameters of 6ellvws (e.g. figure 4 and the parameters of bellows material properties can be inputted into the analysis interface of bellows strength and stiffness3) Click the button of analysis, Annoys will automatically call the file .Based on the pararncters which are defined; it will automatically finish the creation of bellows modeling, the division of the establishment of contacts, the imposing constraints. (E.g. figure 5).4) The conditions of load: one end of the car pressed certain displacement. Bellows .The FEA value of bell laws, we must bellows make slated be fixed and the over end should sure that there is no pressure inside in the Tab.2. Stiffness is shown.The concision of the comparison between empirical formula and FEA calculation We can draw out that the results that depend on the empirical formula and FEA calculation are roughly the same through the example of calculating the axial rigidity of the bellows it FEA calculation, it allows us TV reduce the experimental test when we analyze a new test specimen.SummaryThe document introduced how to use the software Annoys, MSC. Marc, hrISC.Fatigue and UGI1 integrated to develop ritual design system of Bellows designing. Based on the system which can he used to design parametric bellows and analyze the stiffness, strength, and shaping process and fatigue life of metal bellows. Metal Bellows of high quality can be designed in less tire e and rainy.References1Haitian CSUU: Tue manufacture and application of bellows components (Machinery Industry Press 1998.7)2 Republic of China National development and Reform Commission: Republic of China Machinery Industry Standard metal bellows(JB/T6169 一 2006).3 Shuguang Gong and Guilan die: ANSYS operation command and Parametric Prflgrarnrning (Machinery Industry Press 2004.)4 Changchun Jiang, The Finite Element Analysis Of Bellows Used In Metal Bellows Mechanical Seals (2007).5 Lee.
