ABAQUS is become in punch form is finite yuan of application in imitate

The application of the ABAQUS software that article place shows saved the cost that products plan develops successfully, still can shorten at the same time the time that designs development, and simulative result and actual result apart are not big, it is the outstanding software of a rare. One, the cost in imitate treatment process is managing treatment figuration technology is production industry is medium a kind of main technique. Current, production industry machines craft forward the way of hi-tech develops, more and more companies are in product research and development and the application that begin to pay attention to emulation technology in production process. Using ABAQUS to undertake emulation simulative purpose is managing development cost, accelerate research and development speed and improve product quality. ABAQUS can be aimed at different operating system (like Unix, linux and Windows) undertake stand-alone or much chance run paralell operation, save more operation time. Below with ABAQUS the door design of some car user is exemple, demonstrative ABAQUS shapes in punch finite yuan of application in imitate. If the graph is shown 1 times,traditional door designs circuit. Graph the traditional design technological process of door of car of 1 some model basically designs among them reach finished cost to be as follows: 1.

The design of soft qualitative mould and finished cost are 200 thousand dollar; 2.

The cycle that initial stage is produced and revises a mould is general not under 12 weeks; 3.

The design of horniness mould is revised and finished cost is 750 thousand dollar; 4.

Of plan of final product trial production, mould finalize the design, the cycle that Cheng Zhi of correction pull current reachs to be produced formally is 8~9 commonly month. Among them, the design charge of horniness mould is included in early days soft qualitative mould designs charge in, later period is calculated only the charge that modification mould designs. After using ABAQUS to undertake the number is emulated, if the graph is shown 2 times,design circuit. Graph after the 2 design effects of door of some model car after introducing ABAQUS modify design technological process, main design and finished cost are as follows: 1.

The design of soft qualitative mould and finished cost are 100 thousand dollar; 2.

The cycle that initial stage is produced and revises a mould shortens it is 4 weeks; 3.

The design of horniness mould is revised and finished cost is 250 thousand dollar; 4.

Of plan of final product trial production, mould finalize the design, the cycle that Cheng Zhi of trial production, correction pull current reachs to be produced formally is commonly 3.

5~4 month. Course above computation can see clearly, only the design charge of door is managing 2/3, and design cycle shortens for original 1/3. 2, the numeric imitate of the process of difficulty treatment figuration in process of imitate treatment figuration gets material geometry is nonlinear, nonlinear with the combined influence with nonlinear border, direct calculative difficulty is very great. From the point of mechanical essence, very much figuration process can simplify to follow static course, to this process finite yuan imitate has two kinds of methods normally: Method of type of static force concealed and motivation are explicit method. According to motivation the principle of flabby law, the stable state solution of dynamical system and static uptake are consistent. So article place involves calculate exemple all use explicit kinetic method, although use ABAQUS/EXPLICIT to seek solution implement module, to different treatment figuration process undertakes imitate. Calculate exemple make clear, ABAQUS can get satisfactory result in handling treatment figuration. 3, apply actually 1.

The punch figuration of common gasoline tank the strike out of this example imitate gasoline tank process. The graph shows the figure of the half that is the gasoline tank when shaping actually 3 times. Considering in strike out process, the symmetry of gasoline tank structure, the article pursues through imitate 3 left next shows structures, undertake to its imitate is analysed, achieve the goal that analyses whole gasoline tank to shape. Above all, complete a plan through ABAQUS/CAE 3 on the right side of shows assembly drawing, among them planar aluminium board will be shaped to be a graph by punch 3 left the structure below. The whole process of figuration is shown 4 times like the graph, imitate result follows be identical of photograph of actual production process. Among them, the graph shows the metabolic curve of the internal energy in be whole process and kinetic energy 5 times, process of OK and affirmatory imitate is accurate static state. Graph the ply that of 6 expression is the plate after shaping distributings cloud atlas. Graph 7 gave out to change with ply the ply that 4 unit and relevant node of the largest part are in the metabolic curve inside time-domain. Pursue 　 of 　 　 of the structural imitate graph of 3 gasoline tank and 　 of 　 of 　 of 　 of 　 of 　 of 　 of assembly drawing 　 pursues strike out of 4 gasoline tank form process sketch map 　 of 　 of 　 of 　 of 　 of 　 of 　 of 　 　 　 pursues the metabolic curve 　 of the internal energy in 5 whole processes and kinetic energy.

Process of imitate of the strike out of the plank of alloy of titanium of strike out form of titanium alloy plank ABAQUS is shown 8 times like the graph. Graph the ABAQUS imitate process that 8 punch shape 3.

Meng Lacheng form is unconscious if the graph is shown 9 times,play shaping ABAQUS simulation. Graph 9 unconscious pull shaping ABAQUS imitate sketch map to pursue the metabolic curve of 10 moulds stress 4.

If rubber pocket figuration and figuration of rubber pocket of Ban gold figuration and Ban gold figuration pursue 11, graph 12, the graph is shown 13 times.

Figuration of bent housing of bent housing figuration is shown 14 times like the graph. Graph 14 bent housing shape ABAQUS imitate sketch map 6.

If figuration of round Taper Pipe of figuration of round Taper Pipe pursues 15 are shown. Graph the ABAQUS imitate sketch map that 15 conic canals shape 4, the imitate of conclusion above example undertakes below ABAQUS platform. The result makes clear, use ABAQUS to handle treatment to shape what what involve in the process is nonlinear mechanical problem, can get comparative satisfactory result. In addition, ABAQUS still offerred phyletic and rich user subprogram port, the user unit that the user can write this special compose relation curve, complex load and attrib border condition and agile diversity according to need, in researching domain and industrial field at present, these functions were obtained apply widely.
