s parameter value may by the experiment metrical data fitting.May use the different unit construction in view of th。 The friction element corresponds to the movement vicebetween friction。s rubber bush elastically and so on bined action effect。s physical part and the influence shock absorber characteristic actual factor has certain corresponding relationships: The elastic element corresponds in the throttle valve is the elastic element, the fat liquor or the fuelair mixture condensibility, the cylinder tube39。 (b) increased a friction element Psi。s development, oneself has the possibility to use has FSI (fluidstructure interaction, class solid coupling) analyzes the function the finite element analysis tool to solve the shock absorber fluid solid coupling nonlinear dynamics question. parametrization modelIn the late 80s, Karadayi and Masada reveal Lang the model, although can express the shock absorber well the nonlinear response, but too plex, is not suitable uses in the automobile systems dynamics and the vibration simulation analysis. In order to establish one kind both to be able to express the shock absorber sluggish characteristic and a more concise model, they used equivalent have changed into the shock absorber by the elastic element, the damping element, the gap and the friction element and so on mechanical model which bined. In the model does not consider the shock absorber the actual structure and the interior work process. Part39。s amount of deformity, the discharge coefficient and so on must obtain by the experiment test. From the establishment model mostly tests the result using the experiment to obtain partial or the plete model parameter, therefore is not advantageous in the design stage forecast shock absorber characteristic.Along with putation technology39。s model must express between the cavity indoor fat liquor pressure and the piston kinematics parameter relations, usually must consider that the fat liquor the condensibility, it is causes the shock absorber velocity characteristic to present the sluggish phenomenon the substantial clause. The pensated chamber model must express between its internal fat liquor pressure and the volume relations. If the consideration gas mixes in the fat liquor to cause the shock absorber characteristic to give rise to the distortion problem, then needs to establish various cavities room fuelair mixture to have the physical change to cause the pressure volume characteristic to change the model. According to the mass flow conservation equation, relates various cavities room and throttle valve39。s current capacity with its both sides pressure difference39。s characteristic expression for valve39。s some double barrelled like suspension fork shock absorber39。s characteristic has the decisive influence regarding the shock absorber characteristic. Shock absorber internal throttle valve willowy valve piece bination, cushion valve piece and helical spring bination, plate valve and helical spring bination and so on. Its elastic element39。s distortion and so on real active status, establishes the fluid and the structure coupling dynamics model, this kind of model already may use in the shock absorber characteristic forecast and the analysis, may also use in the automobile systems dynamics and the vibration simulation analysis. The equivalent parametrization model bees the shock absorber some to have abstractly some mechanics characteristic typical physics part39。s research, has established three kind of mathematical models, namely parametrization model, equivalent parametrization model and nonparameter model. The parametrization model had considered the shock absorber interior fat liquor39。s damping element, its performance to rides fortableness, the handling quality and so on to have the direct influence, its mathematical model39。 } }}附 錄二 外文資料Barrel fluid strength shock absorber performanceanalog simulation technology development1. shock absorber mathematical model39。 (false)。namespace qiaoli{ static class Program { /// summary /// 應(yīng)用程序的主入口點。using 。 || (byte)() == 8) { } else { = true。) || == 39。 = 39。 amp。 } } private void textBox5_KeyPress(object sender, KeyPressEventArgs e) { if (( = 39。.39。939。amp。039。 || (byte)() == 8) { } else { = true。) || == 39。 = 39。 amp。 } } private void textBox3_KeyPress(object sender, KeyPressEventArgs e) { if (( = 39。.39。939。amp。039。 || (byte)() == 8) { } else { = true。) || == 39。 = 39。 amp。 } private void textBox1_KeyPress(object sender, KeyPressEventArgs e) { if (( = 39。 (80, new Font(宋體, , ), , 6, 20)。 (60, new Font(宋體, , ), , 6, 100)。 (40, new Font(宋體, , ), , 6, 180)。 (20, new Font(宋體, , ), , 6, 260)。 (ε, new Font(宋體, , ), , 326, 340)。 (4, new Font(宋體, , ), , 244, 340)。 (2, new Font(宋體, , ), , 124, 340)。 (0, new Font(宋體, , ), , 4, 340)。 (pen1, 5, 60, 8, 60)。 (pen1, 5, 140, 8, 140)。 (pen1, 5, 220, 8, 220)。 (pen1, 5, 300, 8, 300)。 (pen1, 245, 340, 245, 337)。 (pen1, 125, 340, 125, 337)。 (pen1, 5, 0, 10, 6)。 (pen1, 340, 340, 332, 345)。 (pen1, 5, 0, 5, 340)。 Pen pen1 = new Pen(, 2)。 Graphics g = (bmp)。 //(X: + +,Y:+)。 //if (() == ) //{ // string fileload = 。 //OpenFil
