Study on the testing of the accelerated point of the floating fiber in the roller drafting process with an improved method

The dynamic motion of floating fibers in the drafting process, which can be characterized by fiber accelerated points, has an important effect on the sliver or yarn quality. In this study, the fiber accelerated point during the roller drafting process has been tested with an improved method. In this method, tracer fibers and standard tracer yarns of known length were embedded into the sliver in groups. By adjusting the length and fineness of the standard tracer yarns, it was possible to determine the nip line of the front roller dynamically. Therefore, the fiber accelerated points can be obtained in a continuous drafting process without an external sensor, which is simpler and more convenient, and avoids the experimental error caused by the drawing frame shutdown during the experiment. Based on this method, the effects of the drafting parameters and sliver properties on the fiber accelerated point in the roller drafting process have been investigated. In addition, the coefficient of variance of the sliver ( CVFAP) caused by the fiber accelerated point variation during the drafting process was also calculated. A comparison has been made between CVFAP and the standard deviation of the fiber accelerated points. It is found that a fairly good agreement between these two is seen, and this agreement can also evidence the accuracy of experimental results about the fiber acceleration point.

Penciptaan Film Animasi “Chase!” Dengan Teknik “Digital Drawing”

A short animation that combines several personal experiences and surroundings into a simple yet entertaining story. Although the story is presented simply, visualization is made unique and flexible with digital two-dimensional animation techniques. This animated film is titled “CHASE!” Which means chasing, taken from the core of the film which tells the story of a young man who chases a mysterious woman who turns out to be a transvestite.The animated film “CHASE!” Lenght 3 minutes 45 seconds, make the story made shorter and directly to the point at the core of what will be delivered. The number of shots reached 45 shots with a total of 5400 frames of HDTV 1920 x 1080 px 24 fps (frames per second). In the process of making this film also applied 12 principles of animation. Making an animated film “CHASE!” uses a digital process in it. For animating, 2D drawing frame by frame technique are used digitally by using computers, background images are also digitally created without leaving the artistic value of traditional drawing techniques using hands.Keywords: Film, 2D Animation, Personal Experience, Digital

Fiber motion and the accelerated point distribution in roller drafting

In this study, the tracer fiber method was used to determine the accelerated point distribution in both the break draft and main drafting zone of the drawing frame with varying different draft parameters. Viscose, cotton, and polyester slivers were used respectively. For the different parameters, the tracer fibers of known length were embedded in the single sliver strand, and measurements of their positions before and after drafting were taken. These measurements of the positions of tracer fibers before and after drafting were then used to deduce the nature of the fiber movement, thus determining the distribution of the accelerated points. The accelerated point distribution under different parameters was obtained. Gauss distribution was found to suitably describe the accelerated point distribution curve under different parameters used in this study. The pressure bar to some degree imparts a significant control of floating fibers within the drafting zone. The relationship between the sliver unevenness and the accelerated point variance (CV) was also discussed.

Penciptaan Karya Film Animasi “Sky Land” Dengan Teknik Dua Dimensi

Animasi bertemakan fantasi tidak hanya dalam bentuk cerita, namun dari segi karakter visual dan environment. Dari segi karakter ada yang berupa sesosok anak kecil hingga dewasa sampai dengan berbagai jenis monster, serta tak jarang terdapat karakter dan environment yang tidak dijumpai dimuka bumi.Animasi pendek “Sky Land” menceritakan Sena seorang gadis kecil pengumpul kayu yang menemukan sebuah kayu ajaib di sebuah hutan yang mampu mengeluarkan benda-benda ajaib, hingga membawanya ke negeri fantasi di atas awan dan membawanya berpetualang.Animasi pendek “Sky Land” ingin lebih memperlihatkan sense of art didalamnya, maka animasi ini diproduksi menggunakan teknik animasi dua dimensi (2D) digital hand drawing, yaitu menggambar frame by frame secara langsung dengan komputer baik karakter maupun background. Kata kunci: Fantasi, Animasi 2D, Sky Land Abstract Fantasy-themed animations are not only in story form, but in terms of visual and environmental characters. In terms of character there is a form of a small child to adult up to various types of monsters, and not infrequently there are characters and environments that are not encountered in the earth.The short animation of "Sky Land" tells Sena a small girl who collects a magical wood in a forest capable of removing magical objects, bringing her to a fantasy land on a cloud and taking her on an adventure.Short animation "Sky Land" wants to show more sense of art in it, then this animation is produced using two dimensional animation technique (2D) digital hand drawing, that is drawing frame by frame directly with computer both character and background.

The Parametric Design of Pulley Based on AutoCAD

This design mainly takes pulley as the research object. First collect the data of pulley, bring round the body of the reference point, design the User DCL dialog, then preparing Auto Lisp diver. The procedure involves drawing frame, title bar, shape, tolerance and coarse and so on the surface, generated by the input parameter , you can take the implementation of parts of the system
