Abstract


The tire uniformity test machine belongs to test equipment on-line. It is a key test system of tire manufacturing. The product accords with the direction of national development in this field, and it is also the industrialization item being emphasizing study by our country. Nowadays, the machine relies on import completely. The study of this item is to change the situation not able to produce the uniformity test machine and to drive the development of our national tire manufacturing.The tire uniformity test machine is both a mechanical and an electric product. This paper emphasizes on the study of arithmetic resolution and controlling system of the uniformity and brings forward an effective test method. In order to develop the precision of the test machine, induct least square and extend its application. Deeply study the uniformity test principle. Apply the mechanics principle to analyze the uniformity test procedure and educe the uniformity test method. In the way of data-collection, analyze the method of connection and signal pick-up, ensure the data are available. With regard to the data processing, apply low-pass filter and band-pass filter to pick up the frequency signal according with the require of uniformity test. And then apply Fourier arithmetic to analyze the frequency spectrum to get each harmonious wave of the force vibration. The communication between the home computer and PLC adopts Ethernet communication mode which is popular used now. Since it needs to communicate in real time, adopt multithreading technique in the software programming and take available methods to assure the synchronization of the thread. Meanwhile, this paper also develops the home computer software. In the process of the development, apply more popular technique, such as encapsulation, multithreading, Ethernet communication and so on. Adopt SQL SERVER RDBMS to save and manage data. The software is of mightiness function and runs steady and reliable.
