一个展示直线振动筛筛板上单质点运动情况的仿真实验(中文2600字,英文2300字)
1 简介
    振动筛分是矿物加工领域的一个复杂过程,它受振动情况、筛机的技术参数和物料的性质影响。筛分过程的效率直接影响物料在筛板上的运动状态。物料穿透概率和筛机的效率是很重要的影响因素。因此,研究运动理论和物料的性质具有重要意义,是选择合理的运动学参数,确保有效筛分的重要过程。
筛分实验是筛分理论的基础。传统的实验方法有难以比较结果、容易被外界因素影响和难以取得精确数值的缺点,而仿真实验技术则有实验费用低、没有场地、时间以及实验次数限制,能够对复杂过程进行仿真等优点。仿真技术现在被广泛用于军事、医药和工业领域的研究。

A virtual experiment showing single particle motion on a linearly vibrating screen-deck
1 Introduction
    Vibration screening is a complicated process used in the mineral processing area that is affected by the vibration and other technical parameters of the screen and by the processed material's properties. The mo¬tion of the material on the screen deck has a direct relation to the quality of the screening process. Fac-tors such as the penetration probability of the parti¬cles and the productivity of the apparatus are important. So investigating the theory of motion and the properties of the screened materials is of great sig¬nificance for choosing reasonable kinematic parame¬ters that ensure an effective screening process.
The sieving experiment forms the foundation of screening theory. The traditional experimental meth¬ods have the disadvantages of being complex to oper¬ate, being easily influenced by outside conditions and being difficult to carry out accurately in small scale. Virtual experimental technology, on the other hand, has the advantages of low cost, of having no limits in the field related to the available time and number of tests and of affording the simulation of complex processes. Virtual techniques have been widely ap¬plied in studies within military, medical and industrial fields.
