EDEM在重型工业设备上的运用和分析
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">为了满足市场<span style="color: black;">需要</span>并保持竞争力，重型设备制造商需要<span style="color: black;">持续</span><span style="color: black;">加强</span>其设备的性能，效率和<span style="color: black;">靠谱</span>性，<span style="color: black;">同期</span>还要在<span style="color: black;">保证</span><span style="color: black;">制品</span>创新的<span style="color: black;">同期</span>快速交付<span style="color: black;">制品</span>。 其中，<span style="color: black;">认识</span>散料的特性以及<span style="color: black;">怎样</span>与设备<span style="color: black;">协同</span><span style="color: black;">运用</span>，是<span style="color: black;">保证</span>高性能的关键。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">针对</span>散料预期<span style="color: black;">行径</span>的假设，这<span style="color: black;">便是</span>数值模拟发挥<span style="color: black;">功效</span>的<span style="color: black;">地区</span>。EDEM是一款用于散状物料模拟的高性能软件。它是基于离散元(DEM)技术，用来模拟散料（如煤、开采的矿石、土壤、碎石<span style="color: black;">乃至</span>粉末）的<span style="color: black;">行径</span>，及物料对设备的影响。在相同的<span style="color: black;">要求</span>下对设备进行虚拟测试，比较<span style="color: black;">因为</span>物料<span style="color: black;">行径</span><span style="color: black;">区别</span>而产生的变化，并快速分析<span style="color: black;">区别</span>的设备结构的性能，从而设计出最佳设备的结构。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">EDEM软件广泛地运用于重型工业设备的设计优化。运用EDEM与MBD耦合可以<span style="color: black;">容易</span>地重复执行相同工况，且满足<span style="color: black;">各样</span>极端工况的模拟。<span style="color: black;">经过</span>仿真能够<span style="color: black;">认识</span><span style="color: black;">区别</span>物料对设计性能的影响，观察与分析设备作业时物料的流动<span style="color: black;">状况</span>，预测散料状态，识别堵塞、洒料等问题，获取重型设备工作时的受力和磨损<span style="color: black;">状况</span>，提取用于疲劳<span style="color: black;">评定</span>的数据等其它的有用的信息，从而优化设备性能，<span style="color: black;">加强</span>设备<span style="color: black;">运用</span>寿命。</span></p>
