</div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">物料料性的标定是EDEM离散元仿真最为核心的一部分。</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;">所说</span>的物料料性的标定，<span style="color: black;">指的是</span>在进行EDEM模拟仿真前，必须先对该工况下所<span style="color: black;">运用</span>的物料进行<span style="color: black;">海量</span>实验，从中获取<span style="color: black;">关联</span>的数据，例如物料的堆密度、粒径分布、安息角、滑动角等实验参数。<span style="color: black;">经过</span>计算机模拟<span style="color: black;">理学</span>实验过程，并<span style="color: black;">按照</span>仿真结果进行EDEM中仿真程序相应参数的<span style="color: black;">调节</span>，使得仿真结果与实验数据一致。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">EDEM中的校准工具Calibration Kid，<span style="color: black;">供给</span>了丰富的校准方式，能够匹配现实<span style="color: black;">理学</span>实验校准过程及实验工具，无需再进行<span style="color: black;">另一</span>的建模。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">下面<span style="color: black;">重点</span>介绍<a style="color: black;">深圳市德颐姆科技有限<span style="color: black;">机构</span></a>五种物料的标定实验：</span></p><strong style="color: blue;"><span style="color: black;">堆密度实验</span></strong><strong style="color: blue;"><span style="color: black;">粒径分布实验</span></strong><strong style="color: blue;"><span style="color: black;">剪切实验</span></strong><strong style="color: blue;"><span style="color: black;">安息角实验</span></strong><strong style="color: blue;"><span style="color: black;">滑动角实验</span></strong>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">其中，堆密度、粒径分布以及剪切实验用于在EDEM中设定基本<span style="color: black;">理学</span>特性，获取这些特性参数后再进一步进行物料标定实验。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">标定实验<span style="color: black;">重点</span><span style="color: black;">指的是</span>安息角实验和滑动角实验，其对在EDEM中接触参数的输入有<span style="color: black;">指点</span><span style="color: black;">功效</span>，<span style="color: black;">亦</span>是<span style="color: black;">保证</span>EDEM仿真准确性和<span style="color: black;">靠谱</span>性的必要环节。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">注：<span style="color: black;">因为</span>物料粒径分布对物料校准实验的结果存在<span style="color: black;">很强</span>影响，<span style="color: black;">意见</span>在<span style="color: black;">选择</span>物料时尽可能做到“随机、均匀”等<span style="color: black;">需求</span>。</span></p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">堆密度实验</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">该实验<span style="color: black;">重点</span><span style="color: black;">经过</span><span style="color: black;">必定</span>体积V的容器来装满物料，<span style="color: black;">经过</span><span style="color: black;">叫作</span>重工具得到容器内物料的总质量m。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">运用ρ=m/V计算公式，<span style="color: black;">就可</span>得到物料堆密度。反复多次实验求得平均值。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">注：EDEM离散元仿真软件中所运用的密度为物料的真密度，即需要<span style="color: black;">经过</span>物料堆积实验进行标定获取。</span></p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">粒径分布实验</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">物料经过振动筛分机进行筛分后，对各层物料进行<span style="color: black;">叫作</span>重并绘制成物料粒径分布实验数据。如图所示，该物料的中位径为7.5mm，最大物料粒径为100mm<span style="color: black;">上下</span>。从而有利于在EDEM软件中设定颗粒的真实粒径分布。</span></p>
