<h2>一、拉延筋类型</h2>
<ul>
<li><strong>半圆形</strong>：最常见，阻力均匀</li>
<li><strong>矩形</strong>：阻力大，适合厚板</li>
<li><strong>梯形</strong>：可调性好</li>
<li><strong>拉延槛</strong>：用于深拉延件</li>
</ul>
<h2>二、关键参数</h2>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>参数</th>
<th>推荐范围</th>
</tr>
</thead>
<tbody>
<tr>
<td>筋高</td>
<td>4-8mm</td>
</tr>
<tr>
<td>筋宽</td>
<td>10-20mm</td>
</tr>
<tr>
<td>圆角半径</td>
<td>R3-R8</td>
</tr>
<tr>
<td>筋间距</td>
<td>30-80mm</td>
</tr>
</tbody>
</table>
<h2>三、设计流程</h2>
<p dir="auto">压料面确定 → AutoForm阻力计算 → 布置筋条 → CAE迭代 → 试模优化</p>
