使用SW6―2011计算压力容器开孔补强的几个问题0 引言为满足工艺或结构需要，在压力容器设计中开孔是必不可少的。

容器开孔接管后会引起开孔或接管部位的应力集中，再加上接管上会有各种外载荷所产生的应力及热应力，以及容器材料和制造缺陷等各种因素的综合作用，使得开孔和接管附近就成为压力容器的薄弱部位。

虽然标准和规范对设计和计算都作了较为详细的规定，但在使用SW6-2011过程设备强度计算软件计算开孔补强时需要注意对标准规范中有关定义的理解和把握，灵活运用软件，必要时对有关数据进行调整，才能得到正确的结论，保证设备的安全可靠性。

1 补强方法及适用范围1.1 计算时应注意的问题在使用SW6-2011计算开孔补强之前要先判断接管的直径和壁厚是否满足GB150.3-2011中6.1.3不另行补强的最大开孔直径[1]的要求，满足要求的可以不进行计算，没有进行判断直接输入数据的，生成计算书会显示满足不另行补强的最大开孔直径的要求，不予进行计算。

还需要注意的是单个孔开孔补强计算合格，然而该孔的有效补强区B=2d范围内还有其他开孔，形成孔桥的，则应按孔桥处理。

在计算两相邻开孔中心的间距或者任意两孔中心的间距时对曲面间距应按弧长计算，按照弦长或中心线垂直距离计算是不正确的。

1.2 补强计算方法及适用范围的理解SW6-2011补强计算方法给出四种：等面积补强法、另一补强方法、分析方法和压力面积法。

计算软件中的等面积补强法是指单个开孔的等面积法，联合补强法是指多个开孔的等面积法。

等面积法是开孔补强计算方法中最广泛应用的计算方法，该法是以补偿开孔局部截面的一次拉伸强度作为补强准则的，是以无限大平板上开有小圆孔时孔边的应力集中作为理论基础的，即仅考虑容器壳体中存在的拉伸薄膜应力，对开孔边缘的二次应力的安定性问题是通过限制开孔形状，长短径之比和开孔范围（开孔率）间接考虑的[2]，使用该法应考虑开孔是否满足GB150.3-2011中6.1.1的规定。

使用SW6—2011计算压力容器开孔补强的几个问题作者：司文华来源：《山东工业技术》2013年第10期【摘要】开孔补强是压力容器设计中必不可少的一部分，在压力容器结构设计前需要使用SW6-2011过程设备强度计算软件进行强度计算。

为保证计算的准确性，必须透彻理解SW6-2011软件计算的理论基础，但在实际工作中，一些设计者常常会忽视标准规范中的某些说明或者对计算理论的理解不够透彻而导致取值错误，直接影响了设备的安全可靠性。

本文列举了几个在日常工作中经常遇到的在使用SW6-2011计算压力容器开孔补强时需要注意的问题及通常的处理办法，提醒设计者在设计工作中引起足够重视。
