不知啥时在论坛上经常出现的“计算”这个词非常频繁。我理解的计算其实不难,难的是如何找到计算所需要的条件,应该是很主要。比如这个轴流式止回阀的,如果分析一下看是否有道理。管道的内径横截面积所受到的力与管道压力的关系。也就等于止回阀所受到的力。 上述为山寨版的理解,计算就不会,看是不是这意思,供参考:lol

我也是做轴流式止回阀的,你算这个是为了设计弹簧还是要干嘛用?如果是全关状态下,那这个力就像一楼所说的,压力乘个轴向投影面积就是了,但一打开由于有背压,所以力应该是压差乘面积,而难就难在这个压差不知道!

您是兰州理工大学的学生呀? 张教授的学生吗? 主要是设计弹簧用的,用fluent分析,但是不怎么会,您有资料可以参考吗?
