style="text-indent:25px">球形封頭的性能與特點(diǎn)分析：1、從受力情況看：球形封頭的兩向應(yīng)力相等，而且在相同的P和D條件下，球形封頭上的應(yīng)力*為筒體上的周向應(yīng)力的一半；橢圓形封頭經(jīng)線曲率變化平滑連續(xù)，故應(yīng)力分布比較均勻，對于標(biāo)準(zhǔn)橢圓形封頭ab2，在相同的P和D條件下，封頭較大的薄膜應(yīng)力數(shù)值上與圓筒中的周向應(yīng)力相等。故橢圓形封頭的受力狀況*次于半球形封頭，而比其它封頭好；2、從制造難易程度看：橢圓形封頭的深度比半球形封頭淺的多，較易制造；3、從制造所使用的材料多少來看：從理論上講，在一些條件均相同之下，標(biāo)準(zhǔn)橢圓形封頭壁厚大約比半球形封頭厚一倍，而與圓筒的壁厚相近。故球形封頭比橢圓形封頭更節(jié)約材料。4、從結(jié)構(gòu)上看：球形封頭為半個(gè)球殼。5、球形封頭因具有受力均勻、應(yīng)力較小的等優(yōu)點(diǎn)被普遍用于壓力較高、直徑較大的高壓容器和特殊需要的場合；橢圓形封頭經(jīng)線曲率變化平滑連續(xù)，易于沖壓成型，是目前應(yīng)用較多的封頭。不銹鋼封頭就算經(jīng)過長期的使用也不會(huì)輕易出現(xiàn)銹蝕的現(xiàn)象。</p><div
