做了个草图，难度极大！
今天做了个草图~·gochinway06；） 不规则形~·精度要求真的是奢侈~···昂贵的奢侈！ 怎么是不规则形嗫 考虑过材料之间冷热膨胀系数以及施工温度吗 arion 发表于 2015-1-11 11:32考虑过材料之间冷热膨胀系数以及施工温度吗
你是指制作温度还是安装温度？
膨胀率当然有考虑，只是目前没法确定具体数据 SJ2.0 发表于 2015-1-11 08:54

制作温度、安装温度、工作温度，没有材质的膨胀系数怎么考虑公差 arion 发表于 2015-1-11 13:03
制作温度、安装温度、工作温度，没有材质的膨胀系数怎么考虑公差
其实归根到底就是公差~·这些做机加工没有不考虑的，只是我考虑的是如何获得合适的数据 fissa 发表于 2015-1-11 14:22

这些机加工有多少知道材料的变化？你能得到哪些材料？中缸的开放式水道因为温度的变化，尺寸会如何变化？什么材质，什么牌号？温度应力曲线如何？温度公差曲线如何？ arion 发表于 2015-1-11 15:26

我去拧螺丝``gochinway06；） 要研究的一辈子都研究不完
自己用，可能考虑不了那么多，但必须要考虑的我一定会考虑~
今晚拿台发动机备着，以备万一
其实今晚我确实是买了台发动机~分解了慢慢研究吧~·
好在还是有些资料可查，也会和镶缸套的师傅好好聊聊~
不急着装车，但这事我一定会做的，装车再交作业大家指教
难度确实很大，有许多要考量的~·但，我一定要去做gochinway72；）不简单的~·
