    第一次上何老师的课

    从选导师到后来的本科毕业设计一直到现在,我跟何老师打交道挺久了,但上他的课还是头一回。中午我们从实验室出发,第一次坐上了何老师的车。何老师给我们上的是工程决策论,内容跟以前的系统工程差不多,不过我好像全部都忘了,而且当时就没怎么学懂,希望这次能顺利把这门课消灭掉。因为我还有更重要的事情要做,我要研究大风车。
     
    找软件找了好久,我觉得能找到的几率很小,再等下去也不是个办法。我要自己编程算啦!!!目前的困难是我不知道风车的转速随风速的变化情况,这似乎与控制有关,不是我的研究范围,希望我的同门同学刚哥早点把速度追踪弄出来。还有一些工况也跟控制密切相关,例如启动、关机、空转和偏航,这些工况对疲劳寿命影响很大,但我自己根本没法算。。。哎,天呐!!!好麻烦。
     
    另外还要考虑波浪载荷,最后做疲劳分析。何老师建议我用abaqus,一个我不了解的软件,看来学软件是逃不掉的了。他还提到桩土耦合,p-y曲线之类的,一下子把我拉回了本科的毕设当中。估计最后我会用等效桩去做,abaqus毕竟不是sacs 5.2,不一定有桩土耦合分析的功能。哎,这个还是先放一放吧,现在要集中精力算风车载荷。
     
    呵呵,跟何老师聊天后觉得挺有启发的,似乎每次都是这样。这大概就是导师的威力吧。
     
    在没有新资料的情况下,我唯有先假设一个转速,把算风车载荷的程序写出来。。。。等有了转速随风速变化情况后再修改。明天开始用matlab编程。
     
    一个困难重重的研究正在进行中。。。
