2009年度工作总结

研发中心 郑涛 工号2606

 

一、工作内容：

1.本年度主要完成了两项工作：

1.1船舶主动力装置的建模与仿真，以某型舰为实例，建立船舶柴油机、调速器、轴系、水力测功器、船体的数学模型；和同事共同完成液力偶合器、调距桨的建模；进行船机桨联合调试与仿真。

         1.2针对某型登陆舰，建立空载柴油机起动模型；针对空车、接排、航行三种工况进行仿真，探索起动参数对起动过程的影响，研究柴油机转速波动情况对性能的影响，改进其控制策略。

 

2.解决的技术问题：

         2.1接排过程中转速下降过低，在接排信号发出后传递到各系统的延迟时间内，提高目标转速，这样实际接排后转速下降的幅值就相对少了。

2.2实际柴油机转速波动比较大，通过设置Butterworth滤波器过滤频率过高的转速信号，通过设置PID控制器中的微分参数来镇定波形，加强系统的稳定性。

         2.3研究不同的起动空气压力、起动成功转速、起动油量、控制规律、实际控制周期对柴油机起动过程的影响，并探索得到一组最佳的柴油机起动设置参数。

         2.4针对16缸柴油机运转时发生的随机停缸现象，根据不同的误差范围加入分段PID控制，加快系统的响应，提高系统稳定性。

 

3.团队合作情况：

         和其他仿真项目组成员合作愉快，及时地对发现的问题进行沟通和解决，不仅是在工作上，在生活上也互相帮助。

 

4.学术论文：

         “柴油机起动过程的建模与仿真”

 

二、集体活动：

1.参观沪东船厂***的系泊实验；

2.参加交通建设工会预演；

3.参加团委组织的庆中秋苏州一日游。

 

三、展望与规划：

1.在09年工作的基础上，进一步对船舶主动力装置仿真模型进行整理，使其更加精简有效，并完善其通用性，协助仿真实验室的后期建设；

2.希望能够对船舶综合平台管理与控制进行学习和研究；

3.希望工作一年来积累的工作经验能够更好地为来年的工作服务，提高自身的主观能动性，进一步改善工作方法和效率。

 

 

先说两件和标题无关的事情

Any chance of success seemed to vanish in a puff of smoke.

So I had to study hard while doing well at my job.

Some days when I was sleeping I dreamed that I was taking exams.

You knew how many times I was thinking and constructing my future and how much I wished through my endeavor I could return to sjtu for my further study.

When you were on your way to your next dream, you could not have a chance to stop, not to mention giving up.

So sometimes it seemed boring and tedious.

Every day I was doing the same job and preparing for the same target.

To certain extend I even lost interest in movies, which used to be my favorite.

 

A proportion of my colleagues tended to look for a better way of making a living.

The limited wage space and the potential rules pushed us into the rush of taking deliberate action.

These explained why every two or three years our company had to recruit about 20 to 40 new employees.

I was looking forward to foreseeing the fate of this kind of state enterprise.

But I was also worrying that how could our company survive in the fierce market after my boss`s retirement.

A few months before it was said that our company would be recombined into China Shipping, but to our disappointment it came out no result.

 

 

These days in R&&D Centre almost everybody was familiar and crazy with a game called sanguosha, which was developed by yoka games.

Once came the off duty time, we got together at the meeting room and began to play this game.

The chaos of the scene shocked our director.

You could find our solidarity and cohesion here.

 

Just as my dear friend fish said, we could gain knowledge if we exchanged our minds with elder ones.

Since I took office I became more and more interested in the social issues, especially those most related and closed to our life, which I took little notice when I was at college.

When you put an eye on these issues, you would see any kind of social system has its weakness, some of which were hatred by most people, but you still had no ideas to change.

That was because there existed power behind power, profits behind profits, nepotism behind nepotism, officeholders behind officeholders, money behind money, restriction behind restriction and helplessness behind helplessness.

The complicated and sophisticated society had its reason.

During our lunch time we blue collars were always complaining the shortcoming of the social mechanism, talking about our ambition. (yying)

 

I was writing this diary purely for practicing my English writing.

This was the end of July.

How time flies!

I wished next month I would take a vacation and go home for a short rest.
