Job Description

Main duties and responsibilitiesDuring three different projects, the candidates will be expected to build a good understanding of the group’s activity, the organization, the controlling environment. The rotation program offers a unique chance to the candidate to start building his/her network in the Group. The successful applicant will spend:v Six months in Chinav Six months with the internal audit team in Asiav Six months in one of our Asian or African subsidiaries(the order of the projects may change) The time spent in China and with the subsidiary in Asia/Africa will be focused on specific challenging projects. These projects will be related to controlling, risk management, accounting, IT, consolidation or operational issues. During the internal audit project, the candidates will be integrated to the regional team and participate to some audits in Asia (including financial, operational and information systems reviews). At the end of the induction period, they will either stay in China to contribute to the growth of our business, or join another of our subsidiaries, preferably in Asia (Singapore, South East Asia,…) or Africa. Reporting LineThe successful applicants will be coached throughout that period, and their performance will be regularly reviewed by:v A project manager in the country of the project v Asia Internal Audit Manager throughout the Induction Program, as coordinator of the project.

挖机油液监测系统的双光路光纤传感器结构设计。上海二手挖掘机红外点状D型激光器发出的激光通过自聚焦光纤传感器转换成平行光入射到污染油液池进行调制，调制后的激光信号再输出到光电转换电路进行转换。
    CX55B型挖掘机的油液监测系统是利用激光照射被测油液，由于被污染的油液对光具有散射和吸收作用，因此在已知入射光强度及衰减后的出射光强后，就可以求得入射光通过被测油液的相对衰减，而相对衰减的大小反映油液的污染程度。系统一般采用单通道测量法进行出射光的采集，由于使用年久后，光源激励不稳定以及测量环境的复杂多变导致入射光强度变化，从而造成测量不准。针对存在的问题，提出改进后的设计。
1 双光路光纤传感器测量方法
    在原有光路的基础上，再增加一条光路。设，n为人射光强，通过分光比为1：1的Y形耦合器，将入射光一分为二，一路进入测量光路，一路进入参考光路，经过对称光电转换部件后输出的电压分别是P和P2，则根据Beel—Lambert吸收定律可得． Pl=／oKl e l (1)
P2=Iog2e 2 (2)式中 K。、 ——测量光路、上海二手挖掘机参考光路的光电转换系数，在系统设计完后，是一个常量；t1、t2——衰减系数；Z——测量光程，设为相等。式(1)除以式(2)得S=Pl／P2=(Kl／K2)e l 2¨ (3)由式(3)可以得出，K 以及z都不随油液污染度的改变而改变，传感器输出的信号Is仅与t．、t：有关，从而消除了光强、油液颜色等外界环境因素的影响。

3 结语
本文通过设计计算与分析，确定了活齿减速油冷式电动滚筒的结构形式以及零部件结构尺寸。可以看出，由于变速轴承同轴输入输出，且结构紧凑、体积较小，因此满足了电动滚筒的整体结构形式要求。另外，电动滚筒是一种将电动机和减速器同时置于滚筒体内部的驱动装置，在现有技术条件下，由于电动机已达到了其极限尺寸，只能从尽可能减小减速装置的体积方面寻求答案，因此可以说变速轴承的自身结构正是电动滚筒所需要的。本文来源：上海二手挖掘机。
