This paper will analyze the mechanical performance of the wheel and design a test-bed to test the performance of the lunar rover's wheel. Firstly, the mechanical characters of the soil are separated to press-sinkage character and shear character based on Bekker's theory, and common press-sinkage and shear models are introduced and the theory of Lankine passive earth pressure is also introduced. These basic theories are helpful to construct model.

Actually our operation also is not much more abysmal, the report is diagnosed in earlier analysis inside, we basically are mixed to their target user the investigation that target market had development and analysis, to this client, what they need is not much visit capacity, have effect user in great quantities however, such mechanical industry user group mix in bourg for the most part out-of-the-way and a mountainous area, the capacity of user computer operation of these areas is very small, they understand the channel of the product to pass Baidu besides oneself basically is to let close friends seek relevant data for them outside the search, these information chose which kind of promotion means to provide clue for us, first selection is Baidu contest price for certain, it is the advertisement of mechanical industry website next.

其实我们的操作也不是多深不可测，在初期的分析诊断报告里面，我们主要对他们的目标用户和目标市场进行了深入的调查和分析，对于这个客户来说，他们需要的不是大量的访问量，而是大量的有效用户，这样的机械行业用户群大部分都在村镇和偏远山区，这些地区的用户电脑操作能力都很低，他们了解产品的渠道除了自己通过百度搜索外主要是让亲朋好友来替他们找相关的资料，这些信息就为我们选择哪一种推广方式提供了线索，首选肯定是百度竞价，然后是机械行业网站的广告。
