封面 摘 要 近年来，随着城市规模的不断扩大，高层建筑和住宅小区不断增多，房地产业迎来了一轮强劲的发展势头，随之而来的是水泥产业的巨大的市场份额。可是水泥的运输却成为水泥产业发展的羁绊。 2009年初以来实施的一揽子刺激经济计划明显见到效果, 尤其是4万亿元投资计划的逐步落实，使经济结构出现了以原材料行业为先导的发展模式。这种结构性增长模式促使水泥行业率先复苏，迎来了新一轮的需求高峰。1～11月份，水泥市场逐渐见旺，产量以较高的速度增长，全国水泥产量14.93亿吨，同比增长19%，增幅比去年同期提高了13.3个百分点。预计09年全年产量约16.4亿吨，比08年约增加2.4亿吨，同比增长约为17%。 该散装水泥运输车的设计内容包括：底盘的选取，罐体的设计，卸料系统的设计和各重要部件的强度校核。所选用的底盘是中国重汽的ZZ3257N3847C型。 关键词：混凝土搅拌车 整车布置 罐体 ABSTRACT In recent years, with the continuous expansion of city scale, high-rise buildings and the growing residential area, the real estate industry ushered in a strong growth momentum, followed by the cement industry, a huge market share. However, the transport of cement has become the fetters of cement industry. Since early 2009, the implementation of significant economic stimulus package to see the results trillion yuan in particular, the gradual implementation of investment plans, so that the economic structure appeared to raw materials industry-led development model. This structural growth model to promote recovery in the cement industry take the lead, ushered in a new round of peak demand. 1-11 months, the cement market has gradually changed for the better, yield a higher rate, the national cement output of 1.493 billion tons, up 19%, an increase over last year increased by 13.3 percentage points. Forecast 2009 annual output of about 1.64 billion tons, compared with an increase of about 240 million tons in 2008, up about 17%. But the traditional cement transport, loading and unloading means spend a lot of manpower and material resources and low efficiency, but also thanks to packaging, shipping, generated a lot of white pollution or the cost of upgrading. It can not meet the requirements of modern society, a cost-effective nor environmentally friendly concept. If the use of concrete mixer truck transportation to the cement dust emissions in the atmosphere can be reduced by 0.5%, transport one million tons of cement per bag of paper can sa
