国内轮胎企业将面临“内忧外困”，形势不容乐观

近年，我国汽车工业高速发展，带动了下游轮胎行业的投资热潮，我国具有良好的投资环境和巨大的市场前景，不仅国内轮胎企业纷纷拟建、扩建轮胎产能，同时极大地吸引了如法国的米其林和美国的固特异、日本的普利司通和意大利的倍耐力等世界跨国轮胎制造商到中国投资建厂，使2006年我国轮胎出口呈大幅增长态势。

特保结束轮胎再赴美

三年轮胎特保期结束,已经在特保期间开始华丽转身的中国轮胎企业再度扬帆出征美国市场。当然,贸易壁垒依旧还在。对此,中国企业要从长远考虑。近年来中国经济的飞速发展刺激了汽车、轮胎产业的迅速崛起。2002-2012年,中国轮胎产量保持年均15％以上的增速,出口量保持年均40％以上的增长速度。中国轮胎在全球市场份额中比重逐渐提高,在一定程度上是受全球制造业重心由欧美向新兴经济体转移带动。欧美轮胎制造商更多侧重生产超高性能轮胎、旅行车轮胎和冬季轮胎等高附加值的轮胎,以加大进口低利润轮胎满足国内需求     

回顾经济危机下各企业应对之策

2008年下半年经济危机爆发以来,其影响可谓空前之大,无论国外还是国内市场都是一片萧条。2009年下半年以来,我国经济形势开始企稳向好,大部分企业开始止跌为盈,危机的狼烟即将散去。危机之前我们因为订单繁忙无暇他顾,危机之中我们因为订单缩水忙于防冬,现在处于危机之后我们还会忙于复苏市场,然而这场危机留给我们很多东西值得思考,值得总结。

Composite indices applied to vibration data in rolling tires to detect bead area damage

The primary objective of this research was to identify an online indicator of tire bead area separation for use in tire durability testing. The dynamics of tires with asymmetric bead area damage and the transmission of vibrations to an axle housing were studied. Experimental results from online data collected on a 67-in diameter roadwheel and a 120-in diameter roadwheel are presented. Statistical measures, trends in frequency content and transient wavelet maps, and composite damage indices were all evaluated as online damage detection features. Trends in statistical measures and frequency content were both indicative of damage progression, but were also sensitive to changes in test conditions. Wavelet maps were indicative of damage progression and showed potential for locating damage circumferentially on a tire. Wavelet analysis of data from both roadwheels indicated that damage increased the amount of higher frequency content in the response signals measured at the spindle arm and axle housing. The increase in broadband content was thought to come from transient vibrations generated when the damaged bead area passed through the contact patch. Composite damage indices that combined frequency and spatial data provided very clear indicators of potential damage initiation events, even predicting the number of ruptures, by drawing out the relevant information in the signals from the ambient vibration. The most effective composite indices multiplied several data signals such that only when all data signals indicated a change would the composite indices also indicate that damage had occurred.

Model predictive control helps to regulate slow processes--robust barrel temperature control

Slow temperature control is a challenging control problem. The problem becomes even more challenging when multiple zones are involved, such as in barrel temperature control for extruders. Often, strict closed-loop performance requirements (such as fast startup with no overshoot and maintaining tight temperature control during production) are given for such applications. When characteristics of the system are examined, it becomes clear that a commonly used proportional plus integral plus derivative (PID) controller cannot meet such performance specifications for this kind of system. The system either will overshoot or not maintain the temperature within the specified range during the production run. In order to achieve the required performance, a control strategy that utilizes techniques such as model predictive control, autotuning, and multiple parameter PID is formulated. This control strategy proves to be very effective in achieving the desired specifications, and is very robust.
