2008年8月20日,国家发改委对外公布包括一汽在内14家企业将在全国率先试点汽车零部件再制造,实现废旧汽车零部件的再生制造,再造出的产品技术性能和安全质量同样能达到原产品的标准。同时还确定了试点的五大基本原则:一是暂不允许再制造企业从报废汽车拆解企业收购“五大总成”进行再制造,其他零部件按照《报废汽车回收管理办法》相关规定执行;二是再制造产品原则上不得低于同类原产品新件的质量保修期;三是零部件再制造企业不得回收或再制造未获得授权的其他企业产品;四是再制造产品应进入汽车生产企业售后服务系统进行流通,不得直接向社会零售市场销售;五是再制造企业应获得可再制造旧件的原生产企业的商标使用权。 相似文献

汽车零部件再制造产业现绿色商机 总被引:1,自引:0,他引:1
当前,全球每年至少有2600万辆汽车报废,如果将它们首尾相连,大概可以绕地球赤道1.5圈.为了避免生活在汽车垃圾堆上的可能,全球都在进行报废的汽车零部件回收再制造工程.在中国,这一事项也迎来"破冰"--今年全国"两会"期间,全国人大代表、长安汽车董事长尹家绪就汽车再制造提出了相关建议和议案. 相似文献

Limited by techniques, the process of remanufacturing exists masses of uncertainties which have a great impact on the remanufactured parts quality, how to achieve a higher quality of mechanical products by using limited remanufactured parts precision, has become one of the key issues of remanufacturing industry. Firstly, with a target to reduce uncertainties and improve the quality of automatic products, a method of tolerance grading allocation for remanufactured parts is proposed based on the uncertainty analysis of the remanufacturing assembly. The dimensional tolerances of the mechanical parts are divided into positive and negative two groups. We use selective assembly method to reduce assembling deviation. Then, the method is proven by mathematical formulas that the remanufactured parts variance can be expanded to two times, and the tolerances can be liberalized 40 % through tolerance grading allocation method. It is also the theoretical basis for improving the reuse radio and quantitatively describing the tolerance liberalization in this paper. Finally, feasibility research on this method is studied from the angle of cost–benefit. Furthermore, a tolerance grading allocation example of remanufactured engine piston assembly in a power corporation shows the validity and practicality of the proposed method. 相似文献

Disassembly sequencing using genetic algorithm 总被引:3,自引:2,他引:1

At the end-of-life (EOL) of a product, there are several options available for its processing including reuse, remanufacturing, recycling and disposing. In almost all cases, a certain level of disassembly may be necessary. Thus, finding an optimal (or near optimal) disassembly sequence is crucial to increasing the efficiency of the process. Disassembly operations are labor intensive, can be costly, have unique characteristics and cannot be considered as the reverse of assembly operations. Since the complexity of determining the best disassembly sequence increases with increase in the number of parts of the product, it is extremely crucial that an efficient methodology for disassembly sequencing be developed. In this paper, we present a genetic algorithm for disassembly sequencing of EOL products. A case example is considered to demonstrate the functionality of the algorithm. 相似文献

China has once again dropped its import tariff rate on motor vehicles starting from July 1.The tariff rate cut from 28% to 25%,which is applicable to the import of all types of passenger vehicles.At the same time,the average tariff rate on automobile parts went down from 25% to 10%.This is the last adjustment of the tariff on complete vehicles in implementation of the commitments China made on its entry into the World Trade Organization.This adjustment came only six months after the last one… 相似文献
