基于LCA/LCC的汽车发动机最佳再制造时间点的确定

为了解决传统发动机再制造生产活动效率较低、耗时耗材多、修复质量难以把握等问题,需要提前预测废旧发动机性能退化状况,在产品报废之前、性能退化之后对其进行再制造。本研究以EA2111.4L新桑塔纳汽车发动机为研究对象,采用产品生命周期评价(LCA)与全生命周期成本(LCC)理论,将发动机生命周期成本和能耗作为影响再制造时间点的两个重要因素,建立生命周期能耗和成本与服役周期的映射函数关系,利用多目标优化方法及遗传算法确定发动机最佳再制造时间点,最终得到EA2111.4L新桑塔纳汽车发动机的最佳再制造时间点为6.42 a。本方法为废旧发动机及相关产品提供了的再制造时间点的量化参考,为汽车产业进一步降低能源消耗、节省成本、减少环境污染提供理论支持。

Establishment and application of service mapping model for proactive remanufacturing impeller

Since the complex impeller structure and the difficult remanufacturing process may easily cause advance remanufacturing or excessive use,an optimized design method of impeller and service mapping model was presented for its proactive remanufacturing with setting up to explore the best remanufacturing time point in this work.Considering a certain model of long distance pipeline compressor impeller with the Basquin equation and the design method of impeller,the mathematical relationship between the changes of structure and life of the impeller was established.And the service mapping model between the structure and life was set up and simulated by ANSYS software.Thus,the service mapping model was applied to feedback the original design for proactive remanufacturing.In this work,the best proactive remanufacturing time point of impeller was analyzed with the service mapping model,and the structural parameter values could be optimized at this time point.Meanwhile,in the results of this simulation,it proves that the impeller under this optimization performance could satisfy the impeller operating demands.Therefore,comparing with the traditional optimization design method,the remanufacturing optimized design based on the service mapping model is feasible in proactive remanufacturing for sustainable development.

Benefit analysis and contribution prediction of engine remanufacturing to cycle economy

The first automobile engine remanufacture company in China, Jinan Fuqiang Power Co, Ltd, was introduced. The engine remanufacturing technological process of this company was described. The benefit statistic of remanufacturing 10 000 Styer engines were analyzed, and the contribution of engine remanufacturing to cycle economy was predicted. The results show that remanufacturing engineering could use the maximal additional values of obsolete engines, and make contributions to materials conservation, capital saving, energy conservation and environment protection. 10 000 engines are supposed to be remanufactured per year, the following benefits would be obtained: reclaiming additional values of RMB3.23 hundred million, saving metallic materials about 7.65 thousand tons, saving energy of 16 million kilowatt-hours, reducing emission of CO₂ about 11.3–15.3 thousand tons, and providing employment for 500 persons. According to the survey and analysis, tremendous benefits will be gained by the year of 2020. For example, reclaiming additional values per year of 1424–2236 hundred million RMB, saving energy per year of 60–90 hundred million kilowatt-hours, reducing emission of CO₂ about 6.67–9.69 million tons. It can be deduced that developing remanufacturing will play an important role in enriching the cycle economy and accelerating the development of national economy.
