1. 研究目的与意义（文献综述）

1.1 researchpurpose

finish the framedesign of vehicles for dismantling end-of-life vehicles.

1.2 researchbackground

the automobileproduction and sales increased rapidly in china's auto industry inrecent years. according to statistics, by the end of 2014, china registeredvehicles reached 155.47 million, an increase of 12.42% compared to 2013. it isexpected that china's car ownership will reach 200 million in 2020. the generalcar service life is 10 to 13 years, and the increase in car ownership led tothe rapid growth in the number of end-of-life cars. scrap car dumping not onlycauses serious land occupation, but also causes air and water pollution,wasting a lot of available resources. therefore, the effective recovery ofscrapped vehicles is necessary, otherwise the environmental and economicproblems caused by it will become more and more serious.

scrapped carscontain many recyclable metals and non-metallic materials, which have a greatvalue. it is also an important part of the national recycling economy. itsrecycling has broad prospects, of which 90% of steel and non-ferrous metals canbe recycled, so as to achieve the purpose of saving energy, materials andcosts. the specification of the scrapped car dismantling can, to some extent,slow down the destruction of the environment during the dismantling of thescrapped cars. scrapped car can save resources, to achieve circular economy andsustainable development after dismantling, classification and recycling,
