摘　　要：为了提高空气净化器在流通过程中的安全性,根据空气净化器的规格和防护要求,以瓦楞纸板为材料设计缓冲衬垫,选择60 cm的高度对缓冲单元进行了面、棱和角3种方式的跌落仿真,根据仿真结果,面跌落产生的极限应力2.033 MPa,低于缓冲材料的极限应力2.38 MPa,棱、角跌落缓冲衬垫的极限应力分别为3.882 MPa和4.847 MPa,均超过了衬垫材料的极限应力,但跌落过程中的冲击加速度分别为56.0 g、15.3 g和27.4 g,小于空气净化器的脆值80 g。因此,所设计的缓冲单元在跌落过程中对内装物起到了保护作用,针对应力集中部位进行结构优化,提高了缓冲单元的缓冲效果。In order to improve the safety of the air purifier in the circulation process,according to the specifications and protection requirements of the air purifier,the corrugated paperboard was used as the material to design the cushion pad.The height of 60 cm was selected to simulate the drop of the buffer unit in three ways:face,edge and corner.According to the simulation results,the ultimate stress produced by the surface drop was 2.033 MPa,which was lower than the ultimate stress of 2.38 MPa of the buffer material.The ultimate stresses of the edge and corner drop cushion pads were 3.882 MPa and 4.847 MPa respectively,both of which are higher than the ultimate stress of the cushion material.However,the impact acceleration during the drop process was 56.0 g,15.3 g and 27.4 g,respectively,all of which were less than the brittleness value of 80 g of the air purifier.Therefore,the designed buffer unit can protect the contents during the falling process.The structure optimization of the stress concentration area was carried out to improve the buffer effect of the buffer unit.
