摘　　要：针对测量发动机缸筒变形的传统方法成本较高的问题,提出了在测量过程中采用模拟缸盖代替真实缸盖的方法,并选用6种不同的缸盖,在某6缸发动机上进行了试验研究。研究结果表明,对于该6缸发动机,在测量其缸筒变形量时,可采用40mm钢板挖孔的模拟缸盖(第3种缸盖)代替真实缸盖。As cost of traditional method of measuring cylinder deformation is high,it is presented that the simulating cylinder head is substituted for the real cylinder head,and 6 different cylinder heads are selected to test on a 6-cylinder engine.It is shown that,for a 6-cylinder engine,the simulating cylinder head of a 40 mm-thick steel plate with holes (the 3rd cylinder head)can be substituted for the real cylinder on measuring cylinder deformation.
