摘　　要：在某型号3缸汽油发动机前期开发阶段,根据发动机爆震引起燃烧室共振并传播给缸体的现象,通过有限元分析,使用GT-power软件与Abaqus/Standard求解器对缸体进行了频域下的频率响应计算,并对计算结果进行了分析,以确定合适的爆震传感器位置。In the early development stage of a 3-cylinder gasoline engine of a certain model,according to the phenomenon of combustion chamber resonance caused by engine knock and propagating to the cylinder block,the frequency response of the cylinder block in the frequency domain was calculated by using GT-power software and Abaqus/Standard solver through finite element analysis.The calculation results were analyzed to determine the appropriate knock sensor location.
