Research on Modal and Harmonic Response of Engine Connecting Rods Made of Different Materials
This article takes a certain engine connecting rod as the research object,and conducts finite element modal and harmonic response research on connecting rods made of three different materials,40 Cr,45 steel,and QT40-10,respectively,and obtains the natural frequencies of three different materials of connecting rods,areas prone to resonance failure,and frequencies that external excitation should avoid.The research results indicate that:the natural frequency of QT40-10 is lower than that of 40 Cr and 45 steel,and connecting rods made of 40 Cr medium carbon alloy steel should avoid higher external excitation frequencies and have the smallest amplitude.
