Analysis of Automobile Transmission Shaft Structural Reliability Considering Safety Factor
Reasonable design and selection of automobile tansmission shaft is very important to ensure the reliability of vehicle power system.Considering the influence of safety factor,the relia-bility mathematical model of the stress limit state of the transmission shaft is established,and the reliability design theory,first order second moment method(FSOM)and Monte-Carlo simulation(MCS)numerical simulation method are combined to calculate the structural reliability and reliability sensitivity of automobile transmission shaft.Taking a certain type of automobile transmission shaft as an example,the reliability of automobile transmission shaft selection under the influence of safety factor is discussed.The most influential factors of automobile transmission shaft reliability are obtained,which provides an important reference value for the subsequent structural selection and steady optimization design of the automobile transmission shaft.
