With the increase of the number of people's household cars, people pay more attention to the maintenance of car
failures, and people's safety awareness is constantly improving, so safe travel has become a basic and important
requirement for people. In road traffic, the probability of traffic accidents is getting bigger and bigger, and most of
the accidents are caused by mechanical failure of automobiles, except for the unskilled driving skills of drivers in
the internship period. Cars can not only improve people's travel conditions, but also bring people various troubles.
Without paying attention to the daily inspection and maintenance of cars, many kinds of mechanical failures will
occur in cars. Fault diagnosis is a process of diagnosing the running state and abnormal situation of equipment
and determining the general location of faults. This paper analyzes the causes of automobile mechanical failure,
studies the key technologies of automobile fault diagnosis and maintenance based on mechanical deformation, and
puts forward preventive measures for automobile mechanical failure.
