Abstract: The application of simulation technology in the teaching of automobile maintenance training effectively solves the practical problems of insufficient teaching equipment and insufficient teaching funds. At the same time, it satisfies the students' perception of space, makes the theoretical teaching and practical training organically connect, stimulate students' interest in learning skills and achieve good teaching results.However, software simulation cannot replace the actual operation of automobile maintenance, in actual teaching, the two must be combined organically to give full play to the best effect of simulation teaching.
