In this paper,firstly,a gear paramet-ric model with base pitch error is established based on Pro/E secondary development,and given a method and idea to generate error model,there-fore,it is guaranteed that continuous body gear dy-namics is simulating successfully.the gear model is menshed based on APDL command flow language mesh by using ANSYS’s pre processing func-tion,and a meshing control method is given in or-der to ensure high accuracy and to calculate time fast.The explicit dynamics software LS DYNA is introduced for the dynamics calculations,thereby,it is achieved that gear bending stress and contact stress during engagement impact is calculated accu-rately.
