Due to the limit of the static strength theory designed in tracked vehicle

it can’t reflect the dynamic loads suffered by the main part

so it is difficulty to analysis the reliability and remained life prediction

in some degree it affect the performance.The collaborative simulation based on interfaces is used in tracked vehicle and with the flow chart the methodology analysis the reliability and life prediction properly of all ingredient under the dynamic loads suffered in different task profile

and then prove its’ feasibility with an example of planetary frame.The research on collaborative simulation based on interfaces used in tracked vehicle not only solve the technical problem which caused by complex task profile but also join the engineer tightly

it is significant in practice.
