A new static calculation method of gap produced by the dimensional tolerance, form tolerance and position tolerance was developed based on the traditional tolerance formula. The vane dumper widely used in battle tanks is used as an example. Comparison of the computed value based on the model with the experimental data shows that the mathematical model is validated. With the model, the contribution of each tolerance to the damping force variation can be worked out. It is seen that the damping force variation can be greatly decreased only by reducing some key tolerances.
