Aims Probability design theory is used to provide the theoretical basis for improving the performance index of the leaf absorber. Methods By probabilistic design, find out the direct relationship between the vane damper with the size tolerance and the rated resistance distribution. To determine the main shock absorber size with the size tolerances. Results After improving the design, the working stability of the vane damper has been significantly improved under the premise of basically unchanged manufacturing cost. Conclusion Probability design approach can be structural parameters of the product design and product performance indicators and product yield directly linked. Integrated product design from the perspective of cost performance is an advanced design method.
