| Abstract: | Based on establishing the steel-rubber(S-R) model for the axle box's linking rod of truck, consider- ing its structural features and the fact of high stiffness ratio between the steel and rubber, provides a simplified rigid body-rubber(R-R) model by means of the principle of rigid body displacement. The computing results with R-R model show that it has a better precision, and the benifit in quantity-grade is gained on data treat- ment, computer storage and computing time. |
