| Abstract: | The characteristics of fluid flow in hydraulic retarder are studied and a math model is established. The air blasting loss in retarder is also discussed. Based on these,a prototype of hydraulic retarder with new structure for loss reduction is designed and tested on a rig.The results show that the test value of braking torque in retarder is close to that of theoretic design and the new structure has satisfactory effect in reducing air blasting loss. |
