以对非制动工况发热特性的进一步优化为前提,对原液压调速软制动器液压回路进行改进。基于Fluent软件,对改进前后的液压调速软制动器液压回路在非制动工况下的低发热特性进行研究比较,结合发热量的理论计算,证实了在非制动工况下液压调速软制动器新增的插装式电磁换向阀所在回路为近似零阻尼回路,该回路具有降低系统运行发热的优点。 Based on the further optimization of the heating characteristics of non-braking conditions, the hydraulic circuit of the soft-timing hydraulic brake was improved. Based on the Fluent software, the low heat generation characteristics of the hydraulic circuit of the hydraulic speed-regulating soft brake before and after the improvement are studied and compared under the non-braking condition. Combining with the theoretical calculation of calorific value, it is proved that the hydraulic speed- The new circuit of the plug-in electromagnetic reversing valve of the brake is an approximate zero-damping circuit, which has the advantage of reducing the heating of the system.
