The twin-tube shock absorber was studied and the relevant factors of thermal equilibrium were simulated. The dynamic model of the shock absorber was constructed and simulation curves of force-displacement and force-velocity were output. The experiment of the twin-tube shock absorber was carried out,and the results were compared with the modeling resultss. Further,the vibration energy regeneration model was established,and the bench simulation study was carried out. The results showed that the energy regeneration model not only absorbed shock energy but also converted vibration energy into electricity energy. 相似文献

烧结机台车篦条材质选择及生产技术 总被引:4,自引:0,他引:4
通过分析认为,铸铁的耐熔性是决定篦条使用寿命的关键因素。笔者主持研制生产的新型稀土镁变质复合石墨铸铁篦条的平均使用寿命长达1年零6个月,篦条消耗量降至0.067kg t矿。适合于小型烧结机特别是无铺底料工艺条件下的烧结机使用。 相似文献
