提出了一种新型的能量收集液压互连悬架（EH-HIS），并对其进行了建模、建造和试验，以提高车辆的乘坐舒适性和道路操纵性能，同时将传统上浪费的振动能量转化为可用的电能。开发了一个子模块原型来验证分析模型，并进行了测试，以研究EH-HIS的阻尼特性和能量收集能力。研究比较了传统悬架、液压互连悬架（HIS）、液压电磁能量收集减振器（HESA）和EH-HIS的整车动力学响应和能量收集性能。台架试验结果表明，EH-HIS的阻尼系数在3608 ~ 9913 Ns/m之间。在2 Hz频率和20 mm振幅的激励下，子模块的平均收获功率达到82 W，而配备EH-HIS的全尺寸SUV在D级道路上以60 km/h和80 km/h的行驶速度分别获得215 W和525 W的平均功率。此外，与其他悬架系统相比，配备EH-HIS的车辆在崎岖地形上具有更好的乘坐舒适性和令人满意的操纵稳定性。分析还表明，EH-HIS表现出60%和11%的抗侧倾和抗俯仰性能比传统的悬架在紧急转向和制动演习。
A novel energy-harvesting hydraulically interconnected suspension (EH-HIS) is proposed, modeled, built and tested in this paper to enhance riding comfort and road handling performances for vehicles while converting the vibration energy traditionally wasted into usable electricity. A sub-module prototype has been developed to validate the analytical model and tested to study the damping characteristics and energy harvesting capability of the EH-HIS. The studies are performed to compare the dynamic responses and energy harvesting performance of the full-vehicle equipped with the traditional suspension, hydraulically interconnected suspension (HIS), hydro-electromagnetic energy-harvesting shock absorber (HESA) and the proposed EH-HIS, respectively. Bench test results show that the damping coefficient of the EH-HIS ranges from 3608 to 9913 Ns/m. The average harvested power of the sub-module reaches 82 W at the excitation of 2 Hz frequency and 20 mm amplitude, while the full-size SUV equipped with the EH-HIS can obtain 215 W and 525 W average power on D-class road with a driving velocity of 60 km/h and 80 km/h, respectively. Moreover, the vehicle equipped with EH-HIS has better riding comfort on rough terrains and satisfying handling stability compared with other suspension systems. The analysis also indicates that EH-HIS exhibit 60% and 11% improvements in the anti-rolling and anti-pitching performances over the traditional suspension during emergency steering and braking maneuvers.
