中文摘要:基于先导溢流阀原理设计了一种内置电磁阀式阻尼连续可调减振器,对可调阻尼力进行了理论分析,在Simulink中建立其力学仿真模型;结合减振器试验标准设计可调减振器的试验方案,利用INSTRON-8800型单通道伺服激振台架对可调减振器样件进行试验。试验结果表明,减振器的复原阻尼力调节范围为0~3.72kN,压缩阻尼力调节范围为0~1.01kN;并且与仿真结果之间的误差未超过20%,证实了减振器模型的正确性和减振器结构的可行性。通过试验获得的阻尼力与电流关系可为半主动悬架控制器的匹配开发提供数据支撑,为减振器设计提供参考。

Abstract:Due to the requirements of suspension layout space and vehicle performance, a damped continuously adjustable shock absorber with built in solenoid valve was designed based on principle of pilot valve. The structure of the adjustable shock absorber and the formation principle of adjustable damping force were introducted. And then the working strokes of the adjustable shock absorber was modeled mathematically based on the theory of fluid mechanics and the abstract model of shock absorber working stroke. The simulation model was also established by Matlab/Simulink and different characteristics of the adjustable shock absorber at different currents were obtained. Combining with the national standard of the passive shock absorber, the experiment proposal of the novel damped continuously adjustable shock absorber was designed. At the same time, the adjustable shock absorber test was carried out on the INSTRON-8800 CNC hydraulic servo single-channel excitation platform. From the test results, it can be seen that the adjustment range of rebound damping force was 0~3.72kN, the adjustment range of compression damping force was 0~1.01kN. The error of the test and simulation results did not exceed 10% as the current was in the range of 0.2~1.4A and it did not exceed 20% as the current was more than 1.4A, which confirmed the accuracy of the damper model and feasibility of the damped continuously adjustable shock absorber. The relationships between the damping force and the currents were acquired which can provide data support for the matching development of its semi-active suspension controller and provide the reference for the design of the damped continuously adjustable shock.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
