摘要
基于缓冲套一般工作原理,提出一种多孔缓冲套结构的设计。液压缸在运行过程中通过不断改变缓冲套总节流面积,使得速度平稳下降,从而起到缓冲作用。并建立了数学模型,用AMESIM软件对缓冲套在液压缸中的应用进行了仿真,得出了缓冲腔的压力曲线,活塞的位移和速度曲线,通过设置不同的管道模型直径,对其参数进行了优化设计,仿真结果证明了这种缓冲套的缓冲效果好和实用性强。该缓冲套可以根据实际工况需要改变节流孔的大小位置和个数,实行对缓冲套装置的多样化设计,以保证生产实际的需要。
A design of porous buffer was proposed based on work principle of buffer sets.The speed of the hydraulic cylinder have been declined steadily by changing the total throttle area of the buffer sets constantly for buffering.A mathematical model of the buffer was built and was simulated in the applying of the buffer to the hydraulic cylinder by AMESIM software to obtain pressure curves for buffer cavity,piston displacement and velocity curves,which parameters were optimized by setting different diameter pipeline model.The results confirm the buffer sets with better buffering effect and high practicality.Therefore,the buffering sets could change size,location and numbers of the throttle orifices according to the actual condi-tions to diversify the design for the buffer sets,thus the actual requirement for production is ensured.
