本文主要就动稳定度试验时所采用的试验温度、车辙板厚度、荷载压力、车辙板压实度等进行试验与评价。 - That is , through analysis of the principle on flow control and " hydraulic transistor " , design and calculation of flow control characteristic as well as main parts in valve inner chamber , a piloted reducing valve will be installed between main valve and pilot valve . after a pressure - difference compensating reducing valve was added in the non - pressure compensating piloted reducing valve of the flow control valve in vlalvistor valve , the calculation on control characteristic emulation and load characteristic emulation has been carried out . the result of the calculation shows that after pressure compensating reducing valve was added , the linearity of the control characteristics has been greatly improved thus eliminating influence upon outlet flow by load pressure - change of the hydraulic system and improving performance characteristics of the hydraulic component
文章还在对瑞典valvistor阀的插装比例阀研究的基础上，提出了一种新的流量控制原理，即：通过对流量控制和“液压晶体管”原理的分析、流量控制特性及阀内腔主要结构件的设计计算，在主阀和导阀之间增设先导减压阀，并进一步对valvistor阀的流量控制阀之无压力补偿先导减压阀、加入压差补偿减压阀后的控制特性进行了仿真计算和负载特性仿真计算，结果表明：增设压力补偿先导增压阀后，其控制特性曲线变得非常线性，从而消除了液压系统负载压力变化对主阀输出流量的影响。 - This paper analyses the type , function and characteristics of usual proportional control valves and raises a new modificative version in the light of their drawback . that is , basing on the principle of flow amplification and electrical feedback and throughout calculation and analysis on flow closed loop control and pressure flow combination . , determination of the minimum controlled pressure difference as well as flow controlling range and structure of main valve and research of the dynamic and static characteristic , the paper puts forward control principle of " flow - load pressure change - displacement revision " and pressure / flow double closed loop , and further expounds that using a proportional controller and a electric mechanical transducer can separately serve the control function of pressure or flow as well as flow pressure combination
本论文分析了目前常用比例阀的类型、功能、特性，并针对其不足提出新的改进方案，即：以流量放大，电反馈两个原理为基础，通过对流量闭环控制及压力流量复合的计算分析、确定上最小控制压差及流量控制范围，确定主阀结构、功能特性研究等，提出了“流量? ?负载压力变化? ?位移修正”的控制原理和压力流量双闭环控制原理，并进一步论述了利用一个比例控制器和一个“电?机械转换器”就可完成独立的压力或流量控制功能以及流量压力复合控制功能。 - The controlled object hyvp ( hydraulic pressure vibration platform ) has the property of big loading pressure and rating power , so it need considerable transmitted and control power , it also has the property of high - level math model , and narrow frequency width in closed - loop , and bad stability . this thesis is based on the hpvs in the “ tiema project ”
被控对象(液压振动台)具有负载压力和额定功率相当大的特点,因此要求传输和控制的功率要相当可观;而且它还具有数学模型阶数高、闭环频带宽度窄、稳定性差等特点。
