This paper discusses the performance and working principle of pressure feedback controlled hydraulic taming and drawing equipment and puts forward that with the shock pressure changing reasonably according to the resistance , the shock energy and frequency can change independently and steplessly 摘要对压力回馈控制液压夯拔装置的性能和机理进行了分析，提出了针对立柱阻力适时调节系统的冲击压力，可实现冲击能和冲击频率的独立无级调节。
Further more , the fuzzy controller realizes the control of the workpiece feed speed and the welding heat through the fuzzy control algorithm according to the current , voltage parameter and the displacement parameter feed back . the hardware and software design is described in detail in this paper 工件送进系统由电液伺服阀实现精确控制，焊接热量由大功率可控硅实现无级调节，焊接电流及电压参数的采集采用霍尔传感器，实现了闭环控制。
Keeping the self - adjusting of damping behavior when the controllability of semi - active damping is disable , or saving the unnecessary energy when the continuous modulation of damping is not needed , the composite structure for self - shifting between passive and semi - active structure is presented 摘要当磁流变减振器半主动功能失效时，为保持其阻尼性能仍具一定的自调节性或实际路况不需无级调节时，节省不必要的能耗，提出用于车辆半主动悬挂系统的被动与半主动功能自动切换的复合结构磁流变减振器。
The article analyses the principle of such a system first . combined with the valve plate simulation and experiment result , the concrete machine structure and control system can be decided . in the article , the important part - valve fork is particularly analyzed ; at last , two concrete application in industrialization is referred 本文首先详细分析了此新型气量无级调节系统的工作原理，结合阀片工况模拟和实验室试验结果，确定了可调回流气阀的具体机构和气量调节控制系统，特别对其关键部件?压叉进行了失效分析和改造，并使用了塑料压爪，最后介绍了两个气量无级调节系统的工业化实例。
This machine adopts the advanced technology of plc computer programming , hmi operation interface , variable frequency speed regulating . with the high degree automation , the machine has the feature of reliable working and easy operating . it has the ability to receive paper , winder , seal , send paper , label at the same time 本机采用先进的plc电脑程式控制，人机界面操作，速度无级调节，性能稳定，自动化程度高，操作简单，对于进纸、封边、卷角、封口、出纸、贴标签同时进行，适用于标准型纸手帕，迷你型纸手帕和平整规则的四方形物体的塑胶薄膜包装。
Our factory increase a set of intensifier with non - grade - adjustable rating speed to form the intensive air drying , the wet material mixed with hot air fully by screw feeder in the intensifier and material surface is crashed into fine granules and moving to the outlet as well as drying , under rapid rotating hitting and pushing . in the long run , the materials get a further even drying in the dryer pulled by the wind force and those wet and weighty granules the wind force can not pull continue to be crashed , dried until they are pulled by the wind force into the dryer 我厂强化型气流干燥是在基本型上增加一套转速可以无级调节的强化器组成，湿物料通过螺旋加料器进入强化器后和热气流充分混合，在飞速旋转的击刀击碎和推进下，物料被破碎成细颗粒，在干燥同时向出口移动，最后在风力吸引下进入干燥管，进一步均匀干燥，风力无法吸引的湿重颗粒继续被击碎、干燥、直至能被风吸起进入干燥管。
Lifting and lowering of the pringting arm of this machine is vertical , therefore , in case of half - tone printing , presence of screen wire and consistency of aberration are improved ; in case of spot printing , stability and uniformity of inking are enhanced ; fine adjustment and lock of the worktable is independent of each other , so positioning error caused by lock of the worktable can be controlled ; height and pressure of the printing blade and ink - returning blade can be stepless - regulated separately , which improver printing quality and service life of half - tone ; printing travel and half - tone fixing mechanism can be fast adjusted , which is suitable for printing area with different size 本机印刷大臂升降为垂直升隆式，网线版印刷时网线表现率为色差一致性得到提高，实地版印刷的施墨稳定性及均匀性得以加强；工作台微调与锁紧独立，因工作台锁紧而带来的定位误差得以控制；印刷刀、回墨刀高度及压力均可单独无级调节，提高了印刷质量和网版的使用寿命，印刷行程和网版固定机构大小可快速调节，方便不同规格的印刷面积。
The electric power harmonic comprehensive control system with low cast and high security is applied in this article . it adopts that sourced compensation links with non - sourced compensation herewhich the former is realized by high frequency pwm control technology and the latter is carried out by crystal switch formed by non - flow and over - voltage . it can realize stepless modulation with imaginary power , mightiness compensation of harmonic and negative electricity , and circuitry consumption debasing are achieved 提出采用有源补偿与无源补偿相结合的电力谐波综合治理技术及装置，无源部分采用无涌流和过电压的晶闸管控制电容器技术实现，有源部分采用高频pwm控制技术实现，成本低、可靠性高、可实现无功功率的无级调节、强力补偿谐波电流和负序电流，降低线路损耗。
