| 中文摘要 | 电控液压助力转向系统(ECHPS)具有随车速调节的可变助力特性,可改善驾驶员的转向路感.通过对转向器转阀及ECHPS的分析,建立了转向器模型以及分流式ECHPS的模型,采用简化算式对转向器及分流式ECHPS操舵力特性曲线进行了分析.通过改变转阀的预开隙、转阀的坡口半径、转向器扭杆刚度及电磁阀阀芯节流口形状等参数,分析了ECHPS的影响参数.计算结果表明分流式ECHPS操舵力特性主要取决于转向器转阀的结构参数,并且和电磁阀阀芯开口有一定关系.; Electronically controlled hydraulic power steering(ECHPS) improves driver's 'road feel' because it has alterable assistance character.Steering gear model and bypass ECHPS model were built based on the hydraulic principle of the control valve and ECHPS.A simple formula suited the two models was used to analyze the assistance character of steering gear and ECHPS.The bypass ECHPS parameters' affections were analyzed by changing basic gap' width or slot's radius of the control valve,or torsion bar's stiffness of steering gear or both of basic gap' width and slot's radius.The electromagnetic valve' affection was also analyzed by changing the orifice's figure of the spool.The results show that the assistance character of the bypass ECHPS is determined mostly by the control valve of the steering gear,it has relations with the electromagnetic valve else.; 中国博士后科学基金资助项目(20060390457) |
