Therefore , all of the above have improved the drive reliability and performance - cost ratio , etc . furthermore , the operation discipline of this new drive is illustrated in detail and the topology and its parameters calculation are also presented . finally , a 300w pattern is manufactured to simulate and test the new drive 论文详细分析了系统工作原理，进行了拓扑和参数设计，并完成一套300w样机的制作，通过相应的仿真和实验测试，验证了系统的可行性，特别适用于频繁减速或刹车制动的电动车辆。
Three kinds of mechanical brake including air brake , hydraulic pressure brake and air - hydraulic pressure brake are given according to the second demonstrative maglev train which is amending . based on the actual conditions of the sample maglev train and technical indicator , we chose air - hydraulic pressure brake , and have confirmed that it is feasible by the experiment 针对正在改型的第二辆工程化样车,提出了空气制动、液压制动、空气-液压制动三种机械制动方案,根据样车的实际情况以及制动的技术指标,确定了空气-液压的制动方案,并且通过试验确定了其可行性。
This system has a lot of the prominent characteristics such as simple structure , and good efficiency , especially adapting to the large , middle power machine equipments that have the big qualities , periodicity , in the short time , constantly accelerating and applying the brake . it is very remarkable in energy - saving 二次调节静液传动系统具有许多显著的优点，比如：较为简单的结构，并可得到较高的效率，特别适用于那些负载质量较大、具有周期性、在短时内需不断加速和制动的大中功率场合(如车辆系统和升降系统) ，其节能效果十分显著。
Firstly , in this thesis the dynamic model of the low - speed maglev train is analyzed . on the analysis of the principle of electric brake and mechanical brake the structure of electric - mechanical brake control system is set up . the concept of brake task programming and electric - mechanical brake controller is put forward 首先,本文通过分析低速磁浮列车的动力学模型,研究了低速磁浮列车电制动和机械制动的原理,分析和构建了电-机械联合制动控制系统的结构,提出了制动任务规划器和电-机械联合制动控制器的概念。
The inertia brake is attributed to pure mechanical product , which has the function of both resisting gale and braking , and is used safely and reliably , so it is popular very much with the customers of port , metallurgy , mine , lifting and transporting vocation and so on 惯性制动器是根据惯性制动原理设计的,融制动器、联轴节以及二者相互转换功能于一体的新型装置。惯性制动器属纯机械产品,兼有防风与制动的功能,安全可靠,因而倍受港口、冶金、矿山、起重运输等行业用户的欢迎。
Abstract : the main points of using and maintenance of isuzu nhr vehicle are described in this paper . the concrete contents include following points : checking of the oil level , braking fluid level and the tension of fan belt ; maintenance of the air cleaner and battery ; adjustment of the valve clearance and parking brake 文摘:阐述了五十铃nhr货车的使用与维护要点，即润滑油油位的检查;风扇皮带挠度的检查;空气滤清器的维护;气门间隙的调整;蓄电池的维护;驻车制动的调整及制动液液位的检查等。
It is shown in the simulation that sliding mode control can guarantee the stability and robustness while vehicle is braking even if abs operates at the instability region of the adhesion coefficient and wheel slip curve or the surface condition changes , which is better than the pid control and nonlinear pid control 仿真结果显示，即使在附着系数和滑移率关系曲线的不稳定区域，或是路面状况发生变化，滑模控制也能保证制动的稳定性和鲁棒性，其控制效果优于pid和非线性pid控制效果。
