经典测力应用-EKM机车重心称重架桥

The Art of Precision – Force transducers, amplifiers, mechanical constructions, software and systems for the quality control of railway vehicles

AST最具竞争力核心体现在与生命息息相关的铁路机车产品质量控制的测量检测系统，全部高精度测力传感器、放大器、变送器、计算机软件及机械结构部件，均由AST设计制造，确保整个系统的高精度及高可靠性。

high-speed trains assume – just because of their mass and size – an unbelievable exactness in dimension and manufacturing processes.

尤其是高铁（高速铁路机车）由于车身体积庞大、车重较大，其制作过程的精度掌控重要性是不言而喻的。

A.S.T. delivers the key for the highest precision: Starting from the single measuring cell, modules and measuring systems up to calibration units there comes the complete precision chain out of one hand.

AST从信号测量传感器、模块、单元计量系统及标定，为用户提供成套检测系统的高精度技术核心部件。

For adjusting a carbody to the tension-free position, the four sensors move upwards to touch the car body and then the software together with the precision lifting gear is controlling the height and displacement of each sensor until the correct force and tension free position is reached. In Shelf production the EKM 305 S system is used. After you have concluded the inside final assembly, the corner load measuring system EKM 305-F is pushed under the car body.The correct corner forces are calculated following the newest standard DIN25043 which incorporates the position of the center gravity. After the car body reaches its tension free position, you can measure the geometric dimensions.

测量机车的受力测量，最为关键的就是没有任何干扰外力的影响。EKM机车测力系统，EKM 305S称重架桥采用4个双路测力传感器及位移检测计算机检测系统，分析承重机车的移动位置及受力状态，尤其是装置偏离的各种侧向外力，以保证高精度准确测量。EKM 305-F再在机车装配后，进行推动力计量检测。每个力点及位置数据汇集到DIN25043分析及累加，并综合重力加速度参数，最终精确给出车辆几何尺寸。

After mounting the bogies to the car body, our RAK402 systems are used to sense each wheel load, axle loads and bogie loads to the rail.

RAK 402检测系统，可直接测量每个车轮载荷、轴载及车轨载荷，用于车身装配后的测量检测。
