In the last years,several vehicles — with different problems — have been equipped with
active absorber systems to attenuate the transmission of the engine vibrations into the
vehicle cabin.As mentioned earlier,the control algorithms have to be chosen with regard to
the particular problem of the considered vehicle.ContiTech has equipped a test vehicle with
an AVC system with inertia-mass shaker attached on the transmission cross-member.Figure
8 shows the location of the system components on the transmission cross-member in the test
vehicle.
The control algorithm is implemented on a rapid prototyping unit,the dSPACE
MicroAutoBox.The electronic hardware consists of an amplifier and filter unit that contains
the power amplifier and the anti-aliasing filter for the sensor signal,and the electronic
control unit.A remote control on/off switch is used to turn the control algorithm on and off
during vehicle tests (Kowalczyk et al.,2006).

过去几年里,几款车型(面临不同的减震要求,出现震动问题的原因各异),均配备了相应的主动减震系统,用来减轻发动机传递到驾驶室内的震动.我们说过,针对各车型因不同原因引起的震动问题,需要采用不同的控制算法.ContiTech(康迪科技公司,或者叫 大陆科技 or 欧陆科技)在试验车上安装了avc系统,并在变速箱横梁上安装了惯性抖动器.图8标明了各系统组件在变速箱横梁上的相应位置.
控制算法(固件,软件部分)依靠一个快速成形组件来实现,这里采用dSPACE公司的 MicroAutoBox(一个硬件产品).用到的电子设备(硬件部分)则包括一个“放大--滤波器”组件和电子控制组件——前者包含功率放大器和处理传感器信号的抗混叠滤波器.整个试验过程利用(非接触式的)遥控技术来决定 控制算法 的运行或停止.
