Abstract

If an object is transported on a mobile platform, all accelerations of the mobile platform affect the object. This is of course undesirable, since accelerations can move or even damage the object. Stewart-platforms are mostly used for simulation, where the platform generates accelerations that increase the simulation's quality. Vice versa, it's possible to use a Stewart-platform mounted on a mobile platform to compensate the unwanted accelerations by generating a tilt. The necessary movement of the platform is calculated by a washout-filter. Applications of this combination include the transport of liquids in open boxes and medical transports, where the patients must not be affected by any acceleration.

基于stewart平台的移动机器人主动加速度补偿
如果物体在移动平台上运输,移动平台的所有加速度都会影响物体。这当然是不可取的,因为加速度可以移动甚至损坏对象。stewart平台主要用于仿真,其中平台生成加速以提高仿真质量。反之亦然,也可以使用安装在移动平台上的stewart平台,通过产生倾斜来补偿不必要的加速度。平台的必要移动由冲洗过滤器计算。这种组合的应用包括在开箱中运输液体和医疗运输,其中患者不得受到任何加速度的影响。
