本文对非公路机械用无阀主动振动阻尼系统和阀控主动振动阻尼系统的能量消耗进行了比较。今天，只有被动振荡阻尼系统是越野车系列生产的对象。这些系统的优点是不需要额外的初级能源用于阻尼。但缺点是成本高，对运行参数无自适应能力。阀门控制线性执行器用于主动阻尼的最新发展不得不面临几个问题，即当今实施的控制阀的动态过低以及额外的高能量需求。这些缺点可以通过使用无阀线性执行器来实现工作功能和主动阻尼来避免。事实上，节流损失被忽略，能量回收是可能的。测量和仿真结果表明，无阀线性执行器可以获得合适的阻尼质量。因此，本文将给出控制器设计的几个方面。因此，使用了一个简单的加速度传感器和标准的控制硬件。主要部分将描述能量模型，其中特别精确的泵损失模型已经开发。详细比较了两种主动阻尼系统的能耗。
This paper presents a comparison of the energetic consumption of a valveless and a valve controlled active oscillation damping system for off-road machinery. Today only passive oscillation damping systems are subject to off-road machine series production. These systems offer the advantage of no additional primary energy use for damping. However, the disadvantages are the high costs and no adaptation possibility to the operating parameters. The recent developments where valve controlled linear actuators have been used for active damping had to face several problems with too low dynamics of today’s implemented control valves and the high additional energy need. These disadvantages can be avoided by using valveless linear actuators for working functions and for active damping. In fact, throttling losses are omitted and, energy recovery is possible. It will be shown based on measurement and simulation results that a suitable damping quality can be achieved with valveless linear actuators. Therefore, some aspects of the controller design will be given. Hereby, a simple acceleration sensor and standard control hardware are used. The main part will describe the energetic modelling, whereby especially precise pump loss models have been developed. The energy consumption of both systems performing active damping is compared in detail.
