One example for the application\r\nfor the project results is the reduction of vertical vibrations of an electric wheelchair\r\n(AVC – Active Vibration Control). In this case, the aim is to reduce the whole body\r\nvibrations during the ride by the exchange of passive damping elements through controllable\r\nsemi-active ones. For the experimental analysis in time and frequency domain, the\r\nwheelchair has been equipped with accelerometers. Furthermore, a test stand that enables\r\nthe quasi-harmonic stimulation in vertical direction (0 Hz – 30Hz, ±5mm) on a wheel\r\nthrough the use of an eccentric has been constructed and realized. To create realistic and\r\nreproducible measurement a DIN-certified dummy (DIN 45676) has been created to emulate\r\nthe mechanic input impedance of the human body. The evaluation of the vibrations is\r\ncalculated in compliance with the ISO 2631-1 (human vibration). For the mechatronic design,\r\na multi-body system of the wheelchair has been created in SIMPACK, while the determination\r\nof stiffness and dampening of the wheels has been determined experimentally.\r\nIn this contribution, results of measurements of the wheelchair on the test stand and the\r\nsimulated calculations in frequency domain will be presented. At first, the model will be\r\nused to determine the parameters of the optimized spring-damper-element in various driving\r\nand operating conditions. In a second step, passive damping elements will be replaced\r\nby semi-active ones. The regulation of the controllable damper will happen in line with a\r\nco-simulation between SIMPACK and MATLAB/Simulink. This enables the gauging of\r\nthe efficiency of the model's various control algorithms connected to the semi-active\r\ndampers; the findings can later be used for the realization on the real wheelchair. Parallel\r\nto the simulation calculations, the real wheelchair will be enlarged by the integration of\r\ncontrollable electro-rheologic damping elements and the installation of a mechatronic system\r\nto improve the driving comfort in the next stage of the project."}],"alternative_title":["An approach to improve the Ride Comfort using Semi-Active Dampers"]}
