Many force feedback virtual reality simulators use linear actuators. However, available linear actuators sufferfrom a significant cogging response during operation. This is a significant complication since the forcefeedback response should feel analogous to the forces experienced in reality. In the proposed research project, acogging-free linear actuator will be developed. This will be achieved by redesigning the magnet packing andthe use of ferromagnetic material in the motor to obtain a uniform magnetic field rather than developing anadditional means of control.The development of the new clogging-free actuator technology will underpin Iris' ambition to expand salesbeyond its current niche market of force-feedback flight yokes into Helicopter Cyclics and motion platformsused for helicopter simulation which require high precision force-feedback response. In addition, the projectwill directly serve the West Coast Wave Initiative's development of a sustainable energy technology solution byproviding cost-efficient simulators for the development of Wave Energy Converters which must provide forcefeedback that mimics the reactions of the actual system.

许多力反馈虚拟现实模拟器使用线性致动器。然而，现有的线性致动器在操作期间遭受显著的齿槽效应响应。这是一个重大的复杂性，因为力反馈反应应该感觉类似于现实中所经历的力。在本研究计画中，将开发无振动之直线驱动器。这将通过重新设计磁体包装和在电机中使用铁磁材料来获得均匀的磁场而不是开发额外的控制手段来实现。新的无阻塞致动器技术的开发将支持Iris的雄心，即将销售从其目前的力反馈飞行轭利基市场扩展到直升机循环和用于直升机模拟的运动平台，这些平台需要高精度的力。反馈响应此外，该项目直接服务于西海岸波浪倡议的可持续能源技术解决方案的开发，为波浪能转换器的开发提供具有成本效益的模拟器，波浪能转换器必须提供模仿实际系统反应的力反馈。
