Centennial College is working with Horstman Systems that has developed a range of electronically controlled active and semi-active vehicle suspension systems that drastically reduce the shocks occupants experience over uneven terrain. The active suspension technology has been applied to seats for vehicles experiencing high levels of shock such as off-road land vehicles, marine rescue boats in rough seas, and aircraft or helicopters in heavy turbulence and hard landing events. The reduced shock may substantially reduce the incidences of spinal and other physical injuries experienced by the occupant. When mounted in certain vehicles such as boats or aircraft, the seat may experience some use cases that are not commonly encountered by land vehicles. One of these is the freefall, for example in the case of a boat being dropped into the water from a larger vessel, or a helicopter experiencing a hard landing due to engine failure. Horstman has made improvements to the control algorithms using simulation, but the software must be tested and validated in real life using controlled drop tests. The proposed project will involve Centennial College designing and constructing a drop test rig designed to simulate the free fall event for a single seat. A series of drop tests will then be conducted to validate active controller performance and allow for any modifications to control parameters as needed.

百年纪念学院正在与霍斯特曼系统公司合作，该公司开发了一系列电子控制的主动和半主动车辆悬架系统，大大减少了乘客在不平坦地形上所经历的冲击。 主动悬架技术已应用于经受高水平冲击的车辆的座椅，诸如越野陆地车辆、在波涛汹涌的海上的海上救援船以及在严重湍流和硬着陆事件中的飞机或直升机。减少的震动可以显著地减少乘员所经历的脊柱和其他身体损伤的发生率。 当安装在诸如船或飞机的某些车辆中时，座椅可能会经历陆地车辆不常见的一些使用情况。 其中之一是自由落体，例如在船从较大的船只落入水中的情况下，或者直升机由于发动机故障而经历硬着陆。Horstman已经使用仿真对控制算法进行了改进，但是必须使用受控跌落测试在真实的生活中对软件进行测试和验证。拟议的项目将涉及百年学院设计和建造一个旨在模拟单座自由落体事件的跌落试验台。然后将进行一系列跌落试验，以验证主动控制器的性能，并允许根据需要对控制参数进行任何修改。
