Test Rig Design to Validate the Performance of a Vehicle Seat with Active Shock Attenuation Active Shock Attenuation

百年纪念学院与霍斯特曼系统公司合作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受到的冲击。主动悬架技术已应用于越野陆地车辆、海上救援船、飞机或直升机等遭受高强度冲击的车辆的座椅上，如在剧烈湍流和硬着陆事件中。减少的电击可能会大大减少乘员脊柱和其他身体伤害的发生率。当安装在某些车辆（如船只或飞机）上时，座椅可能会遇到一些陆地车辆不常见的用例。其中一种是自由落体，例如，一艘船从一艘较大的船只落入水中，或者一架直升机由于发动机故障而经历硬着陆。Horstman已经通过模拟对控制算法进行了改进，但该软件必须在现实生活中通过控制跌落测试进行测试和验证。拟议的项目将涉及百年纪念学院设计和建造一个旨在模拟单座自由落体事件的跌落测试平台。随后将进行一系列跌落测试，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。

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.
