| 摘要： | The project's objectives are to model and simulate a heavy tactical wheeled vehicle with gross vehicle weight rating of 66,000 lbs, the Heavy Expanded Mobility Tactical Truck (HEMTT) M1120A4. Matlab will be used to complete a modal analysis of the half-truck model identifying the first 10 natural frequencies with corresponding mode shapes, the response of the cabin with input from the road, and the firing frequency of the selected engine. The analysis will consist of a baseline vehicle weight with a peacetime configuration and conclude with a parametric analysis of increasing the cabin weight, simulating the increased protection of the vehicle. The project goals will be to develop a detailed mathematical model of a heavy tactical wheeled vehicle. The detailed model will be used to complete a modal analysis identifying the fundamental vibration mode shapes and corresponding excitation frequencies which will be used to identify steering column and seat vibration impacts to the Soldier and crew. |
