利用ADAMS建立某型步兵战车传动系统当量模型,研究双质量飞轮主要参数对发动机扭振衰减效果的影响,得到了双质量飞轮第二、第一飞轮转动惯量比的取值范围以及扭转刚度和阻尼的取值原则,以发动机激励衰减最优为目标,同时优化双质量飞轮3个参数,得到最佳的转动惯量比值为0.612;提出设计周向长弧形弹簧式双质量飞轮的具体方法和步骤,设计出弹性机构不同布置的2种双质量飞轮,并通过仿真计算其减振效果。结果表明:弹簧组布置在减震盘两侧的长弧形弹簧式双质量飞轮的减振效果较好。
The ADAMS equivalent model of infantry fighting vehicle was established to study the influence of the main parameters of the dual mass flywheel on the torsional vibration attenuation of the engine. The range of the moment of inertia ratio of the second and the first flywheel with double mass flywheel and the torsion stiffness and The principle of damping is taken as the objective, and the optimization of the two parameters of the mass flywheel is optimized. The best ratio of moment of inertia is 0.612. The specific methods and steps of designing the long arc-shaped spring type double mass flywheel are proposed, Two kinds of double mass flywheels with different elastic structures are designed and their damping effects are calculated through simulation. The results show that the long arcuate spring type double mass flywheel with spring group arranged on both sides of the shock absorption plate has better vibration damping effect.
