【摘要】 针对目前雪橇车由于设计与结构的原因而存在行进中产生较大颠簸和冲击的问题,提出一种双自由度雪橇独立悬架系统,在该悬架系统中包括一个阻尼移动副和一个转动副,通过球销副与减震器配合可以把路面作用于雪橇板上的垂直反力、侧向反力传递到整个雪橇车身,以保证雪橇平稳行驶并提高舒适性.采用ADAMS软件对雪橇机构悬架系统在不同路况下产生的振幅进行仿真,并用Solidworks三维建模软件对雪橇板应力分布进行了仿真分析,结果表明该减震悬架系统能够大大降低雪橇在复杂路况下产生的震动.更多还原

【Abstract】 Aiming at the problems of large turbulence and impact in the current sled vehicles due to design and structure,a dual-degree-of-freedom sled independent suspension system is proposed. The suspension system includes a damping moving pair and a rotating pair.The vertical reaction force and the side reaction force of the road surface acting on the ski board can be transmitted through the cooperation of the ball pin pair and the shock absorber and the torque transmission caused by these reaction forces. To the entire sled body to ensure smooth running of the sled and improve comfort. The ADAMS software is used to simulate and analyze the amplitude and stress distribution of the sled board when the sled mechanism suspension system is running under different road conditions. The three-dimensinoal modeling software Solidworks is used to simulate and analyze the stress distribution of the sled board. The results show that the damping suspension system can greatly reduce the sled movement.Vibration generated under complicated road conditions.更多还原
