摘　　要：拖拉机动态特性是决定拖拉机适应性、可靠性的主要因素。通过对拖拉机振动特性、轮胎刚度及整机转动惯量的分析计算,求解了某型拖拉机的固有振动频率,并根据固有频率特性设计动态强化试验,进行了整机及部件结构基本可靠性的验证,为拖拉机整机、部件设计及机具选配提供依据,为拖拉机整机及部件基本可靠性验证提供方法。The natural frequency of a tractor is solved by analyzing and calculating the vibration characteristic, tire stiffness and rotational inertia of the tractor. According to the natural frequency characteristic, a dynamic strengthening test is designed, then the reliability of the tractor and parts is verified. Some basis are provided for tractor part design and farm machinery matching, and a method is supplied for basic reliability verification of the tractor and parts.

关 键 词：拖拉机 振动特性 可靠性验证
