Vibration Analysis of Track with Rubber Bushing in Tubular

摘要: 不同于原来的金属铰链履带,现代履带多采用销耳挂胶结构,履带的结构和特性均发生了变化。针对现代履带结构变化,应用梁的弯曲振动理论建立了销耳挂胶履带动力学模型。考虑到挂胶层的作用,将履带视为一段拉力下的梁模型,推导了含有履带梁弯曲刚度项的固有频率计算公式。并对一段履带进行了试验验证,对比了理论计算数据与试验数据。结果表明,与传统基于弦的横向振动模型相比,基于梁弯曲振动理论建立的模型能更准确地描述履带振动特性。Abstract: Different from the traditional metal hinge track, a new structure with rubber bushing in tubular has been used in modern track, which means the dynamic property of modern track is also different. A dynamic model of track with rubber bushing in tubular was established based on the transverse vibration theory of beam in consideration of the new structure in modern track. The natural frequency formula that contains flexural rigidity was worked out on condition that treated the track as a beam with tension. A vibration experiment of a track is carried out, and according to the experiment results, the track model based on beam transverse vibration is more accurate in describing the track vibration property than traditional models based on string with transverse vibration.
