摘要
为确定沙滩清洁车履带架上橡胶减振器最优的设计参数。首先利用三维建模软件Pro/E,建立橡胶减振器三维模型;然后运用ANSYS有限元分析法,对橡胶减振器在实际工作压力下进行静力学分析,求解出其的最大变形量、最大等效应力以及最大主应变峰值,并根据最大主应变峰值下的疲劳寿命预测公式预测其疲劳寿命;最后运用田口法对橡胶减振器进行优化设计。结果表明,橡胶内径值对减振器变形量影响最大,得出最优的设计尺寸,为橡胶减振器设计提供理论依据。
To make the design parameters of rubber vibration isolator on the crawler frame of beach-cleaner optimalliest,3D modeling software Pro/E is used to set up the 3D rubber vibration isolator model.A nd then the finite element analysis method is used to analyzed the statics under the pressure of practical work ,the maximum deformation, equivalent stress and maximum principal strain of the rubber vibration isolator is concluded. The fatigue life is predicted with the fatigue life prediction formula for the peak value of maximum principal strain.Finally, the taguchi method is used to optimize the rubber vibration isolator. It is concluded that the inner values of rubber is the maximal influence of its deformation.At the same time find out the optimal size and provide theoretical basis foidesiguing the rubber vibratioh isolator.
