摘要

采用二维有限元方法研究了载荷、销轴与销孔间隙、摩擦因数的变化对拖曳三角板销孔最大接触应力的影响,并将有限元分析结果与几种公式计算结果进行了比较。当销轴与销孔的间隙ΔR=0时,可以采用平均挤压应力公式校核拖曳三角板的挤压强度;当销轴与销孔的间隙与销轴半径的比值λ≥0.02时,为了降低有限元分析成本,在没有更加精确的计算公式时,可以采用赫兹应力公式校核拖曳三角板承压能力,赫兹公式计算结果与有限元分析结果的误差小于10%。

Abstract

The effect of change of load,gap between the pin and plate hole and frictional coefficient on the maximum contact stress was studied. FEA result was compared with several formula calculation results. When the gap of pin and hole△R = 0,the average bearing stress formula can be adopted; when the ratio of gap between the hole and pin to radius of the pin λ≥0. 02,in order to save cost for FEA analysis the Hertz formula can be adopted if no other more accurate calculation methods are available The computing error between the Hertz formula and FEA is less than 10%.
