本文介绍了国产客货车轮强度有限元计算和分析。计算结果表明,在给定的计算工况下,客货车轮新轮的应力都在弹性极限以内,而当其磨耗到限时,部分工况下轮子的辐板轮毂交界处的应力超出弹性极限,所以应严格禁止超限车轮的使用。
This paper introduces the calculation and analysis of strength of domestic passenger and freight wheel by finite element method. The calculation results show that the stress of the new wheel of passenger and cargo wheels is within the elastic limit under a given calculation condition and the stress at the junction of the spoke and hub of the wheel under some conditions exceeds the elastic limit when the wear is limited. Therefore, the use of overrun wheels should be strictly prohibited.
