摘要

拉伸载荷是装甲车辆履带承受的主要载荷之一，是强度计算的重要工况，但是履带连接部件处的拉伸载荷分配尚不明确。为探究双销式履带板受拉伸时诱导齿与端联器上的载荷分配比例，针对某型装甲车辆履带板开展了单、双板履带板拉伸试验与仿真，研究不同块数履带板受拉伸载荷时载荷分配与应力结果的差异，并利用有限元法迭代计算确定履带受拉伸时稳定的载荷分配结果，提出一种快速计算履带板稳定载荷分配的两步计算方法。结果表明履带板拉伸载荷分配会随着履带板数目的增加发生变化，当履带板数目足够多时，端联器与诱导齿载荷分配趋向于1:2:1的分配比例。拉伸试验中履带数目的变化对履带板上最大应力以及履带销轴挠度均有一定影响，履带拉伸强度试验中应该加以考虑。

Abstract

Tensile load is one of the main loads on the track of armored vehicles and also an important working condition for strength calculation

but the distribution of tensile load at the connecting parts of the track is not clear. To figure out the load distribution ratio of double-pin track shoes under tensile load

single and double-shoe track tensile experiments and simulations of a certain type of armored vehicle track shoes were carried out

the difference in load distribution and stress when different numbers of track shoes were subjected to tensile load were discussed. The iterative calculation of the finite element method was used to figure out the results of stable load distribution when the track was stretched

and a two-step method to quickly calculate the stable load distribution of the track shoes was proposed. The results showed that: the tensile load distribution of the track shoes changes with the increase of the number of the track shoes; when the number of the track shoes is large enough

the load distribution of the end coupling and the guide tooth tends to have the distribution ratio of 1:2:1; the change of the number of tracks in the tensile test has some influence on the maximum stress on the track shoe and the deflection of the track pin

which should be considered in the tensile strength test of the track.
