摘要

针对铰接装置力学性能试验的问题，简要介绍了转动铰接装置、固定铰接装置和自由铰接装置的结构与原理，基于工作原理设计了转动铰接装置“垂向+偏摆”、固定铰接装置“垂向+扭转”和自由铰接装置整体拉压3种新型部件试验方案，并与传统方案进行分析比对，重点应用部件试验方案研究了铰接装置的疲劳和极限性能。结果表明，3种新型铰接装置试验方案设计合理，试验工况与车辆运行工况一致，部件试验能准确反映出铰接装置的力学性能、疲劳和极限性能均满足要求，试验结果与分析结果基本一致。

Abstract

Aiming at the problem of mechanical property test for articulated device, the structural principle of articulated devices of rotation, fixed and free was briefly analyzed, and three kinds of new component test schemes, i.e. rotation "vertical + yaw", fixed hinge "vertical + torsional" and free hinged device as a whole, were designed and compared with the traditional ones. With the component test program, the fatigue and ultimate performance of the hinge device was studied. The results showed that the design of the three new articulated devices test scheme was reasonable, and the test conditions were consistent with the vehicle operation conditions. The component test could accurately reflect the mechanical properties, fatigue and ultimate performance of the articulated device which could fulfill the requirements. The test results were basically consistent with the analysis results.
