摘要

摘要: 针对目前结构的设计易造成塑性变形时应力集中区域分布不合理的问题,通过有限元仿真技术,开展对侧翻保护装置在触地碰撞时其结构塑性行为的研究。以国产KZ-28型震源车侧翻保护装置为对象,研究其结构塑性变形区域分布规律,针对其结构应力集中易造成连接处破坏的现象,通过在结构上合理设置塑性铰孔的方法进行改善,并利用正交试验法选出塑性铰孔最优设置方案。仿真结果可知:设置有塑性铰孔的KZ-28型侧翻保护装置的应力集中区域分布更加合理,避免了对连接处的破坏,并且提升了整体吸能能力。通过合理设置塑性铰孔改善应力集中分布区域和提升吸能能力的方法为进一步提高侧翻保护装置结构性能提供了科学依据。

Abstract: In view of existing structural design being easy to cause the unreasonable regional distribution of stress concentration when plastic deformation,the plastic behavior of rollover protective structures when colliding the ground is researched by the finite element simulation. For domestic KZ-28 vibrator, the regular pattern for plastic deformation area of its rollover protective structure is studied; Aiming at the phenomenon of stress concentration of the structure being easy to cause joint damage, plastic hinge hole is set rationally to optimize the distribution of stress concentration; and the orthogonal experiment method is used to select the best schemes for plastic hinge hole. The simulation results indicate that the distribution of stress concentration area for the KZ-28 rollover protective structures set with plastic hinge hole is more reasonable than that without plastic hinge hole, avoiding the damage to the joints, and the overall energy absorption capacity is increased. Through setting up reasonable plastic hinge hole to improve the distribution of stress concentration area, the optimization method promotes energy absorption ability and improves the performance of structure for rollover protective structures.
