摘　　要：承受轴向受变载荷螺栓组联接,是螺栓联接中最重要的一种形式,其设计合理与否直接影响到机械产品的成本、寿命与效益等。本文运用可靠性理论与最优化设计技术,提出了承受轴向受变载荷螺栓组联接的可靠性优化设计方法。文中以压力容器的密封螺栓组为例,讨论了可靠性优化设计数学模型的建立方法,并给出了设计实例。The linkage between bolt group and accept changing axis orientation load, is one of the most important form of bolt link. Whether the design is reasonable will directly influence the cost, life, and benefit of the machine product. In this paper, the reliability optimal design method of accept changing load for bolt group link is offered, in the application of the reliability theory and technology of optimization design. With the airproof bolt group of the pressure vessel as an example, the method of the reliability optimize design of math model is discussed, and an example of the design has been provided here.
