Abstract In the engineering industry，especially in the heavy engineering industry，there are notable economic benefits in the interference fit．Traditional computing method is not only too complicated，but also does not give objective appraisal of reliability for the interference fit．Therefore，the quality of interference fit is not high，and its application is restricted．The reliability for the interference fit is analyzed and it’s optimization is studied by reliability theory and optimization technique，the mathematical model is derived，the corresponding computer programs are worked out．Using the method and the programs not only can calculate reliability of interference fit，but can notably raise it by optim ization for interference quantity．

过盈联结的可靠性分析与优化
在机械制造，特别是重型机械制造中，过盈联结具有十分显著的经济效益，但传统的计算方法不仅复杂，而且无法对过盈联结的工作可靠性给出定量的评价，因此影响了过盈配合的工作质量，妨碍了过盈配合的广泛应用，从可靠性理论和优化技术出发，对过盈联结的可靠性进行分析，并对过盈联结可靠度的优化进行研究，建立了计算模型，编制了相应的通用计算机程序，该方法和程序，不仅可以对过盈联接的可靠度进行分析，而且可以对过盈量进行优化，有效地提高配合系统的可靠度。
