摘　　要：结合实际装配中的物理约束以及虚拟装配的特点,分别在间隙配合、过盈配合及过渡配合条件下,讨论了装配过程中的偏移阻力和进行阻力,建立了基于单点力反馈的机械产品虚拟装配阻力模型;最终通过虚拟装配实例和评价实验证明,基于单点力反馈的机械产品虚拟装配阻力模型能够增强用户在虚拟环境下的沉浸感,并且能够有效地辅助用户根据力觉反馈感知不同的机械配合类型.Under the condition of three types of basic mechanical fits , namely clearance fit , interference fit and transition fit , the offset resistance and the ongoing resistance in assembly process are investigated on the basis of physical constraints of actual assembly and the characteristics of virtual assembly .Then , a one-point force feedback model is constructed to describe the resistances .Finally, the examples and the evaluation experiments prove that the proposed model can enhance the immersion of users in virtual environment and can effectively help users identi -fy different mechanical fits according to force feedback perception .
