摘　　要：现有机械蓄能式高速压制试验机采用圆柱螺旋弹簧作为储能元件,虽然可以较好的满足实验科研要求,但是存在弹簧储能小,长期使用易出现弹性松弛的不足,为了提高弹簧储能和改善弹簧刚度的稳定性,提出采用碟形弹簧取代原有螺旋弹簧的方案,并根据设计要求对碟形弹簧进行选型设计,运用有限元技术进行分析和验证。研究表明,在相近的尺寸范围内,使用碟形弹簧设计方案比原有的螺旋弹簧的压制能量提高了126%,压制能量达到4000J以上,碟片弹簧选型具有合理性和科学性。The existing mechanical energy stored type powder high velocity compaction machine uses helical springs as the energy storage element,although it can better meet the requirements of the experimental research,there is defects of low energy and beingeasy to appear the relaxation when used for a long time,In order to improve spring energy storage and the stability of the spring stiffness,it selects the disc spring to replace the original helical spring. According to the design requirements for selection of disc spring design,uses the finite element technology to analyzed and validated,and studies have shown that in the range of similar size,compared with the original design scheme suppress energy of disc spring it increases by 126% and can reach more than 4000 J,and the selection of Disc spring is reasonable and scientific.
