摘要：

By　studying　ultrasonic　amplitude　transformers　to　meet　the　requirements　of　an　ultrasonic　vibration　cell　cutting　system,　a　new　compound　cone　step　type　amplitude　transformer　is　constructed.　Based　on　the　longitudinal　wave　equation　of　a　pole　with　varying　sections,　basic　parameters　of　the　compound　cone　step　type　amplitude　transformer　is　presented.　Size　of　the　ultrasonic　amplitude　transformer　is　derived,　and　the　ultrasonic　amplitude　transformers　is　designed　and　manufactured.　Normal　modes　in　the　pole　and　important　characteristic　parameters　such　as　resonance　frequency　and　position　of　the　displacement　node　are　obtained　using　the　finite　element　method.
