| 英文摘要: |
| With the testing system of button's life span as background, according to the relevant national standard. a new
kind of design scheme on multi-position pressing mechanism was proposed, and its key technologies, such as design
method of constant-width cam mechanism with straight moving follower were introduced. Firstly, the overall mechanism
design scheme was introduced. Then. based on the theory of isometric profile, the mathematic model of constant-width
cam mechanism was established analytically, which was solved with Matlab. and the profile of the proposed constant-
width cam and the motion rules of the follower were obtained. Based on the above calculation results. the 3D modeling
was carried out by Pro/E. Finally, the dynamic simulations were conducted by ADAMS software, by which the validity
of the mathematical model and the feasibility of design scheme was verified. The obtained results provide theoretical
basis for the future prototype manufacture of multi-position pressing mechanism. and has certain significance for
engineering applications. |
