Objective To develop a swing bed for warm bath and mixing of in-vitro diagnostic kit. Mothods With CAD technology, 3D modeling of the swing bed mechanism was built, and Abaqus was used to do the modal analysis on it . An ADAMS simulation model of the swing bed mechanism was made. Motion law and states of the shaper mechanism were educed by its kinematical simulation. Results According to simulation analysis, the intrinsic frequency and the vibration modal were gotten. The curves of displacement, velocity, acceleration changes with time were given, and a theoretical basis for determination of working parameters and structural design parameters of a swing bed were provided. Thus design efficiency and quality could be improved; time and cost could be reduced. Conclusion An effective method for reasonable dimension design and structure optimizing design of shaper mechanism is provided. By using CAD/CAE technology, designers can analyze product performance rapidly and intuitively before physical prototype being made.
