[Purpos Due to the lack of industry standards in the solar greenhouse construction process, this paper has developed a parameterized design system and specified the structure of the vegetable and fruit solar greenhouse in Beijing area. [Metho The design system has been developed taking SolidWorks as a platform and VB as a development tool. [Result Its user interface is simple and friendly and designed results are reliable, which can increase the level of automation in solar greenhouse design process. [Conclusion This is a general-purpose system capable of realizing parameterized modeling of other structures like fruit trees and flowering plants simply through changing the proportionality factor.
[Purpos in order to solve design problems of the hole-punching system for the pot-seedling hole-punching machine, a system featuring reliable operation, simple structure and stable performance has been designed in accordance with working requirements. [Metho MATLAB is used for accurate calculation of the cam profile, with the calculated results imported to SolidWorks to produce cam profile curves. Such curves are then modified according to working requirements, thereby to build a 3D model for the cam mechanism. Finally, a 3D model for the complete hole-punching system is built with SolidWorks. [Result The hole-punching system designed herein is applied to the pot-seedling hole-punching machine and after performance test has proven to be able to meet working requirements and work reliably. [Conclusion The design of this system can provide theoretical basis and reference for related research.
