Title The design of a two-degree-of-freedom lifting mechanism
Abstract
Automated ammunition loading system is an essential assembly for modern large caliber artillery. This paper studies a two-degree-of-freedom lifting device, which is the main sub-assembly of an advanced automated ammunition loading system . The usage of this lifting device in automated ammunition loading system is discussed. According to the given performance parameters and technical specifications, the overall system design is completed, these design works include chain transmission design, guideway design, and the rotary mechanism design, a dynamic simulation based on ADAMS package is also carried out.
The principal works completed by this paper include:
1. The 3-D structure of the two-degree-of-freedom lifting mechanism is designed by using Solidworks software, at the same time the three-dimensional solid modeling is built.
2. The simplified virtual prototyping model of the lifting device is created in ADAMS software, and the dynamic simulation is carried out.
3.A simplified dynamic model for the lifting device is derived, and the kinetic differential equations are obtained via the second Lagriange equantion. The equations are solved by Program C language with Runge-Kutta method, then the results are compared with the ADAMS software dynamic simulation’s results.
