This paper makes a research on the overall design of elevating platform fire trucks and finishes simulation and mechanical analysis for main poles of At, summarizes on the analysis result, moreover, provides some arithmetic of typical methods of simulation. The author designs CAD software system that simulates elevating platform fire trucks. It realizes CAD of elevating platform fire trucks by the method of OOP and adopts parametric design, which helps to designers and enlarges the using area of the system. |
