摘要:

在地震等自然灾害发生时,道路上常常会出现大小碎石,而大小碎石影响抢险运输车的快速通行。在车辆底盘加装升降机构是解决这一问题的有效办法。然而,现有的升降机构升降方式较为单一,占用空间较大,不便安装在车辆下方。此外,还面临着不能随不同的工况进行灵活升降的问题。为了解决这些问题,基于变胞机构原理设计了一种变胞升降机构;建立变胞升降机构的虚拟样机模型,利用ADAMS软件进行构态变换动力学仿真实验,研究了车辆在构态变换过程中的动力学特性。结果表明,该机构具有变拓扑构型和变自由度的特点,能够根据工况的不同,以不同的构态完成工作任务;针对不同大小的障碍物,该机构可进行一级或二级升高,实现快速越障;该机构具有优异的可行性和稳定性。

Abstract:

In earthquakes and other natural disasters, there are often large and small debris on the road, which will affect the rapid passage of emergency vehicles. Installing lifting mechanism on the vehicle chassis is an effective way to solve this problem. However, the existing lifting mechanism lifting method is relatively single, occupies a large space, and is inconvenient to install underneath the vehicle. In addition, it also faces the problem that it can not be lifted flexibly with different working conditions. In order to solve these problems, this paper designs a metamorphic lifting mechanism based on the principle of metamorphic, which has the characteristics of variable topological configuration and variable degrees of freedom, and can complete the work task in different configurations according to different working conditions. For obstacles of different sizes, the mechanism can be elevated in one or two stages to realize rapid obstacle crossing. In this paper, after establishing the virtual prototype model of the metamorphic lifting mechanism, ADAMS software is used to carry out the configuration change dynamics simulation experiment, which investigates the dynamics of the vehicle in the process of configuration change and verifies the feasibility and stability of the mechanism.
