本科毕业设计题目：重力势能驱动的“8”字型自控越障车设计摘要我的毕业设计题目是“重力势能驱动的“8”字型自控越障车设计”。
设计过程中小车的设计方法极其关键，首先论文思路要明确；而在设计过程中，选材、建模以及加工过程中要考虑充分。
我借鉴了一些现代发明理论例如对系统、参数的优化设计等；并采用了WINDOWS、MATLAB、PROE等辅助设计软件。
根据方案我将小车的机器构成分为六个部分，进行分步设计。
针对每一个部件设计切合的方案，通过筛选对比选出其中最好的方案组合。
我的方案最终确定为：选用三角底板式车架、锥形轴原动结构、传动结构选用齿轮或无需该机构、采用槽轮结构及曲柄连杆作为转向机构、行走结构采用单轮驱动实现差速、微调结构采用微调螺母螺钉。
在设计阶段我先建立了模型进行分析，利用TMATLAB对能耗、运动、动力及灵敏度等方面进行了分析。
进而获取了一部分有关小车运动的数据。
然后用PROE 三维软件模拟小车的实体建模以及模拟小车的部分运动。
根据方案我将小车的机器构成分为六个部分，进行分步设计。
针对每一个部件设计切合的方案，对塑料可采用切割，因为小车只是个试验模型，所以部分零件采用了木板、塑料等轻便材料，因为零件大多采用胶水衔接。
在调试过程中只需要微调便可改变小车参数，在设计阶段我先建立了模型进行分析，利用TMATLAB 对能耗、运动、动力及灵敏度等方面进行了分析。
方便试验的过程中验证小车运动规律，确立小车最优的参数。
