摘　　要：针对全国大学生工程训练综合能力竞赛命题"无碳小车"的要求,进行了创新结构设计,改变了一般齿轮定心啮合为变心啮合,导致后轮形成速度差使车体走似简谐波,从而达到转向要求。运用matlab进行了运动轨迹的模拟分析,结合工程实践,并设计制造出实物。实践表明,运行轨迹符合大赛要求,小车运行平稳,行程远,避障多。According to the proposition of the comprehensive ability competition of engineering training for the national college students called ＂Carbon-Free Car＂, the innovational structure design changing the general center mesh of the gear was carried out. This forces that the body could go like simple harmonic wave by the speed difference from the rear wheel, which leads to the gear requirement. This design does the simulation analysis of the motion trial by using the Matlab. This design uses the Matlab to do the simulated analysis of the motion trail, combine the engineering practice, and construct the real entity. On the basis of the prac- tice, the motion trail meets the competition requirement. The car moves smoothly, travels far, and avoids many harriers.
