摘要： 文章基于职业院校轻量化人才培养竞赛，构建“以赛促教”产教融合模式，开发出整 备质量为 193 kg 的纯电动赛车，较初始方案减重 8%。通过“三电”（电池、电机、电控）系 统精准选型，采用 4130 钢管桁架与碳纤维车身实现轻量化，运用 ADAMS 软件优化悬架系统， 前轮前束角变化范围从 1.36°降低至 0.4°。ANSYS 仿真显示，车架扭转工况最大应力为 154.88 MPa，一阶模态频率为 29.49 Hz，可规避激励干扰。实车测试达成了 70 km/h 最高车速、 35 km 续航及 3 m 转弯半径，并且在 20 km/h 制动时无跑偏。研究验证了轻量化技术的工程可 行性，为新能源汽车提供“仿真－测试－制造”一体化技术路径，同时形成了可推广的产教 融合实践范式。

Abstract: Based on the lightweight talent cultivation competition in vocational colleges, this paper constructs a "competition-driven teaching" industry-education integration model and develops a battery electric racing car with a curb weight of 193 kg, which is 8% lighter than the initial proposal. Through precise selection of the "Three-Electric" (battery, motor, electronic control) systems, lightweighting is achieved using a 4130 steel tube space frame and carbon fiber body. The suspension system is optimized using ADAMS software, reducing the range of toe angle variation on the front wheels from 1.36°to 0.4°. ANSYS simulations demonstrate a maximum stress of 154.88 MPa in the frame torsional operating conditions and a first-order modal frequency of 29.49 Hz to avoid excitation interference. Physical vehicle testing confirmes a top speed of 70 km/h, 35 km range, 3 m turning radius, and stable 20 km/h emergency braking without deviation. The research validates the engineering feasibility of lightweight technology, proposes an integrated technical pathway of "simulation-testing-manufacturing" for new energy vehicle, and establishes a replicable industry-education collaborative practice framework.
