摘要:
基于有限元分析方法设计汽车精密电镀机械结构，并分析其力学性能。以汽车转向节为研究对象，采用ABAQUS参数化建模技术构建其三维几何模型，并进行几何简化。设计了HK-35锌镍合金电镀与纯锌电镀两种表面处理工艺，通过数值模拟对比分析不同镀层对转向节力学性能的影响规律。同时，制备标准试件开展盐雾腐蚀试验和划痕法结合强度测试，验证数值模拟结果。结果表明：在紧急制动及复合工况下，锌镍合金镀层的Von-Mises应力峰值为119.85 MPa，较纯锌镀层和碱性电镀锌层更低，其等效应变值为652×10?6，相较于纯锌镀层和碱性电镀锌层更低。试验数据证实，锌镍合金镀层在应力分布均匀性、应变性能及高应力区承载能力等方面均表现出显著优势。盐雾腐蚀试验进一步表明，该镀层具有更优异的耐蚀性能和镀层-基体界面结合强度，可显著提升汽车精密电镀机械结构的力学性能稳定性和长期使用可靠性。
Abstract:
Design a precision electroplating mechanical structure for automobiles based on finite element analysis method and analyze its mechanical properties. Taking the automobile steering knuckle as the research object, ABAQUS parametric modeling technology is used to construct its three-dimensional geometric model, and geometric simplification is carried out. Two surface treatment processes, HK-35 zinc nickel alloy electroplating and pure zinc electroplating, were designed, and the influence of different coatings on the mechanical properties of steering knuckles was compared and analyzed through numerical simulation. At the same time, standard specimens were prepared for salt spray corrosion testing and scratch method combined strength testing to verify the numerical simulation results. The results showed that under emergency braking and composite working conditions, the peak Von Mises stress of the zinc nickel alloy coating was 119.85 MPa, which was lower than that of the pure zinc coating and the alkaline electroplated zinc layer. Its equivalent strain value was 652×10–6, which was lower than that of the pure zinc coating and the alkaline electroplated zinc layer. Experimental data confirms that zinc nickel alloy coatings exhibit significant advantages in stress distribution uniformity, strain performance, and load-bearing capacity in high stress zones. The salt spray corrosion test further indicates that the coating has superior corrosion resistance and coating substrate interface bonding strength, which can significantly improve the mechanical stability and long-term reliability of automotive precision electroplating mechanical structures
