Electrical Contact Resistance of Contact Bodies With Cambered Surface
Wanbin Ren, Chao Zhang, Xilai Sun
Abstract
The electrical contact resistance of cambered surface contact is systematically studied by analytical solution and finite-element simulation. Two representative cambered surface contacts, namely sphere-plane contact and cylinder-plane contact are built and the distributions of electrical current lines profile and isopotential are compared explicitly. Subsequently, the effects of size parameters of cambered surface and mechanical load on contact resistance are evaluated over a large range of aspect ratios. Furthermore, dissimilarity between sphere-plane contact and cylinder-plane contact is deduced.
