The use of detailed wheel/rail contact models has long been frustrated by the complicated preparations needed, to analyse the profiles for the local geometry and creep situation for the planar contact approach. A new software module is presented for this that automates the calculations in a generic way. Building on many components developed by others, this greatly simplifies the running of CONTACT for generic wheel/rail contact situations. Fully 3-d contact search algorithms are implemented. This uses the contact locus approach, that's simplified for wheel-on-rail situations and extended to wheel-on-roller contacts. A main characteristic of the new module is its extensive use of the multibody formalism, using markers to represent coordinate systems, using a newly designed, generic, object oriented-like software foundation. The contact geometry is analysed twice; first for the location of contact patches, and then for the local geometry of the contact patches. The contact search starts from profiles in their actual, overlapping positions. This yields the extent of interpenetration areas as needed for the potential contact definition. Different strategies may be employed for the tangent plane needed in the planar contact method. Creepages are formed automatically using rigid body kinematics, including wheel and track flexible bending. Numerical results illustrate the viability, generality, and robustness of the approach. The extension to conformal contacts is presented in an accompanying paper.

长期以来，由于需要复杂的准备工作，详细的轮轨接触模型的使用一直受挫，无法分析平面接触方法的局部几何形状和蠕变情况。为此提出了一个新的软件模块，它以通用方式自动执行计算。基于其他人开发的许多组件，这极大地简化了通用轮轨接触情况下的 CONTACT 运行。实现了全 3-d 联系人搜索算法。这使用了接触轨迹方法，该方法针对轮对轨情况进行了简化，并扩展到轮对滚子接触。新模块的一个主要特点是广泛使用多体形式，使用标记来表示坐标系，使用新设计的、通用的、面向对象的软件基础。接触几何分析两次；首先是接触斑块的位置，然后是接触斑块的局部几何形状。联系人搜索从其实际重叠位置的个人资料开始。这会产生潜在接触定义所需的互穿区域范围。对于平面接触方法中所需的切面，可以采用不同的策略。爬电距离是使用刚体运动学自动形成的，包括车轮和履带的柔性弯曲。数值结果说明了该方法的可行性、通用性和稳健性。随附的论文中介绍了对保形接触的扩展。重叠的位置。这会产生潜在接触定义所需的互穿区域范围。对于平面接触方法中所需的切面，可以采用不同的策略。爬电距离是使用刚体运动学自动形成的，包括车轮和履带的柔性弯曲。数值结果说明了该方法的可行性、通用性和稳健性。随附的论文中介绍了对保形接触的扩展。重叠的位置。这会产生潜在接触定义所需的互穿区域范围。对于平面接触方法中所需的切面，可以采用不同的策略。爬电距离是使用刚体运动学自动形成的，包括车轮和履带的柔性弯曲。数值结果说明了该方法的可行性、通用性和稳健性。随附的论文中介绍了对保形接触的扩展。方法的通用性和鲁棒性。随附的论文中介绍了对保形接触的扩展。方法的通用性和鲁棒性。随附的论文中介绍了对保形接触的扩展。
