Hello to everyone,
I want to make a 2dof udf of a 2d-rectangular(xy-axis). This rectangular got given mass, shear stifness(y-axis) , rotational stifness(θ) , Izz(moment of inertia, I think we dont need the other two moment for inertia, Iyy,Ixx, but in some 2dof udfs I ve seen that they use them), and maybe two depreciation rates(ξ), in the same axis with stifness. I suppose that it is a simple UDF but I need some help. P.S.1 The two degrees of freedom is y-movement and rotational movement(on the xy surface, around z-axis). The forces on the rectangular are: the weight, the two sprigns(stifness) and maybe two dumpers(in the same axis with stifness) P.S.2 I apologize for my english |
