I now want to use the ISO8608 regulations to generate 3D road surface roughness. Is there any way to do this? And how to set the contact settings between my wheels and the rough surface?
The poisson ratio of 0.49900 exceeds 0.495 (the bulk modulus of 3.33333e+19 exceeds 100 times the shear modulus of 6.67111e+16) for the elastic material named steel. However, a hybrid type element is not used. This may cause convergence problems. It is recommended that you change the element...
I would like to ask if I am using a plug-in program to generate a rough surface. What function can I use to combine the rough surface with the surface of my bridge so that my bridge is rough?
I would like to ask if I want to use the rough function of interaction and encounter convergence problems, can I directly change the minimum value of the time increment to a smaller value so that the analysis can converge?
*friction,lagrange or *friction,rough may cause convergence difficulty when used in conjunction with the *surface behavior, augmented lagrange or penalty option. Use penalty friction instead.
How to deal with it
You have entered a zero or negative density value. Abaqus allows non-physical data; however, most applications expect a positive density value and greater than 1.00000e-36 .
4 nodes associated with rigid bodies have boundary conditions prescribed at nodes other than the reference node. These...
Currently, a vehicle with a single degree of freedom is built, and the mass block and the wheels are connected through springs. However, the wheels have no density. I would like to ask how to set up damping if I want to install it on this car?
I am currently building a single degree of freedom vehicle. The top is a rigid mass connected to a wheel by a spring, and the density of the wheel is zero.
I first added a gravity term so that the car could run on the bridge. After reading the acceleration on the spring and adding an inertial...
