it is not match with tractive force V.s slip ratio for this particular soil type.

I have tried that, haven't got right number! looks very easy but I am struggling with this.

I want to measure the wheel slippage on the soil.and I knew the vehicle velocity!, I need the each wheel linear velocity.

I am wondering , why sensors have a difficulty to measure linear velocity online? traction force is the result of motor torque. if you think the question is too easy and don't want to answer it, plz dont write spam.

I have the vehicle and wheels dimensions and I calculated the normal force acting on each wheel. There is a slippage for each wheel on the slope. (Wheel Traction force – wheel resistance force – wheel mass * g* sine (slope angle))/ Wheel mass= wheel acceleration So I can find wheel velocity...

Assume a vehicle with four independently driven in-wheel motors on slope. How can I calculate each wheel velocity? By knowing, the vehicle velocity, slope angle and each wheel torque. thanks,

Is there any idea or thought? Thanks.

why ansys workbech doen't show the defomred mesh in the graphics interface solution? is there any way to show the deformed mesh caused by load?

does any one know how to get angular velocity of the flexible body in ansys workbench? many thanks

does " mass moment of inertia" of flexible body such as tire change during the motion? Assuming the tire runs on soft ground without any deformation then goes on hard surface which cause deformation.

Can we use the maximum normal stress (at maximum wheel sinkage) which applies to a wheel surface (contact area between soil and wheel) as a cone index (CI)?

I need an amount of slip which is function of tractive force. tractive force is a force that the terrain can support before slip happens. Slip equals to s= 1-(actual speed of tire/theorical speed of tire). i have got the theorical speed but is very difficult to calculate the actual speed...

a vehicle moving on a sandy slope. Is there any method to calculate the amount of soil slip on a slope? I knew, we can find 100% slip (when vehicle sliding down) by friction force. But I want to know the amount of slip during vehicle movement. many thanks,

I found that,,,,CNCHECK ....is initial information in contact tool? if it is: rough wheel-ground... contact side>>>>" contact" and status>>>closed rough wheel-ground.....contact side "target" and status>>>Inactive. I have done simulations for "frictional" as well. with the same initial...

I am working on workbench ,,,where can I find CNCHECK and RID? should I use "Rough connection" for initial contact as well? or must be another connection option?
