    MSC Adams Tire slipping

    Would you help me if I attach additional data? What exactly would you need?

    MSC Adams Tire slipping

    The shape of the graph is what I expecr, but wheel should not loose grip at a very small torque. In my case any torque that I apply to the wheel there is some kind of slip.

    MSC Adams Tire slipping

    So, I have made a quick straight event. As you can see, during acceleration weight moves backwards and during breaking fowards. At all time there is weight under the tire, but when I apply torque to the rear axle it still slips (It still pushes the car foward, but the wheel is spinning more...

    MSC Adams Tire slipping

    Hi! I am working with MSC Adams software. I have built a Formula Student model, which works fine, the only issue that i have is that contact between tires and road seems to not be correct. When I apply torque to the rear axis, the tire seems to slip way to much and I don't know how to correct...

    Assembly sudden steering issue

    So for the last few days I have been trying some things. 1. If I use standard steering system from the ADAMS template I still run into the same issue 2. For powertrain, tires and chassis I am using the default FSAE templates as well 3. Inputs and outputs are all connected as they should be 4. I...

    Assembly sudden steering issue

    Hi Greg, I've had seen that the Adams is unable to satisfy the constraint for: SphJnt/30. However I was hoping that there is some additional info in the log files that implies error in the steering / suspension. SphJnt 30 is actually a balljoint between steeringrod and upright (picture below)...

    Assembly sudden steering issue

    I am linking the acf file, as well as the video of the simulationhttps://files.engineering.com/getfile.aspx?folder=71952410-bcb4-4c70-b0f5-be509d207c51&file=SLD_test5.zip

    Assembly sudden steering issue

    Thank you for the answer. So, I am using a steering template that is psrt of the FSAE templates that you can find on the internet. I have only changed hardpoints, so I don't think there should be any issues regarding the steering? Or? I have ran a Straight-Line Drive instead. The result was...

    Assembly sudden steering issue

    Hi, For the past few months I've been trying to implement our Formula Student suspension into Adams Car FSAE template. Our formula car has so called decoupled suspension, so i had to make my own templates for front and rear suspension and ARB. My assemby behaves very weirdly and I cannot...

    Steering wheel force/torque values will be zero in function-expression references

    Hi, I am currently working on a full vehicle analysis. Kinematics and compliance simulation works fine (steering turns as it should). But when i run any of the dynamic events i ge t the same error: fdm::ActJoiMot Setting function on: jms_steering_wheel_angle(steering::steering_wheel_angle)...

    Largest increment in Testrig

    I am working on a model in MSC Adams Car. I have designed front and rear suspension for formula student car by myself and used FSAE templates for steering, chassis and wheels. I am trying to run Full Vehicle Analysis, but I get the same error everytime: The equation with the largest error was...
