hello I thank this forum for it has resolved a lot of my issues and I have learned a lot from it and I appreciate the people who give help for free and without anything in return . my question is about the vibration analysis : is it possible to run vibration analysis for a model that has been...

I don't know why ??? but people here aren't responsive anymore maybe I have done something bad that I don't know about ….

hi I am co-simulating Adams/car and Simulink and in the Simulink i'd like to change the solver to fixed step while running the simulation because my Simulink model runs better with fixed step solver. the Adams/car solver is usually set to variable step while co-Simulating in Simulink . 1-...

Got the answer ! In the Road Builder > Road obstacles , Wavelength must be twice as the Length of the Sine Obstacle , the Altitude and the width can be set by yourself depending on the width and Altitude that you are looking for … cheers

hi how can I build a half-sine obstacle on a flat road in adams/car ? I have tried the 3d sine obstacle but whatever I do I guess I can't get it to become half-sine in Road Builder ... is it possible to make it half sine ? if so how ? when I give the road obstacle the wavelength that is the...

hi sorry I got my answer sorry for bothering you and here's adams tutorial :

hi Greg what i ment wasN'T that i need a force that acts in positive and negative direction with respect to it's reference coordinate system . let me explain more with a picture : I need to create such a force for the upper and lower part of my damper mounts in Adams/View … do I have to...

hi every one thanks for answering so many questions and helping everyone in so many difficult issues that they are facing with this software . as always I've got a question : how can I define a two-way force ( a force acting in both directions of the bodies it has been exerted on ) . I...

can you help me with this hydraulic circuit . I can't seem to figure out what is happening with the hydraulic models of the accumulators and valves and branches … i really need this and i don't know where to begin for a full car model ...

hi Greglocock sorry for replying so late … thanks for getting into it the name of the xml file is : 3d_road_obstacle_sine when I open the xml file the other coordinates ( other than x direction ) are zero 0 . so they don't change … how is it possible in a sine wave obstacle … when I...

this works too but can't adams give out road data file itself ????

so what do I have to do? does this mean that i should link adams and MATLAB for getting the height of the ground elevation for the road file ???? is this really going to be that hard ? i thought that this is only a matter of getting road data from an adams file spreadsheet or something ? (...

I went into the postprocessing and went to Tools>Clearance>Create then I got this : and I chose the ones you said I guess … is it right ? is itt what you said ? what should i do after this ?

hi for this matter I should first appreciate GregLocock for showing me a way to get what was really going on ... I did what you said and I saw that eventhough my predefined unit in adams and postprocessing was MMKS , only those two graghs that I mentioned earlier , had a different unit and...
