A reversing vehicle follows the designed path
Hi In most vehicle dynamic analysis in MotionView/MotionSolve, the vehicle moves forward. However, I have a use-case which need the vehicle to move backward and also follow a designed curved path. I have succeeded in setting up the vehicle model which reverses along a straight line. By deactivating "Compute steering ratio"…

standard include file - location
Hi guys, sorry if this is a basic question, but I tried searching online and couldn’t find a clear answer. I am new to Altair/MotionSolve and I have a small problem. I was playing around with the settings and changed the standard include file. Now, when I open the program, I get an error(with and without checking the box).…

How do I correctly implement .tir Tire-files in HyperStudy when using a MotionView Model
Hello, I have a problem using .tir files when trying to setup my HyperStudy. Let me walk you through my approach. First I define my MotionView Model with the Solver Input File being a .xml. then I create three Parameterized Files, one for each Tire pair that is being used in my MV Model. The Resource is the .tpl file and…

Why do the tracks 'explode' at the beginning of my MotionView vehicle simulation?
Hi, I am trying to run a simulation in MotionView for a tracked vehicle towing another tracked vehicle. When I solve the run, however, the tracks on both vehicles seem to 'explode' (please see the attached short video). Note that this problem occurs when simulating a single vehicle, too.…

Building a 3-Wheeled Sidecar Vehicle from Scratch in MotionSolve – Where to Start
Hello Altair Community, I will be working on a 3-wheeled sidecar design where the side wheel is also steerable. I need to build the model from scratch for a multibody simulation in MotionSolve, and this is my first project of this type, so I’m unsure about the best place to start. I already have the main kinematic points…

About roll center in motion view[FSAE]
Hi, I'm designing our teams suspension geometry on motion view. I applied hard points of the car but I'm having trouble with ploting rollcenter. I ploted as the screenshot below. I compared with adams/car and 2d sketch but it seems to be lower than the actual roll center. If you have any sugestion, please let me know.

MotionView's track builder for a rigid contact soil interaction doesn't keep meshing from HyperMesh.
Hi, I am trying to simulate a tracked vehicle on a rigid (non-deformable) road in MotionView. I have set up my vehicle using the process given in the Tracked Vehicle Modeling tutorial (link: Tracked Vehicle Modeling) but diverge from the tutorial at the 'Soil Interaction' step (step 3.10). Here, I use the 'Rigid Contact'…

Can someone help me send some suggestions about Altair software to the development team？
I mainly engage in structural analysis and multi-body dynamics analysis. As an engineer who frequently uses Altair simulation software, the transition from old interface to new interface has shown me a revolutionary change in CAE software. However, there are some small features that I think may require better development…

粒子のパラメータ設定に関する質問
現在，EDEM と Motion View を連携させて数値シミュレーションを行っています． 内容は，EDEM で粒子を容器内に充填し，Motion View で作成した物体をその上に落下させるといったものです． EDEM 側の接触モデルには Hysteretic Spring モデルを使用し，粒子材料にはシリコンゴムを想定しています． 文献に記載されている材料物性値（ヤング率，密度，摩擦係数など）を調べ，それらをそのまま EDEM の粒子パラメータとして入力して解析を行っているのですが，粒子を複数個容器に入れた状態で Motion View との連成解析を行うと，初期高度よりも高く跳ね返るなど，不自然な挙動が発生します．…

Some confusion about BUSH settings in Motionview
I currently have a device that is mounted on a rubber spring. I plan to model it using a bush, but I found that during startup, the device will flatten the bush under its own gravity, which is not in bush with the actual working conditions of the device. How do I set it up and apply a preload to the bush to counteract…

Exporting MotionView Simulation Results
Hello everyone, I've completed the kinematic simulation of the vehicle using MotionView. Now I want to export the overall slip rate of the vehicle during motion, rather than the slip of a single wheel. However, when exporting data in HyperGraph, I couldn't find the corresponding result data. Perhaps I don't know which…

Ball joint force analysis using wheel force transducer data
Hi everyone, I’m part of the Baja SAE team at the University of Sherbrooke. Last semester, we were able to run our BAJA with a Wheel Force Transducer (WFT). Since we want to reduce the weight of our suspension subsystem, we’re looking for a way to use the data collected with our WFT test directly in Altair MotionSolve. The…
