Explore the various vehicle modeling tools.
The vehicle library models most four-wheeled vehicles in production today. Models can be modified interactively in MotionView to support topologies that are not supported in the vehicle library. The vehicle library is open-source, ASCII-based, and can be modified by you. The methods in the vehicle library can also be used and adapted to model non-automotive land vehicles, such as tractors and trucks.
A widely used process in the automotive industry is to split the suspension design and development into three distinct stages. The stages are typically performed by different teams working in different locations and at different times during the vehicle program. Ideally, the teams will share model data, modeling methods, and results widely. Since the teams are working on the same vehicle, the engineering lessons learned by one group will need to be shared with the other two teams.
All of the MotionView models can be used in either a Design of Experiments (DOE) or Optimization study using the HyperStudy client in HyperWorks.
The rear suspension model is built using the same process as the front suspension. Eleven different rear suspensions are available using the Assembly Wizard.
The internal jounce bumper system is used to simulate a jounce bumper that is internal to the shock absorber, or strut, on a front or rear suspension. The system creates forces, requests, and graphics of the bumper. The force acts between the strut or shock rod and the strut or shock tube. The bumper is oriented using lengths along the strut/shock instead of XYZ coordinates. The force-deflection characteristics of the jounce bumper are defined by the curve in the jounce bumper system. In models built via the Assembly Wizard, the jounce bumper system is a child of the suspension system.
In the deformable strut system, the strut rod is modeled by beams and the strut tube to strut rod joint is modeled by a point to deformable curve constraint. This allows the strut to bend under load and captures the camber change due to lateral force common to strut suspensions.
Events create motions and forces in the model which make the system move. Most events add additional parts to the model to perform the simulation.
The Static Ride analysis is a simulation of both wheels moving up and down, in phase, with the steering wheel held fixed. The chassis is fixed-to-ground. The displacement of the wheel center is prescribed by the user. The suspension moves via a simple control system and a “suspension test rig”. The wheel is constrained at the tire patch location to the suspension test rig using an in-plane joint. Standard suspension requests (caster, camber, toe, etc.) are included as part of the ride analysis and are described here. The front and rear suspension ride analyses are similar.
The Task Wizard dialog allows you to select the analysis tasks to be run.
In MotionView, models are assembled from libraries of pre-defined systems using the Assembly Wizard, located on the Model menu. The Assembly Wizard dialog guides you through the assembly process, ensuring that your selections are compatible.
The attachments specified during the assembly process (using the Assembly Wizard dialog) can be modified using the Attachment Wizard, located on the Model menu. The Attachment Wizard dialog guides you through the process of modifying the model attachments.
The Set Wizard Path dialog allows you to select directories in which several files are stored.
