Components Library

The Vehicle Tools in MotionView offers a set of components models commonly used in motorcycle, cars, trucks, and buses, such as springs, bushings, shock absorber, tire, and bumpstops.

Component models share the following features:

Components are ready to be connected in the model with no additional modeling requirements.
Predefined outputs are included covering most of the components desired results.
Parameters can be included in MotionView or accessed through a property file (TeimOrbit) independent of the MotionView mdl and MotionSolve input deck.

Table 1. Available Components
Entity	Function	Features
Air Spring	Limit force in suspension components Maintain ride height for large variations in load Absorb the impact from the vertical road inputs	Exerts a force along a line between two bodies Non-linear force versus deflection at different static inflation pressures interpolated from tabular data stored in a property file Set the initial load and spring height to determine the static inflation pressure
Helical Spring	Limit force in suspension components Absorb the impact from the vertical road inputs	Exerts a force along a line between two bodies Non-linear force versus deflection interpolated from tabular data stored in a property file Set the initial load or length of the spring at vehicle input position
Shock Absorber	Dissipate the energy stored in springs and damp the chassis motions	Exerts a force along a line between two bodies Include rebound and bump stops to limit the shock absorber actuation Non-linear force versus deflection interpolated from tabular data stored in a property file Linear force versus velocity
Mount Bushing	Elastically mount vehicle components to the vehicle chassis or body	Exerts force and torque all directions Non-linear force versus deflection interpolated from tabular data stored in a property file Linear damping
Frequency Dependent Bushing	Elastically mount vehicle components to the vehicle chassis or body	Exerts force and torque in all directions Stiffness and damping dependent on amplitude and frequency of bushing displacement Non-linear static force/torque versus deflection
Bump Stop	Limit suspension bump travel	Exerts a force along a line to repel two bodies when the distance between the bodies is less than a threshold Non-linear force versus deflection interpolated from tabular data stored in a property file Linear Damping
Rebound Stop	Limit suspension rebound travel	Exerts a force along a line to repel two bodies when the distance between the bodies is greater than a threshold Non-linear force versus deflection interpolated from tabular data stored in a property file Linear Damping
Rider	Model the mass and inertia of a vehicle driver and passengers	Adjustable height and body density Position knees, ankles, elbow, hip, hand, wrist, pelvis, neck to mimic different postures
Tire	Develop the contact forces from the ground for carrying vehicle load, steering, accelerating, and braking Isolate vibrations from small road irregularities	Altair Fiala tire Altair Soft-Soil tire CD-Tire Cosin FTire Siemens tire (MF-Tyre) Different road models support, including 3D and 2D, soft-soil, Curved Gridded Road (crg), Cosin RGR, CD-Tire, and point cloud data
