Innovative office chair concept

Morten Mogensen, M.Sc. in Industrial Design, recently developed an office chair concept in his master thesis at Aalborg University, Denmark, using AnyBody throughout the design process.

 

Starting with AnyBody simulation studies on support of the body, suitable positions and human movement in chairs Morten came up with a list of functional design criteria for fixed and moving parts of his chair. Subsequently the optimization facilities in AnyBody were then used to select the physical test models needed for the final design verification.

The end result is an innovative office chair concept with a documented approach on the human ergonomics developed in a cost-effective way in a short time frame.

Tips and tricks #11: Norm measures

The AnyKinMeasureNormComb object integrates several measures into one single measure; in this example one for each grey sphere representing its distance to the red surface.


 
Please note that this is not a traditional surface to surface joint, but in some cases it can be used instead. When using this measure, the parameters of the measure should be carefully adjusted. the Contact can be more or less rigid and exact depending on the parameters of the AnyKinMeasureNormComb.

ETS shoulder prostheses

 

The background of the work is that patients with total rotator cuff deficiency function rather poorly with the current prosthesis designs and typically will not be able to comb their hair or brush their teeth. It is the hope that systematic simulation may enable us to develop a superior prosthesis design to improve this situation.

Twente lower extremity model

The AnyBody Group is continuing a fruitful cooperation with the University of Twente through Karin Gorter, a Dutch master student, who is currently visiting the group.

Karin is implementing a new lower extremity model based on a set of consistent anatomical data collected recently by Martijn Klein Horsman, a Ph.D. student from Twente. After an initial data check and validation we expect that this model will make its way into the repository and replace the existing lower extremity model.

Muscle and joint forces in the shoulder

Alexander Nolte, a German student at Trauma Center Murnau, Germany, and Paracelsus Private Medical University Salzburg, Austria, recently completed his Diploma thesis Analysis of the muscle and joint forces in the shoulder joint using the AnyBody simulation model.

In contrast, the simulation of the flexion indicated much larger forces than Bergmann measured and a rotated force vector pointing into the socket of the joint. Alexander speculates that the cause for this discrepancy between  model and experiment might be due to some muscles not functioning in the patient after surgery or that the motion in the collarbone-scapula and sternum-collarbone joints were not taken into account in the simulation.
