Vibrating Concrete

Vibrating Concrete

Mechanical vibrators are instrumental in compacting newly poured concrete within formwork and around reinforcements. This process is essential to eliminate trapped air pockets and establish a dense concrete mass. One widely used method is vibrating by internal vibrators, often referred to as a poker vibrator or immersion vibrator. It is rapidly inserted through the full depth of the freshly laid concrete and slightly extends into the layer below it (which remains in a plastic state). Consistent...

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in...

Area of Science:

Biomechanics
Mechanical Engineering
Human Factors Engineering

Background:

Vibrations significantly impact wheelchair users' comfort and health.
Existing models may not accurately capture the dynamic response of seated wheelchair users to vibrations.

Purpose of the Study:

To develop a validated procedure for modeling wheelchair users subjected to vibrations.
To establish subject-specific design criteria for wheelchair seating and suspension systems.

Main Methods:

Acquisition of experimental data using a wheelchair simulator.
Development of a seated wheelchair user model using maximum likelihood estimation.
Identification and verification of model parameters using experimental datasets.

Main Results:

A two-segment rotational link model was found adequate for characterizing vibratory response.
Model parameters were successfully identified and validated against additional experimental results.
The developed model accurately represents the dynamic behavior of wheelchair users under vibration.

Conclusions:

The proposed modeling procedure provides a robust method for analyzing wheelchair user dynamics.
This approach enables the development of personalized design criteria for improved wheelchair ergonomics.
The model can inform the design of advanced wheelchair seating and suspension for enhanced user experience.
