Summary of Technical Data on Grip Force and Power Metrics

This document presents experimental data related to grip force (pinch) and power measurements under various conditions, focusing on parameters such as rung position, sphere diameter, and cylinder diameter. The data is organized into several sections, each corresponding to a specific variable affecting grip performance.

1. Grip Force and Power vs. Rung Position

The first section analyzes grip force and power at different rung positions (denoted as h) on a ladder or similar structure. Key metrics include:

• Pinch@Anom and Pinch@Apeak: Pinch force at nominal and peak conditions.
• Power@Anom and Power@Apeak: Power output at nominal and peak conditions.

The data shows variations in grip force and power across rung positions 1 to 5, with values ranging from 0 to 120 N for force and corresponding power percentages.

2. Grip Force and Power vs. Sphere Diameter

This section examines how grip force and power change with sphere diameters ranging approximately from 0 mm to 90 mm. The parameters measured include the same pinch and power metrics at nominal and peak conditions. Payloads are indicated in grams (gk), showing the load effect on grip performance.

3. Grip Force and Power vs. Cylinder Diameter

Similar to the sphere diameter section, this part focuses on cylinder diameters from 0 mm to about 45 mm. The pinch and power metrics are recorded to assess how cylindrical object size influences grip strength and power output.

Key Observations and Recommendations

• Grip force and power vary significantly with the size and shape of the object being grasped (sphere vs. cylinder) and the position on the rung.
• Peak values of pinch force and power provide critical insights into maximum grip capabilities under different loading conditions.
• Understanding these variations is essential for ergonomic design, safety assessments, and optimizing grip-related tasks in industrial or occupational settings.

Note: The document primarily contains graphical data representations (charts) with force and power plotted against physical parameters. Exact numerical values are not fully extractable but trends indicate the importance of object geometry and position on grip performance.
