Force Amplification System 🛗
Designed and fabricated a force amplification system for 's elevator emergency brake system, addressing the need for an amplified pulling force in case of insufficient input force from the Electronic Actuation System (ESA).
🔍 Project Overview
- The project aimed to create a reliable amplification system that increased the input force by a factor of 2.5, meeting the safety requirements for elevators.
- Involved designing and assembling a system that fits within the constrained space provided, while achieving the required force amplification using a rack and pinion mechanism.
🔧 Design and Fabrication
The force amplification system was built using a rack and pinion design. Key components were carefully selected based on gear specifications, space constraints, and material strength.
- Used laser-cut wood and steel for structural components to ensure stability and precision.
- Incorporated a gear and rack system with a steel frame to ensure durability and meet amplification requirements.
- Created a test rig to simulate the system's functionality, verifying static and dynamic performance.
🧪 Testing and Results
The system was subjected to both static and dynamic tests to ensure that it met the desired force amplification and response time.
- Static Testing: Verified a consistent 2.5x amplification factor with input forces around 40N.
- Dynamic Testing: Measured time response and travel distance, achieving an average response time of 0.112 seconds.
- Results: Successfully demonstrated a force amplification factor of 2.58, surpassing the target.
