Application: Spring Coupling for Heavy Duty Off-Road Vehicles & Equipment
Problem: Couplings were experiencing field failures due to spring breakages. Traditional spring design software claimed the design should perform well under the given working conditions.
The MWI Solution:
- Studied the mechanics of spring design, the forces at work in the given application, and the assumptions used in the traditional software
- Created a proprietary spring design model that more accurately predicts the performance of a cold-set spring
- Utilized the new model to design a replacement spring for the application
- Developed a secondary process protocol for coupling spring components
A new spring was designed using the proprietary model, the spring breakage issue was resolved, and the customer has re-evaluated and updated all of their spring designs utilizing the new model.
