Customer Challenge
We helped to design a new grab pole, as the existing design did not give passengers enough area to hold onto.
The new design had to provide a solution that would help protect passenger stability whilst the train in motion.
Scope
- To replace the current handrail with one vertical pole with minimal impacts on the end wall trimming for all the eight cars in the set.
- Perform a finite element analysis (FEA) to ensure the deflection is within the acceptable range.
- Perform a bolt calculation using COBRA software.
Solution
- We designed the grab pole so that the changes to the end wall were minimal.
- Our team retained all clamping and fastening details as per the original design.
- We redesigned the mounting brackets for the top side fixation.
- FEA was carried out to ensure that the pole is stiffened enough for the load acting on it.
Features
- Design of the grab pole in vertical form to provides a better grip for the passenger
- Top fixation concept design with min impact to the surroundings
Benefits
- Minimum changes to the existing car body
- Top fixation part will work with all the eight car bodies
- Quick Turnaround time with end-to-end ownership
- Excel macros created for bolt calculation automation
