CAM Drum Test / Bump Test

A CAM Drum test or Bump Test setup incorporates cams of various shapes and sizes to recreate the dynamics of driving in different conditions. Discover the industry standard in wear and fatigue testing with our advanced Cam Drum technology and setup for EV 2W.

Graphic Box

During a bump test, an EV is subjected to controlled impacts or shocks that simulate real-world driving scenarios such as driving over potholes, speed bumps, or uneven road surfaces using cam profiles.

The bump test for Electric Vehicles (EVs) is a crucial evaluation method designed to assess the structural integrity, durability and robustness of vehicle chassis, shock absorber and suspension system, with the components and associated weight housed in the vehicle.

The impacts from uneven road surfaces can generate significant forces that may affect the stability and integrity of the vehicle’s components, especially the sensitive battery system.

Current Challenges in the Ecosystem 

Electric Vehicles (EVs) face unique challenges related to the integration and durability of the design, structure and overall vehicle architecture. The substantial weight of EV battery packs necessitates reinforced chassis and suspension systems, which can impact vehicle dynamics and efficiency. Moreover, the placement of heavy battery modules requires careful design to maintain optimal weight distribution and structural integrity during impacts.

How Can CAM Drum Solve the Above Challenges?

Electric Vehicle bump testing is an indispensable testing solution for automotive engineers and technicians. It ensures that vehicles comply with safety standards before they are marketed. This testing process identifies potential Challenges/limitation with a vehicle’s suspension, braking system, wheels and tires, and other components before they pose safety risks.

Regular bump tests allow manufacturers to confirm that their vehicles are both safe and dependable for consumers. CAM Drum testing helps in identifying potential weaknesses in a product’s design, material, and overall vehicle durability.
