Control Cables are used in automobiles to transfer loads and motions as intended and required by the driver. These cables are supported at multiple points by clamps, which are mounted at suitable locations. The Clutch-cable is one of the cables routed through clamps mounted on the engine and the vehicle-chassis. During the vehicle’s travel on the rough road, the powertrain, supported by flexible mounts, tends to swivel, generating relative motion with respect to the chassis. As one end of the clutch-cable is mounted on the chassis and other on the vibrating engine, this relative movement contributes to the additional forces on the clamps. These forces, sometimes, lead to the clamp’s failure. Thus, the knowledge of load behavior is important for failure investigation and further optimization of the clamp design. The failure of the engine-mounted clutch-cable-clamp was observed in the vehicle testing on the rough road.
