Energy-Absorbing Cab Support of Forest Machine

Abstract:

One of the requirements to the cabin of a forestry machine is the ability to absorb a certain amount of energy during deformation in the event of a rollover. The paper presents a method for increasing energy absorption of protective structure of a forestry machine cabin, enabling to reduce the risk of injuries to the operators in the event of an emergency. This is achieved by introducing into the structure of the protective frame of a cab energy-absorbing mounts in which the energy is absorbed due to plastic deformation of their elements in the event of a rollover of forestry machine. The article presents the design of the mount, describes the principle of its operation in the event of an emergency, and theoretical and experimental studies of the deformable mount. As the result of theoretical and experimental investigations the geometric parameters of the energy-absorbing mount are determined.
