Discussion on the Design of An Off-road Vehicle Cab Chair Frame

For the development of the cab seat frame of an off-road vehicle, a forward development process for body parts was emphatically established and implemented, covering the whole process from design input, structural design, simulation analysis and test verification to technical status freezing.This research defined the key performance indicators and design control points of the off-road vehicle seat frame, and formed an engineering design scheme that meets the requirements of vehicle safety. It verified the feasibility and effectiveness of the proposed forward development process, as well as the consistency between simulation analysis methods and test results, confirming that the seat frame design is adaptable to the complex service conditions of off-road vehicles.Meanwhile, it provides a process template, technical basis and engineering practice reference for the standardized and efficient forward development of similar body seat components, and also strongly supports enterprises in improving the parts development system, shortening the development cycle and reducing research and development risks.
