【Abstract】 The 9 movement plases of a new stretcher vehicle,semiautomatic stretcher vehicle are described. 13 key points are selected from the framework of the semiautomatic rescue stretcher vehicle to describe the movement of the vehicle. The matrix theory is utilized to solve the locations, velocities and accelerations at any point during the movement of the semiautomatic rescue stretcher vehicle. The maximum acceleration and the maximum saltation of the velocity during the movement can be found out through analysis to eliminate the impact and to keep the movement stable. The semiautomatic stretcher vehicle is more stable than existing stretchers, and it can lessen secondary injury and save manpower as well.更多还原
