【Abstract】 This paper presents in detail the basic structure and operating principle of a new type automobile crash simulation absorber based on the hydraulic rod control method, and gives the mathematical model of the system and the design method of the control rod. The velocity and acceleration data obtained from the tests agree with those of the actual crashes very well, and the device can be used for the study of a passive safety system, and the method can be used to design other absorbers.更多还原
