Title Design of the drive device for high-speed collision test bench
Abstract
Time-varying mechanics are included in a variety of models, for example bridges, train tracks, conveyor belts etc. The study of time-varying mechanics has become an inevitable trend. Some theoretical studies need dedicated experimental studies as a basis for its powerful data. High-speed crash test sets is the equipment to achieve the study of time-varying mechanics, providing different experimental conditions for the experimental study of time-varying mechanics. Air pressure driving device is the driving part of the high-speed crash test sets, providing different velocities for the crash mass to achieve different vibrating conditions for the hanging stick. The experimental theory and the structure design of the drive device directly affect the reliability and safety of the hanging stick Time-varying mechanics experiments and are of great significance in the Time-varying mechanics experiments.
According to the adiabatic equation of gas, establish the basic gas drive equation. According to the theory of air pressure drive, establish the plan for designing the device. Build three-dimensional solid model of air pressure drive unit in a three-dimensional design software.
Establish the working block diagram of the drive device in simulink software to obtain the curve results of various physical quantities, testing the operating characteristics of the drive unit. Change the initial gas pressure of the working process to achieve different working environments.
Build the finite element model of the gas cylinder and the support, just for checking their strength and stiffness.
Keywords Time-varying mechanics driving device three-dimensional solid model simulation the finite element analysis
