Abstract

On basis of the simulation of the metal contact behavior under low temperature condition, an experimental device for metal simulation testing under low temperature was designed and fabricated; then its designing method, operation, key technological parameters, and points for attention in usage and components such as rolling testing bench, computer control system, cooling system which are introduced in detail. The testing machine has many advantages as follow: Range of -60～0 ℃ ambient temperature can be simulated steadily, which can be offset automatically and precisely through low temperature solenoid valve; The experimental speed of specimenⅠ/ specimenⅡ can be adjusted independently as well as the sliding rate.
