Abstract

A hydraulic universal tester enabling to actively charge load on two ends of test piece is prepared for applying hydraulic cylinder with plunger-piston integrated action, connecting plunger to top frame formed by top horizontal beam and two smooth rods as well as flat plate of compression test bed, connecting piston to bottom frame formed by movable horizontal beam and two screw rods as well as bottom horizontal beam, using plunger to push top frame up and using piston to push bottom frame down for actively charging loads at two ends of test piece set between two said frames.

Description

technical field [0001] The invention relates to a universal testing machine for testing the mechanical properties of materials, in particular to a hydraulic universal testing machine, in particular to a hydraulic universal testing machine which actively loads both ends of a test piece. Background technique [0002] Universal testing machine is widely used in scientific research and teaching. With the development of computer control technology, sensor technology, new hydraulic control devices, and servo motor technology, microcomputer-controlled electro-hydraulic servo universal testing machines and electronically controlled universal testing machines have become leading products in the testing machine manufacturing industry due to their excellent testing performance and have become It is widely used in related industries. The more advanced hydraulic universal testing machine currently on the market is the WAW series microcomputer-controlled electro-hydraulic servo universal...
