SM1007 Didactic Bench For Studying A Thin Envelope Educational Training Equipment Mechanical Trainer Equipment
1. Equipment introduction
Features of the equipment: Teaching bench for learning thin films (SM107), allowing to study and analyze stress and deformation states of pressurized thin cylindrical envelopes.
The bench should be able to experimentally verify the theory related to the thin envelope by measuring the deformation of the cylinder wall at different points and following different directions.
The bench must allow for the following teaching work:
Longitudinal, circumferential, radial and biaxial stresses
Behavior of cylinders under open and closed end conditions
Use of strain gauges
Relationship between stress and strain in a cylinder and the value of the modulus E
Indirect stress and strain
Poisson’s ratio value in a cylinder
Calculation of shear stress anywhere in a cylinder using Mohr’s circle
Determination of principal strains using the “principle of superposition”
Effect of biaxial stress system
Sources of error in experiments
2. Technical parameters
(1) Input power: single-phase 220V 50Hz
(2) Weight: The total weight is less than 200 kg.
(3) Working conditions: -10°C~40°C, humidity <85%
(4) Size: 1100*480*380
