BWS MMT1 Multifunctional Experimental Equipment

This product is mainly used for experiments conducted for Mechanics/Strength of Materials in Engineering institutions. Multifunctional Experimental Equipment provides a variety of experiments in the field of strength of materials by making some different adjustments to the equipment. The experiment enables students to learn the dialectical relationship between theory and practice but also enhances their practical abilities.

The load is provided by a spiral worm gear and measurement is performed for load using a force sensor and for strain using a strain gauge. The test bench’s structure is compact, the load can be steadily provided, and it is simple for students to operate. There can be obtained high-quality experimental results with this device. Other tests can be added to the device as needed. The strain instrument can connect to a computer where data acquisition and processing can be performed.

This product is designed with an enclosed steel frame and cast composition with careful surface treatment. It is a durable fastening structure. For each type of experiment, the product comes equipped with specimens and surface treated samples and accessories.

The system is composed of a base, pure bending specimen, sensors, strain instrument, strain gage, wires, and so on. The strain instrument can connect to a computer where data can be processed. Through the experimental test method, a few basic parameters in the mechanics of materials can be measured and analyzed, and the results can be compared with the theoretical values.

The basic principle of this strain-stress measurement method: measuring a specimen’s surface strain with a strain gauge, then the specimen’s surface stress is determined according to the strain-stress relationship. The strain-stress measurement method is not only used to validate the basic theory of mechanics of materials, to measure the mechanical properties of materials but also is a major engineering testing means for solving engineering problems. It provides a good experimental basis for scientific research.
