Mechanical experimental device and method for conducting experiment by applying same

Abstract

The invention provides a mechanical experiment device applied to the technical field of experimental equipment and also relates to a method for conducting an experiment by applying the experimental device. One end of the bottom of an upright post (2) of the experimental device is connected with a base (1); the other end of the upright post (2) is connected with a cross beam (3); weight support bar plates (4) for placing weights (28) are respectively arranged at two end parts of the cross beam (3); strain gauges (29) are respectively attached to parts, positioned on two sides of the upright posts (2), of the cross beam (3); each strain gauge (29) is connected with a static resistance strain indicator (5). According to the experimental device disclosed by the invention, multiple mechanical experiments such as bending normal stress determination of the cross beam, a bending combination deformation experiment, an internal force determination experiment of a truss, internal force determination of a statically determinate structure, internal force determination of a statically indeterminate structure and the like can be performed conveniently and quickly; besides, the steps are simple and convenient, and the operation is simple, so that the experiments can be finished conveniently and quickly and the experiment result is accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and more specifically, relates to a mechanical experimental device, and also relates to a method for conducting experiments by using the experimental device. Background technique [0002] Among the experimental devices commonly used in the experimental teaching of structural mechanics, the experimental devices related to rigid frame or truss are more common, and their common feature is that the structure type of the device cannot be changed during the test. Therefore, when different experiments are performed, different experimental devices need to be made, which not only increases the test cost, but also requires the use of different experimental devices when conducting different experiments, which also increases the laboratory space and affects the use efficiency of the experimental site. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present inventi...
