b. When conducting the above-mentioned independent test, the environmental test equipment and the vibration test equipment must be separated;
Each time, the connecting parts have to be removed and moved, which is a tedious task.

c. In preparation for conducting the above-mentioned independent test, a large space is required to separate and separate the environmental test device and the vibration test device. Also,
Therefore, when the equipment is installed in a small space, for example, the condenser of the refrigerator that makes up the environmental test equipment is placed next to the wall of the building, resulting in insufficient ventilation and a problem in that the cooling capacity decreases. . Moreover, the work space becomes narrower, and work efficiency decreases.

d. When conducting a complex environment test, the test chamber can only be opened and closed at the front, making it difficult to attach the test object to the excitation axis in the test chamber, and depending on the shape, size, etc. of the test object. In this method, both test apparatuses have to be separated, the test object is attached to the excitation shaft, and then the excitation shaft must be placed in the test chamber together with the test object, which is extremely inefficient.

Therefore, the present invention eliminates the need to separate and move the environmental test device and the vibration test device when performing either the environmental test or the vibration test alone, and therefore provides a rail device for moving either of the two devices. is not necessary. It simplifies the preparation work for individual tests, greatly saves installation space for equipment, and does not interfere with the operation of refrigerators, etc.
Another purpose is to provide a complex environment test device that can be installed with plenty of room so as not to hinder workability, and that allows for easy attachment of test objects to the excitation shaft when conducting complex tests. do.
