[0011] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] Example 1

[0013] like Figure 1 As shown, a comprehensive test system for simulating centrifugal vibration in an embodiment of the first aspect of the utility model comprises a base 6, a first placement wheel 8 is fixedly installed on the left end of the top of the base 6, a weight 5 is fixedly connected to the bottom of the first placement wheel 8 by a rope, an electronic dynamometer 1 is fixedly connected to the lower end of the first placement wheel 8 by a rope, a second placement wheel 9 is fixedly installed on the right end of the top of the base 6, a test piece 4 is fixedly connected to the bottom of the second placement wheel 9 by a hook lock, an electronic angle meter 2 is fixedly connected to the lower end of the second placement wheel 9 by a rope, a vibration table body 7 is fixedly connected to the bottom of the inner cavity of the electronic dynamometer 1, and a vibration table surface 3 is arranged on the top of the vibration table body 7.

[0014] The weight 5 can be used to ensure that the weight accuracy meets the test requirements. The bottom of the base 6 is fixed to the vibration table 7 by bolts and does not participate in the vibration, ensuring that it is in a static stable state during the test. The first placement wheel 8 and the second placement wheel 9 can keep the weight 5 at a safe distance from the rope to reduce the friction during the vibration. During the vibration, the test piece 4 is always subjected to the pulling force of the weight 5, which is equivalent to the centripetal force received during the centrifugal acceleration process. The electronic dynamometer 1 and the electronic angle meter 2 can be monitored at any time through the monitoring system to ensure that the parameters during the test are stable. This solves the problem that the existing test system cannot complete the centrifugal vibration test of the test piece, does not have a large centrifugal force and vibration load resistance, cannot meet the requirements of large-size, large-mass and large-scale centrifugal vibration tests, may cause inaccurate detection results, greatly reduces the market share, increases the workload of users, and cannot meet people's usage needs.

[0017] The technical effect achieved by the above embodiment is as follows: the weight 5 can ensure that the weight accuracy meets the test requirements, the bottom of the base 6 is fixed to the vibration table 7 by bolts and does not participate in the vibration, ensuring that it is in a static stable state during the test process, and the first placement wheel 8 and the second placement wheel 9 can make the weight 5 have a safe distance from the rope to reduce the friction during the vibration process. During the vibration process, the test piece 4 is always subjected to the pulling force of the weight 5, which is equivalent to the centripetal force received during the centrifugal acceleration process. The electronic dynamometer 1 and the electronic angle meter 2 can be monitored at any time through the monitoring system to ensure the stability of the parameters during the test process, which solves the problem that the existing test system cannot complete the centrifugal vibration test of the test piece, does not have a large centrifugal force and vibration load resistance, cannot meet the requirements of large-size, large-mass and large-scale centrifugal vibration tests, may cause inaccurate detection results, greatly reduce the market share, increase the workload of users, and cannot meet people's usage needs.
