This application relates to the field of insulation testing and discloses an insulation testing connection device and an insulation testing system. The insulation testing connection device includes a housing, a switch assembly, a control assembly, and a power supply assembly. The housing includes a wall and a first chamber and a second chamber formed by the wall. The wall includes terminals for the device under test and terminals for the testing instrument. The switch assembly is located in the second chamber and connected between the terminals for the device under test and the testing instrument, used to control the on / off state of the terminals for the device under test and the testing instrument. The control assembly is located in the first chamber and connected to the switch assembly. This solution addresses the problems of complex operation and susceptibility to errors. By setting the control assembly to control the on / off state of the switch assembly, and thus controlling the on / off state of the terminals for the device under test and the testing instrument, selective testing between the device under test and the testing instrument is performed without the need for repeated plugging and unplugging, simplifying operation.

This invention provides a six-degree-of-freedom simulator for low-gravity landing cushioning, comprising a landing leg assembly, a frame, an IMU, an air-bearing ball bearing, and a connecting column forming an attitude control platform and a translational platform. Four landing leg assemblies are evenly arranged on the frame. An air-bearing ball bearing is located in the middle of the frame, with an IMU mounted above it. The lower part of the air-bearing ball bearing is connected to the translational platform via the connecting column. A control component is also provided on the frame, and the landing leg assemblies and IMU are connected to the control component. The planar air cushion of the translational platform is used for support on a simulated tilting platform, and the landing leg assemblies act on the simulated landing surface. This invention can record attitude changes and the force and torque values ​​of the landing legs during landing, and compare the experimental data with simulation results from a full-physics simulation test.

The utility model belongs to the technical field of metro vehicle detection, particularly relates to a relay testing device for a metro, and provides the following scheme for solving the problem that the testing efficiency is greatly reduced in the testing process due to the fact that testing personnel need to frequently disassemble, place and reinstall a relay shell during detection and testing operation. Comprising a test equipment body and a relay body, the top of the test equipment body is fixedly connected with a mounting frame, the mounting frame is provided with a convenient test module, and the top of the mounting frame is provided with a resistance test module. The relay testing device for the subway has the function of improving the testing efficiency of the relay for the subway, the external shell of the relay can be automatically disassembled and removed through the device when the relay testing device is used, reset installation can be carried out after testing, the operation complexity degree of testing operation is reduced, testing operation is simplified, and the testing efficiency is improved. And the use effect of the device is improved.
