The utility model discloses a terminal anti -swing test seat, including upper insulating seat, lower insulating seat and conductive terminal structure, the upper end surface of lower insulating seat is provided with the accommodation groove, the conductive terminal structure includes the action terminal and static terminal of setting in the accommodation groove, the one end of action terminal and static terminal elastic abutment, the lower end of upper insulating seat is provided with the anti -swing structure, and the anti -swing structure is used for action terminal horizontal limit, the bottom of accommodation groove is provided with terminal action groove, in the utility model, through setting the anti -swing structure in the lower end of upper insulating seat, can be in horizontal direction to action terminal horizontal limit, reduce the horizontal deviation of action terminal, thereby reduce the influence of the assembly precision of action terminal to its deformation amount in the test state, avoid action terminal after the probe insertion of test probe and cause the excessive deformation and lead to the original state of being unable to restore.

The application provides a tilting and rolling test device and a control method of the tilting and rolling test device. The tilting and rolling test device is used for providing a rolling platform for a ship model fixed on the tilting and rolling test device to simulate the rocking of a ship under the action of sea waves. The tilting and rolling test device comprises a controller, a base, a hydraulic actuator assembly and a rolling support. The base is fixed on the ground or a pre-buried base. The base and the rolling support are rotationally connected. The hydraulic actuator assembly comprises a hydraulic oil circuit system and an actuator driven by the hydraulic oil circuit system. The hydraulic oil circuit system is controlled by the controller, and the actuator is fixedly connected with the rolling support. The hydraulic oil circuit system is used for driving the actuator to move in a horizontal direction under the control of the controller, and driving the rolling support to tilt or roll through the actuator. The tilting and rolling test device and the control method of the tilting and rolling test device can accurately simulate the rocking of a ship to guide the design of the ship.

The utility model relates to the technical field of automobile accessory detection, disclose gear shift fork oscillation test frock, including shift fork foot, flat plate and shift fork foot support, one end of shift fork foot is equipped with the crash component, the outside of shift fork foot is equipped with fixed component, the crash component includes recessed groove, recessed groove fixed connection one end at shift fork foot, the outside fixed connection of shift fork foot support has convex groove, the inside setting of convex groove is at recessed groove, fixed component includes piston connection, piston connection fixed connection one end at shift fork foot, the inside setting of piston connection has connecting rod. In the utility model, gear shift fork oscillation test frock, simulate the durability test of gearbox actual gear shifting condition, after the appearance inspection and the analysis result of cutting inspection weld after the test, prevent batch welding to be bad to flow out, prevent the automobile gear shifting failure from being recalled due to the welding problem.
