摘要： A test fixture for mechanically testing breast implants includes a frame, a base plate coupled with the frame, and a first actuator coupled with the base plate for providing reciprocating motion to the base plate along a first axis. The test fixture includes a compression plate coupled with the frame that opposes the base plate, a second actuator coupled with the compression plate for providing reciprocating motion to the compression plate along a second axis that intersects the first axis, and a third actuator coupled with the compression plate for providing reciprocating motion to the compression plate along a third axis that intersects both the first axis and the second axis. The test fixture includes a control system in communication with the first, second, and third actuators for controlling the movement of the base plate along the first axis and the movement of the compression plate along the second and third axes.

摘要： A system of monitoring vibration of a blasting model test for a jointed rock mass and a method are provided. The system includes: a loading subsystem for three-way load, a model-surface blasting-vibration acquisition subsystem, and a model-interior dynamic stress-strain acquisition subsystem. The system and the method are provided, and a blasting model for a transparent jointed rock mass and a monitoring method that are obtained can analyze the influence of a joint inclination angle on propagation and attenuation laws of blasting stress waves in the jointed rock mass, and can analyze the influence of different millisecond blasting modes on the stability of an existing tunnel in the jointed rock mass, and can capture a real-time dynamic evolution process of cracks. The stress and strain measurement technologies used can perform omnibearing monitoring and recording for large deformations of surrounding rock under blasting load, and can resist the electromagnetic interference.

摘要： A whole-vehicle-based method for evaluating extreme pressure and antiwear properties of grease includes injecting the grease onto a key bearing pin and causing the engineering machine to operate without load is disclosed. The method includes causing the engineering machine to operate under a load of 10% to 150% rated load at least once, viewing and analyzing a wear condition of a surface of the bearing pin, and issuing a whole-vehicle-based evaluation report of extreme pressure and antiwear properties of grease. The engineering machine is caused to operate once under a load of 10% to 150% rated load for 0.5 min to 100 h.
