Multi-sample conditioning system

A system for applying mechanical stimulation to a plurality of samples, the system comprising:

• a plurality of sample chambers, each having first and second sample grips therein;
• a support structure for removably holding at least two of the sample chambers in fixed positions relative to an actuator;
• a push-bar assembly having mechanical couplings, along a first axis, for transmitting force from the actuator to the first sample grips of as many sample chambers as are coupled to the support structure;
• a reaction crossbar coupled to the support structure and having mechanical couplings for supporting the second sample grips of as many sample chambers as are coupled to the support structure;
• a flexure mounted to the support structure, the flexure allowing motion in a first direction with low friction and having high-rigidity resisting motion in at least one second direction;
• and
• a support rod having a linear axis, rigidly coupled at a first end to the push-bar assembly and coupled at a second end to the flexure;
• the flexure, through the support rod, allowing motion of the push-bar assembly parallel to the linear axis of the support rod and resisting rotation of the push-bar assembly in a plane defined by the push-bar's first axis and the support rod's linear axis.
