Module test machine

A method for configuring a module test machine comprising:

• calculating a plurality of geometric parameters for a strut module based on a plurality of geometries of a vehicle configured to incorporate the strut module;
• determining road load data of the strut module along six axes of force;
• calculating a plurality of adjustable lengths of a plurality of arms of a fixture in the module test machine based on the plurality of geometric parameters, wherein the fixture is coupled to a frame of the module test machine and at most two actuators, a first end of the strut module is couplable to the frame, a second end of the strut module is couplable to the fixture, and the at most two actuators is configured to impart a plurality of loads along the six axes of force at the second end of the strut module;
• calculating a plurality of moment parameters based on the road load data;
• calculating at most two actuator vectors that control the at most two actuators based on the plurality of geometric parameters and the plurality of moment parameters;
• adjusting the plurality of arms to the plurality of adjustable lengths;
• and
• loading the at most two actuator vectors into a controller of the module test machine, wherein the plurality of adjustable lengths and the at most two actuator vectors are configured to replicate the road load data at the second end of the strut module while under test.

A module test machine comprising:

• a frame couplable to a first end of a strut module;
• at most two actuators that impart a plurality of loads at a second end of the strut module;
• a first swingarm that has a first arm with a first adjustable length coupled to the frame, and a second arm with a second adjustable length coupled to the frame;
• a second swingarm coupled to the first swingarm and couplable to the second end of the strut module, the second swingarm has a third arm with a third adjustable length coupled to a first actuator of the at most two actuators, and a fourth arm with a fourth adjustable length coupled to a second actuator of the at most two actuators, wherein the first actuator and the second actuator are configured to impart the plurality of loads along six axes of force at the second swingarm;
• and
• a controller configured to control the at most two actuators in response to at most two actuator vectors, wherein the first adjustable length, the second adjustable length, the third adjustable length, the fourth adjustable length, and the at most two actuator vectors are configured to replicate road load data at the second end of the strut module while under test.
