Adjustable simulator apparatus and method for testing vehicle components

Various embodiments of an adjustable simulator apparatus for testing vehicle components are disclosed herein. The apparatus can be used to test linearly translatable components, such as transmission or brake components, without connecting them to every cooperating component as they would be in a vehicle. In one embodiment, an adjustable simulator apparatus includes a housing having a bore along a generally longitudinal axis and a first retainer and a second retainer disposed in the housing and spaced apart from one another. At least one of the first and the second retainer is adjustable in its position and a compressible member is disposed between the retainers. The apparatus further includes a piston translatable within the bore and a mechanical stop disposed at least partially within the bore of the housing and extends through the second end of the compressible member.
