A force compliant mechanism ( 750 ) for a force control system ( 600 ) includes a housing ( 752 ). A force compliant volute spring member ( 754 ) that has an input end ( 790 ) and an output end ( 792 ) is disposed within the housing ( 752 ). A force actuator input shaft ( 798 ) operates in response to a force induced thereon. An output shaft ( 800 ) is coupled to the output end ( 792 ) and to a test object ( 802 ). A force transducer ( 780 ) is in operative coupling with the force actuator input shaft ( 798 ) and generates a force signal in response to the induced force. A method of reducing force transients and increasing stability within a force control system ( 660 ) includes applying a force on a test object ( 666 ). A force actuator ( 669 ) is decoupled from the test object ( 666 ). The overall stiffness of the force control system is reduced and dynamic energy is absorbed via a force compliant member ( 662 ) coupled to the test object ( 666 ) and the force actuator ( 669 ).
