ABSTRACT:
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).
