Abstract
A force compliant mechanism () for a force control system () includes a housing (). A force compliant volute spring member () that has an input end () and an output end () is disposed within the housing (). A force actuator input shaft () operates in response to a force induced thereon. An output shaft () is coupled to the output end () and to a test object (). A force transducer () is in operative coupling with the force actuator input shaft () 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 () includes applying a force on a test object (). A force actuator () is decoupled from the test object (). The overall stiffness of the force control system is reduced and dynamic energy is absorbed via a force compliant member () coupled to the test object () and the force actuator ().
