Abstract：To avoid extra torque sensor in isokinetic muscle testing system, a method was developed based on normal servo equipment with torque monitoring signal. Under velocity mode of servo equipment, encoder feedback signal was applied to design velocity close-loop controller, and isokinetic was implemented with high accuracy; muscle force was acquired through the transformation of torque monitoring signal attached in servo equipment. By using hardware-in-loop simulation, a whole isokinetic muscle testing system was constructed by introducing the software Simulink and the motion controller Quanser Q8. To verify the feasibility of this method, selected five college boys participated in the isokinetic muscle testing. The kinematic muscle parameters of their elbow joint motion were measured. Through comparing with public results, it showed that the peak torque (PT) and other indicators lie in the ranges of published indicators, which verify the practical value of the constructing method of given isokinetic muscle test system.
