Spring Simulation
The auto-injector is becoming an ever more popular choice for patients and doctor wishing to replace the traditional injection method. However, the manufacturers themselves require lengthy iterations in the design process to determine the spring which produces an ideal injection time.
HST solves the challenge of multiple spring testing using Modal Control, that creates a composite channel to allow the applied load to vary with actuator position, as is representative of an actual spring. The user simply needs to specify the initial preload and spring stiffness in order for the system to adjust itself based on the actual load seen by the syringe, and can then determine if the chosen parameters for spring stiffness and preload have yielded an ideal auto-injector dispensing time for a given drug.
