Abstract
  • A consumer orientated simulation of rotary solenoid performance allows the user to determine what effects non-standard conditions will have on performance in a contemplated application. Typical variable conditions are: loads temperature and voltage. Three differential equations are used to describe the solenoid operation. Two of these are non-linear, second-order equations describing the helical motion. The third is a non-linear, first-order equation used to describe the flux-current relationship. The equations are solved on an Electronic Associates Incorporated 690 hybrid computer. Programming in the digital computer is accomplished by using the HYTRAN Operations Interpreter (HOI) language. This request-response language is specifically designed for hybrid computer compatibility. Although slower than other well-known languages, it is capable of performing many executive control functions while not producing any significant increase in overall problem solution time. Results indicate the performance in terms of axial and rotational displacement, axial velocity, coil current, and torque. After plotting these features against time, the proper curves are combined for a comparison with the nominal or standard performance. External load, temperature and under voltage increase the operating time, while over voltage has the opposite effect.
