Abstract

The invention discloses a mechanical refrigerator temperature control system simulation analysis method. The method comprises the following steps that (1) completing independent accurate modeling of all parts in a system in multi-physical-domain simulation platform software, motor design software and control system software; (2) integrating all independent modules in the multi-physical-domain simulation platform software, completing the construction of the whole system, realizing the joint simulation, obtaining a simulation experiment result, and comparing the simulation experiment result withan actual measurement result; And (3) carrying out temperature control principle analysis on the whole system. Actual measurement proves that when the temperature control effect of the mechanical refrigerator is analyzed, compared with an empirical method and a simple formula calculation method for temperature control analysis, the method has good convenience and an accurate simulation result.

Description
