The invention provides a universal erection load
simulation device which comprises an erection load
simulation device, a lower fulcrum moving device, an upper fulcrum moving device and a safety protection device; the universal erection load
simulation device is mainly used in a vertical erection
simulation test under the practical working conditions of idle load, full load and unbalance load to test and verify the erection time, the erection angle and the erection position accuracy, to test and verify the power matching of a power supply, an erection controller and an erection electric cylinder, to test and verify the performances of the pushing force, the operation speed, the
level shifting stability and the gear shifting stability of the erection electric cylinder, and to verify the normal and abnormal power-loss
brake performances in the erecting and leveling processes; the motion process of an erection mechanism is simulated, a
motion parameter equation of each member is deduced, the overall process of change of the
motion parameter is accurately reflected, the stress and the displacement of main stress parts of a launching vehicle are intuitively truly known and predicated, a weak link of a
system is found out and improved, so that the requirements of
rapidity, stability, reliability, safety and the like in the erection process of a guided
missile are met.
