Universal erection load simulation device

Abstract

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.

Description

technical field [0001] The invention relates to a general erecting load simulation device. Background technique [0002] In modern warfare, due to the development of reconnaissance technology and the improvement of strike precision, the survivability of missile weapons has been seriously threatened. In order to improve the survivability and quick response capability of the missile weapon system, it is necessary to achieve rapid leveling and erection in order to shorten the reaction time of the mobile-launched missile. For example, Russia's SS-20 and SS-25 missiles use hydraulic pressure and gas assist to shorten the erection time to 30 seconds, and the missiles can be launched immediately after erection. According to reports, the fastest launch preparation time of these two missiles is 15 minutes, while the reaction time of the missiles in the ready-to-launch state is only 90 seconds. With the needs of military preparations, my country's missile weapons are increasingly mo...

Problems solved by technology

Obviously, such a design has a lot of blindness, and the calculation is often quite different from the actual, so the product performance is difficult to guarantee

[0004] At present, there are many researches on the modeling and simulation of missile launching devices, but there are few studies on the complete simulation of the dynamic characteristics of the vehicle-mounted missile erection process (including erection speed, mechanical characteristics, oil pressure characteristics, and structural compactness, etc.) , it is impossible to comprehensively study the response characteristics and motion characteristics of the erecting process system, and it is impossible to analyze the dynamic characteristics of the start-stop jitter and crawling phenomena that are prone to occur in the system during the working process
