In modern missile launch systems, the operation of a launcher vehicle involves the close coordination of multiple subsystems, including hydraulics, mechanical dynamics, and control systems. Key functions of the missile launcher vehicle include vehicle leveling, missile erection, and pre-launch preparation, typically driven by hydraulic actuators and controlled by the onboard controller, which calculates hydraulic component control signals based on real-time status feedback. As subsystem integration increases, the exchange and transfer of different types of information and energy become more complex. Therefore, evaluating and optimizing the overall dynamic and static performance of the system, as well as assessing the impact of component failures on operational performance, becomes crucial before product finalization.

The Missile Launcher Vehicle Real-Time Simulation System Solution integrates hydraulic, mechanical dynamics, and control subsystems into a unified scheduling and management platform. By leveraging simulation technology to replace some physical experiments, the system significantly shortens development cycles, reduces costs, and enhances operator familiarity with overall system performance and fault-handling procedures. By injecting faults into subsystems, the system can safely evaluate how component failures affect overall launcher vehicle performance, enabling operators to practice emergency procedures and improving both training effectiveness and operational readiness.

Based on the HRT hardware-in-the-loop simulation platform, the system offers extremely high real-time performance. Even with complex second-order differential equations and trigonometric calculations, the ODE4 solver achieves simulation steps as short as 50 microseconds. The system uses a reflective memory real-time network with 400 ns node latency, low jitter, and end-to-end data transmission, supporting up to 256 nodes and long-distance transmission. Multi-node distributed simulation is supported, with automatic Simulink model partitioning and real-time inter-model communication. The platform also supports x86 and PowerPC heterogeneous processors, as well as CPCI, VME, and PCI bus target machines, enabling multi-model loading and synchronized simulation control.

Functionally, the system consists of real-time simulators, a simulation control host, and a reflective memory network. Three real-time simulators run models of the electrical control system, hydraulic system, and dynamics system to validate hydraulic control laws. The electrical control system can be replaced with physical hardware for hardware-in-the-loop simulation. The simulation control host designs system models in Matlab/Simulink, automatically generates executable programs, downloads them to VxWorks target machines, and manages the entire simulation process. Virtual instruments and curve displays provide real-time monitoring. The reflective memory network ensures synchronized clocks among the three simulators, maintaining consistent real-time distributed simulation data.

This solution is widely applicable for real-time simulation verification of missile launcher vehicles, multidisciplinary co-simulation, and evaluation of electromechanical-hydraulic system designs. By integrating complex dynamics, hydraulics, and control simulation, it provides safe, reliable, and efficient technical support for product development, operator training, fault analysis, and performance optimization.
