Haversine-Based Framework for High-G Shock Simulation: Spectral Consistency and Compliance With Industry Standards

High-fidelity simulation of extreme high-gravity shock environments is crucial for aerospace and defense applications, yet achieving spectral consistency between laboratory pulses and real-world shocks remains challenging. This paper proposes and experimentally validates a haversine-based framework that bridges this gap by enforcing spectral alignment across both absolute acceleration (AASRS) and pseudo-velocity (PVSRS) shock response spectra. Through seven high-g tests (> 20,000 g), we demonstrate that haversine pulses exhibit superior spectral agreement with measured data compared to conventional half-sine profiles, achieving relative root mean square errors below 0.1 in 95% of cases. Furthermore, the framework ensures compliance with ISO 18431-4 and ANSI S2.62 standards, with AASRS slopes stabilizing at 9 ± 3 dB/Oct and spectral amplitudes within ±6 dB/−3 dB tolerances. Velocity variation errors are maintained below 9%, validating PVSRS as a critical resilience metric. This work establishes a standardized methodology for impact-resistant design and high-g test system calibration, advancing protective technologies in critical engineering fields.
