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.
