Peak crush force
WebOct 12, 2024 · Tremendous initial peak force produces jerks and causes serious injuries to the passengers, and this problem arises exclusively in high impact energy absorbers. … WebPCF represents the initial peak crush force and a lower value is preferred to prevent instant deceleration, which is undesirable for crashworthiness. Consequently, CFE can be expressed using Eq. 3: 𝐶 = 𝑀𝐶 𝑃𝐶 = 𝐴 ×𝑃𝐶 = 𝑚 × 𝐴 𝑃𝐶 3 Where MCF is the mean crush force, is the crushing distance.
