HITS   水平沖擊測試系統

Horizontal Impact Test System

Horizontal Impact Test Systems (HITS) simulate horizontal acceleration effects of vehicle braking and accelerating, rail switching, truck docking, and other types of horizontal impacts that occur during distribution and handling. Standard HITS models are specifically designed to test in accordance with ASTM D4169 Schedule G, ASTM D4003 and other corporate, industry and government specifications.

Custom HITS models are available that can perform tests in accordance with the Federal Motor Carrier Safety Administration’s (FMCSA) published Cargo Securement Rules, replicating the dynamics that a transported load experiences when vehicles are accelerating, braking, and turning.

High performance HITS are capable of replicating much higher energy events such as the horizontal impacts associated with crash or explosive events.

水平沖擊測試系統（HITS）能模擬車輛在制動、加速、軌道切換、卡車停靠以及其它在運輸和處理過程中發生的類似水平撞擊事件。符合ASTM D4169 ScheduleG、ASTM D4003標準和其他公司、行業和政府試驗測試規范。

定制版可以根據聯邦汽車安全管理局（FMCSA）發布的貨物安全規范進行測試，模擬當車輛加速、剎車和轉彎時運輸負荷的沖擊動力。

高性能版能模擬更高的能量沖擊事件，例如與車輛撞擊碰撞或爆炸事件相關的水平撞擊。

HITS Programmer 沖擊波形發生器

The HITS programmer design simulates a variety of cushioned draft gear railcar impacts or other low amplitude, long duration events. It consists of a pneumatic cylinder mounted to the seismic mass, a plunger with elastomer modules mounted to the carriage’s vertical bulkhead, and a pressure controller. The plunger and elastomers control the rise and decay of the trapezoidal pulse, and the cylinder controls the acceleration level, according to its internal pressure.

HITS沖擊波形發生器模擬產生各種緩沖齒輪軌道車撞擊或其他低振幅、長時間事件。它由一個安裝在消震質量上的氣動氣缸組成，一個裝有彈性體模塊的柱塞，安裝在車廂的垂直艙壁上，還有一個壓力控制器。柱塞和彈性體控制梯形脈沖的上升和衰減，柱體根據其內部壓力控制加速度水平。

HITS Reaction Mass 沖擊消振質量塊

The seismic reaction mass is a massive, solid steel structure which rides on rails and bearing which are independent from the carriage. It is restrained by a snubbing cylinder specially designed for the purpose. The seismic mass serves to isolate the high shock forces from the floor so that no large concrete foundation or buttress backstop is required.

消震反應質量塊是一個巨大的、堅固的鋼結構，它用軸承安裝在軌道上,獨立于裝載車廂。它用一個專門專門設計的圓筒固定。消震質量塊可以衰減高沖擊能量傳遞到地面來，這樣就不需要大的混凝土基礎或支撐結構。

HITS Propulsion System HITS推進系統

The carriage is accelerated by a long stroke pneumatic cylinder, the rod of which is permanently attached underneath the carriage. Before a test, the air supply is isolated from this cylinder and both ends are vented to atmosphere, making the carriage completely passive and safe to be approached for specimen loading and/or inspection. The brakes are also applied under these conditions, for additional safety. Just before a test, a large valve is operated to connect the aft end of the cylinder to a pre-charged air reservoir. When the brakes are released to initiate a test, air flows into the cylinder, the rod extends, and the carriage is accelerated to the desired velocity.
