HITS   程度(du)打击测试体系

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.

产物特色 Features Highlights:


HITS Programmer 打(da)击波形发生器

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打(da)击(ji)波形(xing)发(fa)生器摹(mo)拟(ni)发(fa)生各类缓冲齿(chi)轮轨道车撞击(ji)或其(qi)余低(di)振幅、长时(shi)候事务。它由一(yi)个(ge)装(zhuang)置在消(xiao)震品质上(shang)的(de)(de)(de)(de)气(qi)动气(qi)缸构(gou)成,一(yi)个(ge)装(zhuang)有弹性体模块(kuai)的(de)(de)(de)(de)柱(zhu)(zhu)塞,装(zhuang)置在车箱的(de)(de)(de)(de)垂直舱壁上(shang),另有一(yi)个(ge)压力(li)节(jie)制器。柱(zhu)(zhu)塞和弹性体节(jie)制梯形(xing)脉冲的(de)(de)(de)(de)回升和衰减,柱(zhu)(zhu)体按照其(qi)外部压力(li)节(jie)制加快率程度。


HITS Reaction Mass 打击消振(zhen)品质块

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(fan)映品质(zhi)块(kuai)(kuai)是一(yi)个庞大的、坚忍的钢布局(ju),它用轴承(cheng)装(zhuang)置在轨道上,自力于装(zhuang)载车箱(xiang)。它用一(yi)个特(te)地特(te)地设想的圆筒牢固。消震品质(zhi)块(kuai)(kuai)能够衰减高打击能量通报到空中来,如许就不须(xu)要大的混凝(ning)土(tu)根(gen)本或撑(cheng)持(chi)布局(ju)。


HITS Propulsion System HITS鞭策体(ti)系

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.

HITS Carriage 装(zhuang)载车箱(xiang)

The carriage is a rigid weldment with a solid horizontal surface and an integral vertical impact surface (“bulkhead”) at the forward end. The vertical structure simulates the end of a railcar or trailer, and is designed to resist the horizontal impact loads of packages and products. Each of the surfaces (horizontal and vertical) are fitted with threaded inserts for the mounting and securing of test specimens.

车箱刚性焊接,包含(han)一个实心的(de)(de)程度(du)台(tai)面(mian)和(he)(he)一个前(qian)端(duan)全体式垂(chui)直打击面(mian)(“舱壁”)构成。垂(chui)直打击面(mian)布局摹拟了轨道车或拖车的(de)(de)结(jie)尾,用来抵当包裹和(he)(he)产物的(de)(de)程度(du)打击。每一个面(mian)(程度(du)和(he)(he)垂(chui)直)都预(yu)留(liu)了罗(luo)纹(wen)孔,便利测试标本装置和(he)(he)掩护。


HITS Guide Rails 导(dao)轨

Two precision guide rails secured to C-beams provide the horizontal support and guidance for the HITS carriage. Zero clearance recirculating ball bearings on the carriage allow the carriage to travel smoothly along the guide rails. The bearings are mounted underneath the carriage, resulting in a system with zero clearance specimen surface side access; the widest part of the system is the side of the carriage itself.

牢固在C梁上(shang)的两个紧密导(dao)(dao)(dao)轨,为碰撞车(che)箱供(gong)给程度的撑持(chi)和导(dao)(dao)(dao)向(xiang)。在车(che)箱上(shang)的零(ling)空(kong)隙(xi)轮回球轴承使车(che)箱在导(dao)(dao)(dao)轨上(shang)安稳地行驶(shi)。轴承装置在车(che)箱的下方,不影(ying)响实验产物装置,车(che)箱即为体系中最宽的局(ju)部(bu).
