HITS   程度打击测试体系

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 打击波形(xing)发生器(qi)

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打击(ji)波形发(fa)生器摹拟(ni)发(fa)生各类缓(huan)冲齿(chi)轮(lun)轨道车撞击(ji)或其(qi)余(yu)低振幅、长时候事务。它由一个装置在消震品质上的(de)气(qi)动气(qi)缸构成,一个装有弹(dan)性体模块的(de)柱(zhu)(zhu)塞(sai),装置在车箱的(de)垂直舱壁上,另有一个压(ya)力节制(zhi)器。柱(zhu)(zhu)塞(sai)和弹(dan)性体节制(zhi)梯形脉冲的(de)回(hui)升和衰减,柱(zhu)(zhu)体按照其(qi)外部压(ya)力节制(zhi)加快率(lv)程度。


HITS Reaction Mass 打击消振(zhen)品(pin)质块(kuai)

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(xiao)震(zhen)反映品(pin)质(zhi)块是一个庞大的(de)、坚忍的(de)钢布局,它(ta)用轴承装置在轨道上,自力于装载车(che)箱。它(ta)用一个特地(di)特地(di)设想的(de)圆筒牢(lao)固。消(xiao)震(zhen)品(pin)质(zhi)块能够衰(shuai)减高打击(ji)能量通报到(dao)空中来,如许就不须要大的(de)混凝(ning)土根本(ben)或撑持布局。


HITS Propulsion System HITS鞭策体系

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.

车(che)(che)箱由一(yi)(yi)(yi)个(ge)(ge)长冲程的气(qi)动气(qi)缸加(jia)快,气(qi)缸鞭(bian)策杆与车(che)(che)箱下方毗(pi)连。在(zai)测试前,紧缩氛围供给体(ti)系与汽缸是分手(shou)的,气(qi)缸外部气(qi)体(ti)也(ye)排放(fang)到(dao)大(da)气(qi)中,使车(che)(che)箱完整宁静,以(yi)便停(ting)止产物装载和查抄(chao)。装载时刹(cha)车(che)(che)体(ti)系,也(ye)启(qi)动保(bao)障装载无危险。在(zai)测试之前,一(yi)(yi)(yi)个(ge)(ge)大(da)阀(fa)门(men)将鞭(bian)策体(ti)系尾部进气(qi)口毗(pi)连到(dao)一(yi)(yi)(yi)个(ge)(ge)事后充气(qi)的储(chu)气(qi)罐。当(dang)刹(cha)车(che)(che)被开(kai)释启(qi)动一(yi)(yi)(yi)个(ge)(ge)测试时,氛围会流(liu)入汽缸,气(qi)缸鞭(bian)策杆延长,鞭(bian)策车(che)(che)箱加(jia)快到(dao)想要的速(su)率。


HITS Carriage 装载车箱

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(che)箱刚性焊接(jie),包含一(yi)个实心的程(cheng)度(du)台(tai)面和一(yi)个前端全体式垂直(zhi)(zhi)(zhi)打击面(“舱壁”)构成。垂直(zhi)(zhi)(zhi)打击面布局摹拟了轨(gui)道车(che)或拖车(che)的结尾,用(yong)来抵(di)当包裹和产(chan)物的程(cheng)度(du)打击。每一(yi)个面(程(cheng)度(du)和垂直(zhi)(zhi)(zhi))都预留了罗纹孔,便利测试(shi)标(biao)本装(zhuang)置和掩护。


HITS Guide Rails 导轨

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梁上的(de)(de)两个紧密导轨,为碰撞车箱供(gong)给程度的(de)(de)撑持(chi)和导向(xiang)。在车箱上的(de)(de)零空隙轮(lun)回球轴承使车箱在导轨上安(an)稳地行(xing)驶。轴承装置在车箱的(de)(de)下方,不影响实验(yan)产物装置,车箱即为体(ti)系(xi)中(zhong)最宽的(de)(de)局部.
