Benkelman deflection trabem / Beckman deflection instrumentum

Beckman trabem methodus est modus idoneam mensuræ ad elastica deflectionem valorem de via superficiem in static mollis tristique aut limo celeritate et potest bene reflectunt altiore robore via superficiem.

I) Praeparata ante test

(I) Reprehendo et servo vexillum vehiculum mensurae in bonam condicionem et braking perficientur, et strigare interiorem fistulam obvium certa incremento pressura.

(II) onus (ferrum cuneos vel universitates) in car piscina et ponderare totalis massa tergo axe cum terram statera, quod occurrit requiritur axe onus. Et axis onus est non mutata in driving et mensurae de car.

(III) metiretur ad strigare contactus regio; use a jack to jack up the rear axle of the car on a flat and smooth hard road, spread a new carbon paper under the tire, and gently drop the jack to print tire marks on the graph paper , Use a planometer or counting square method to measure the tire contact area, accurate to 0.1cm2.

(IV) Reprehendo in sensibilitate deflectionis MODULUS Dial indicator.

(5) When measuring on an asphalt pavement, use a road surface thermometer to measure the temperature and road surface temperature during the test (the temperature changes throughout the day and should be measured at any time), and obtain the average temperature of the previous 5 days (the daily maximum temperature and the minimum daily temperature) through the weather station. Mediocris temperatus).

(VI) recordum in materiae, structuram, crassitudine, constructione et sustentacionem de bitumine pavimentum stratum in constructione et reconstruction.

II) test gradus

(I) disponere mensuræ puncta in test sectionem, distantia quae pendent in test necessitates. Mensurae puncta in rota semita balteus via negotiationis lane et notatum albis pingere aut creta. (II) align tergo rota gap de test vehiculo ad locum de III ~ 5cm post mensuræ punctum.

(3) Insert the deflection gauge into the gap between the rear wheels of the car, consistent with the direction of the car, the beam arm must not touch the tire, and the deflection gauge probe is placed on the measuring point (3 ~ 5cm in front of the center of the wheel gap), And install the dial indicator on the measuring rod of the deflection gauge, adjust the dial gauge to zero, tap the deflection gauge lightly with Digitus et reprehendo an horologio morke redit ad nulla stabiliter. Deflexcionis meterti potest hinc aut utrinque simul. (IV) In scrutator spirat sibilus ad imperium ad currus ad procedere tardius, et dial indicator continues ad rotate deinceps ad viam superficiem deformationis augetur. Cum vigilate manus moventur ad maximum valorem, cito legitur initial L1. Et currus adhuc movere deinceps et manus vicissim in contrarium directionem post currus agit de deflectionis radii (supra 3m), flare sibilus aut fluctus a vexillum vexillum ad imperium in subsisto. Legere ultima L2 L2 Post vigilia Manus Rotate stabiliter. De deinceps celeritas currus sit de 5km / h.
