Abstract

The invention provides a mobile linear circulating-type acceleration loading test system. The mobile linear circulating-type acceleration loading test system comprises a frame, a guide rail, more than one of rolling wheel groups and two chain transmission pairs. The guide rail is arranged on the frame, an upper loading surface on the guide rail is a straight-line segment, a lower loading surface is in a hull bottom shape, two ends of the upper loading surface and the lower loading surface are connected through curve segments in a smooth and transition mode, the guide rail is in a box type, and is filled with a damping material; each rolling wheel group comprises two loading wheels and a rolling wheel, and the rolling wheel is positioned between the loading wheels and coaxially arranged. The system employs a design scheme for driving the rolling wheel groups by the chain transmission pairs, a chain is assembled with the rolling wheel groups together through a chain pin and a connecting piece, the wheel shaft axis of the rolling wheel group and the longitudinal center line of the chain vertically intersect, the structure is simple, reliability is high, usage maintenance cost is low; loading wheelspan rolling wheel distance is short, the bearing condition is good, the noise is little, and the efficiency is high.

Description

technical field [0001] The invention relates to an accelerated loading test system, in particular to a moving linear cycle type accelerated loading test system. Background technique [0002] The existing mobile accelerated loading test system mainly has two types: linear reciprocating type and linear circulation type: [0003] Among them, the linear reciprocating accelerated loading test system realizes one-way loading, and the return journey is empty, so the test efficiency is low; when simulating environmental conditions, the environmental chamber that needs to be adjusted is large in size, difficult to transition, and consumes a lot of energy. [0004] The linear cyclic accelerated loading test system has high test efficiency because there is no return idle stroke; however, the loading part is driven by a linear motor plate chain, and multiple sets of steel guide wheels are guided outside, the structure is complex, the noise is large, and the heat is serious. Additional ...
