Full-scale-movement linear circulating accelerated loading test system

Abstract

The invention provides a full-scale-movement linear circulating accelerated loading test system. The full-scale-movement linear circulating accelerated loading test system comprises a machine frame, a guide rail, two or more rolling wheel sets and two chain transmission pairs, wherein a front walking and guiding wheel and a back walking wheel are fixed to the lower part of the machine frame through a lifting mechanism; the guide rail is arranged on the machine frame; the upper loading surface of the guide rail is a linear section; the lower loading surface of the guide rail is shaped like a boat bottom; the two ends of the upper loading surface and the lower loading surface are connected in smooth transition through curved sections; the guide rail adopts a box-type structure and is internally filled with a shock-absorbing material; each rolling wheel set comprises two loading wheels and a rolling wheel; the rolling wheel is positioned between the two loading wheels and is coaxial with the loading wheels. The full-scale-movement linear circulating accelerated loading test system adopts a design scheme that the chain transmission pairs drive the rolling wheel sets, a chain and the rolling wheel sets are assembled together through chain pin shafts and connecting components, and the axes of wheel axles of the rolling wheel sets are vertical to and intersected with the longitudinal centerline of the chain; the full-scale-movement linear circulating accelerated loading test system is simple in structure, high in reliability and low in using cost and maintenance cost; the distance from the loading wheel to the rolling wheel is small, the stress condition is good, noise is low, and the efficiency is high.

Description

technical field [0001] The invention relates to an accelerated loading test system, in particular to a full-scale moving linear cycle type accelerated loading test system. Background technique [0002] The existing full-scale 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...
