“…Wen et al [16] reported that increasing the content of the dispersion resistance agent helps to improve the washout resistance of fresh concrete. Zhang et al [18] investigated the slump and the suspension content of UNC affected by the water/binder ratio, the cellulose dispersion resistance agent, and the polycarboxylate water reducer, and the results showed that the factors affecting the slump of the UNC were in the order of the water/binder ratio, the content of the water reducer, and the content of the dispersion resistance agent; the factors affecting the washout resistance were in the order of the content of the dispersion resistance agent, the water/binder ratio, and the content of the water reducer. Zhang and Dong [12] investigated the effect of fly ash and silica fume on the workability and washout resistance of UNC using polyacrylamide as a dispersion resistance agent, and the results indicated that the washout resistance of concrete was sharply reduced when the content of fly ash exceeded 30% of the binders, while it was significantly improved by adding silica fume within 20% of the binders.…”

To ensure a limited washout loss rate and the self-compaction of underwater concrete, the mix proportion design of underwater non-dispersible concrete is a key technology that has not been completely mastered. In view of this aspect, an orthogonal test study was carried out in this paper on the workability, washout resistance, and compressive strength of underwater non-dispersible concrete. Six factors with five levels were considered, which included the water/binder ratio, the sand ratio, the maximum particle size of the coarse aggregate, the content of the dispersion resistance agent, the content of superplasticizer, and the dosage of fly ash. Using a range and variance analysis, the sensitivity and significance of these factors were analyzed on the slump and slump-flow, the flow time, the washout loss rate, the pH value, and the compressive strength at the curing ages of 7 days and 28 days. The results indicated that the water/binder ratio and the content of the dispersion resistance agent were strong in terms of their sensitivity and significance on the workability and washout resistance, and the water/binder ratio and the dosage of fly ash were strong in terms of their sensitivity and significance on the compressive strength. With the joint fitness of the test results, formulas for predicting the slump-flow, washout loss rate, and compressive strength of underwater non-dispersible concrete were proposed considering the main impact factors.

The gear test bench is important equipment for analyzing gear performance, detecting gear quality, and providing basic data for gear design and machining. In order to monitor the running state of the gear test bench, predict its running performance both timely and effectively, and guarantee its stable operation, a digital twin-based state monitoring method of the gear test bench is proposed in this paper. The state monitoring system of the gear test bench based on the digital twin model is constructed to simulate its normal running state in real time. On this basis, through the acquisition of physical information of the gear test bench, the developing of the state monitoring system, and the simulation of the digital twin model, the real-time state monitoring of the normal operation gear test bench is realized. The test results of the closed power flow gear test bench show that the digital twin simulation results of the gear test bench are basically consistent with it. The proposed state monitoring system can map the normal running state of the gear test bench, so as to realize the running state monitoring of the gear test bench.
