【摘要】：双钢轮振动压路机作为沥青路面压实的关键设备，其性能和压实质量直接影响着公路施工的质量与效率。近年来，国内外企业的同台竞争，使我国压路机市场的竞争愈演愈烈。通过对双钢轮振动压路机性能的评价研究，不但是正确认识双钢轮振动压路机整机水平和合理选择机型的理论依据；而且也有助于推动其在性能方面的全面提高，增强其竞争力。为此，本文提出双钢轮振动压路机性能评价体系的研究，，以便能够从科学客观的角度正确认识和评价双钢轮振动压路机的性能与质量水平，并指导实践应用。 论文通过对国内外双钢轮振动压路机的发展现状分析及技术性能差距的对比，并结合振动压路机相关的国家标准及行业标准，从压实性能、安全性、可靠性、经济性等方面对双钢轮振动压路机性能特点进行了详细阐述。在此基础上，结合两种指标筛选方法构建了二级递阶结构的性能评价指标体系，同时运用层次分析法，确定了评价指标体系中各指标的权重。 论文最后根据所建的评级指标体系和各指标权重，采用指标满足度指数模型，选择国外A企业、国内B企业、C企业和D企业中双钢轮振动压路机的代表机型进行了综合性能评价。并结合对各企业的实际情况分析与各机型的对比试验测试，验证了评价结果的合理性，证明了该指标体系与评价模型具有较好的可行性和实用性。
[Abstract]:As the key equipment of asphalt pavement compaction, the performance and compaction quality of double steel wheel vibratory roller directly affect the quality and efficiency of highway construction. In recent years, the competition between domestic and foreign enterprises has intensified. The evaluation and research on the performance of double-wheel vibratory roller is not only the theoretical basis for correctly understanding the level of the whole machine and the reasonable selection of the type of roller, but also helps to promote the overall improvement of its performance. Enhance its competitiveness. Therefore, this paper puts forward the research on the performance evaluation system of double-wheel vibratory roller, so that it can correctly understand and evaluate the performance and quality level of double-wheel vibratory roller from a scientific and objective angle, and guide its practical application. Based on the analysis of the development situation and the comparison of the technical performance gap between domestic and foreign double-wheel vibratory roller, the paper combines the relevant national standards and industry standards of vibratory roller, from compaction performance, safety, reliability, The performance characteristics of double-wheel vibratory roller are described in detail from the aspects of economy and so on. On this basis, combined with two index screening methods, the performance evaluation index system of two-level hierarchical structure is constructed. At the same time, the weight of each index in the evaluation index system is determined by using the analytic hierarchy process (AHP). Finally, according to the rating index system and the weight of each index, the index satisfaction index model is adopted to select foreign A enterprises. The comprehensive performance evaluation of the representative type of double steel wheel vibratory roller in B enterprise C enterprise and D enterprise was carried out. The rationality of the evaluation result is verified by analyzing the actual situation of each enterprise and the comparative test of each model, and the feasibility and practicability of the index system and the evaluation model are proved.
