Abstract

Batychron is a flexible underwater bell patented by the Gdynia Maritime University as a device used in hydro-technics engineering for underwater transport and diving while maintaining the safety of human life. This study aims to present the methods and results of strength tests and the conducted analysis of the selection of the most appropriate method of joining thermoplastic polyurethane film (TPU) and polypropylene belts for underwater use to obtain a device with a specific buoyancy force. A universal testing machine with a hydraulic drive was used for the tests. Various methods of joining polypropylene belts were tested to select the most favourable in terms of strength properties. For this purpose, two types of materials were selected: the TE324 polyester belt and the TS501_50 style belt. Various connection methods have been used: without seams; zig-zag stitch, straight cross; cross stitch, straight longitudinal; cross stitch, straight transverse, in order to select a joint with the highest strength parameters. In addition, the tensile strength of individual types of belts was tested. The methods of joining the TPU film were verified. The obtained results allowed us to determine that the strongest bond of TE324 material is a straight, longitudinal cross stitch. This is related to the load distribution in the belts tested in laboratory conditions, but also reflected in their practical application. Thanks to the results obtained, it was possible to select the optimal methods of joining (connection) and the construction of Batychron.

摘要

巴蒂chron是一种灵活的水下钟罩，由格丁尼亚海事大学申请专利，是一种用于水工工程中的水下运输和潜水的装置，同时确保人类生命安全。本研究旨在介绍强度测试的方法和结果，以及对选择最合适的水下使用的热塑性聚氨酯薄膜（TPU）和聚丙烯带连接方法进行的分析，以获得具有特定浮力的装置。试验使用了液压驱动的万能试验机。测试了各种聚丙烯带的连接方法，以选择强度性能方面最有利的方法。为此，选择了两种材料：TE324聚酯带和TS501_50款式带。使用了各种连接方法：无缝；之字形缝合、直交叉；十字缝合、直纵向；十字缝合、直横向，以便选择具有最高强度参数的接头。此外，还测试了各类型带的拉伸强度。对TPU薄膜的连接方法进行了验证。获得的结果使我们能够确定，TE324材料最强的连接方式是直的纵向十字缝合。这与实验室条件下测试的带中的载荷分布有关，也体现在它们的实际应用中。由于获得的结果，有可能选择最佳的连接（连接）方法和巴蒂chron的结构。
