新型轮拖总装线用电动接车下线设备的应用

新型设备系一种应用于轮式拖拉机总装配流水线场合的电动安全接车下线设备,区别于之前国内外接车下线技术,既可以用于"宽幅板"总装线,也可用于"窄幅板"总装线,克服了之前宽幅板总装线制约生产节拍的瓶颈问题,有助于大幅提高其生产效率和产能。该设备的台面可以在任意六级高度位置"平升平降"、"倾转"和"倾转回位",满足多机型生产,且总装线末尾输送工序、接车下线工序和下一加油加水工序的拖拉机输送衔接可实现防撞车安全保障。

Bi criteria flexible assembly line design problem with equipment decisions

In this paper, we address the assembly line balancing and design problem of assigning tasks and equipment to work stations where there are several equipment alternatives for each task. We consider minimizing the total equipment cost and the number of work stations criteria. We aim to generate efficient solutions with respect to these criteria and propose a branch and bound algorithm whose efficiency is enhanced with powerful reduction and bounding mechanisms. We find that our algorithm is capable of solving problem instances with up to 25 tasks and five pieces of equipment.

Ballistic limit equation for equipment placed behind satellite structure walls

A new ballistic limit equation has been developed for the case of a Whipple shield configuration or a sandwich panel with honeycomb core placed in front of a backwall. This “triple plate” ballistic limit equation considers explicitly the thicknesses, materials and spacings of each of the three plates. The third plate, i.e., the backwall, represents the cover plate or external wall of the equipment that is placed behind the satellite structure wall. The ballistic limit equation has been calibrated with experimental results obtained from hypervelocity impact tests on satellite equipment that was placed behind typical satellite structure walls. The equipment considered were fuel and heat pipes, pressure vessels, electronic boxes, harness, and batteries, all representative of real satellite equipment. The new equation was applied to prove that if the inherent protection capability of satellite equipment against hypervelocity impacts is explicitly considered in a ballistic limit equation, the critical projectile diameters for failure of such equipment are raised considerably compared to the case where equipment is assumed to fail as soon as the structure wall that protects it is perforated.
