Development of topology optimization tool

普惠加拿大公司在加拿大拥有6,200名员工，在全球200个国家和地区拥有50,000台发动机，在为商务、通用航空和支线飞机和直升机提供动力的飞机发动机的设计、制造和服务方面处于世界领先地位(PWC，www.pwc.ca)。作为这样一个快速发展的市场的领导者，他们有持续改进的历史(和要求)。为了在这样一个要求苛刻的行业中保持强大的市场地位，产品设计和开发方面的创新至关重要。虽然坚固、轻便的产品对于任何行业来说都是理想的，但最大化性能和缩短设计时间的重要性被大大放大，特别是在飞机行业。拟议的项目旨在开发一种具有多学科设计优化工具的拓扑优化方法，以改善PWC发动机部件的特性，缩短设计和开发时间。作为第一个应用和测试案例，将使用拓扑优化方法对PWC发动机的缓冲集箱冷却器支架进行重量最小化。最终交付成果将包括优化的支架设计以及最终报告包，其中包括使用发动机部件多学科设计优化工具进行拓扑优化的方法。

With 6,200 employees in Canada and a fleet of 50,000 engines flying in 200 countries worldwide, Pratt & Whitney Canada is a world leader in the design, manufacture and service of aircraft engines powering business, general aviation ad regional aircraft and helicopters (PWC, www.pwc.ca). As a leader in such a rapidly evolving market, they have a history (and requirement) of perpetual improvement. Innovation in the product design and development is crucial in order to be able to maintain a strong market position in such a demanding industry. While the idea of strong, lightweight products is invariably ideal for any industry, the importance of maximizing performance and reducing design timeframe is amplified greatly particularly in the aircraft industry. The proposed project will aim to develop a topology optimization methodology with multidisciplinary design optimization tool that improves the characteristics of PWC engine components and shorten design and development timeframe. As a first application and a test case, weight minimization of a buffer header cooler bracket of a PWC engine will be conducted by using topology optimization. Final deliverables will include optimized bracket designs along with a final report package including a methodology for topology optimization with multidisciplinary design optimization tool for engine components.
