In order to solve the problem that parallel bus structure anti-harsh environment computer lack of computing performance, a design method of anti-harsh environment computer based on VPX is proposed. This method includes anti-harsh environment computer's design ideas and implementation of process. Simulation and test tools is used to ensure the accuracy of high-speed serial circuit design, water cooling ways is used to enhance the computer's cooling efficiency. After the design was completed, computer functions has been running for reliability test by software, critical high-speed signal is tested by the oscilloscope, the computer is stable and high-speed signal parameters meet key regulatory requirements in the test.%为了解决基于并行总线结构的抗恶劣环境计算机计算性能不足的问题,提出了一种基于VPX的高性能抗恶劣环境计算机的设计方法；该方法中包括基于VPX的高性能抗恶劣环境计算机的设计思路和实现过程；在该方法采用了仿真与测试的手段保证了高速串行电路设计的正确性,采用水冷散热方式提高了计算机的散热效率;在设计完成后,在实验室环境下通过测试软件对计算机的功能进行了可靠性测试,通过示波器对关键高速信号进行了测试,在功能测试中计算机运行稳定可靠,关键高速信号参数满足规范要求.
