Dynamic compaction machine is a powerful assistant in construction engineering, any excellent construction team must have the appropriate dynamic compaction equipment. So we have been using dynamic compaction machine on the construction site for a long time, regardless of wind and rain. How long is the service life of dynamic compaction machine? Do you know? The following editor will tell you about the life of the dynamic compaction machine:

强夯机在工作过程中会反复锤提升到一定高度，自动脱钩装置释放击锤或绳。在登陆锤和锤底过程的强周期性影响有一个强大的冲击波，影响机器的疲劳寿命，并直接影响强夯机的使用寿命，和生产成本，因此，疲劳寿命估计起着重要的作用，在强夯机的设计。

The dynamic rammer will repeatedly lift the hammer to a certain height in the working process, and the automatic decoupling device will release the hammer or rope. In landing hammer and hammer bottom process, the dynamic periodic influence has a strong shock wave, which affects the fatigue life of the machine, and directly affects the service life, safety and production cost of the dynamic compaction machine. Therefore, the fatigue life estimation plays an important role in the design of dynamic compaction machine.

疲劳破坏是一种捣固机故障的循环加载引起的疲劳失效的主要原因，往往是远小于峰值根据静态分析来估计“”的负荷。从整体上看，对强夯机疲劳问题的研究还处于实验探索阶段，还没有一个令人满意的理论解释的失效机理，只能得到一些规律，从宏观上。

    fatigue failure is the main cause of fatigue failure caused by cyclic loading of tamping machine failure, which is often far less than the peak value. According to the static analysis, the "safe" load is estimated. On the whole, the research on the fatigue problem of dynamic compaction machine is still in the stage of experimental exploration, and there is no satisfactory failure mechanism explained by theory.

  在传统的设计，在程序或详细设计阶段通常使用简单的计算是不真实的产品寿命估算的设计师，这些估计的寿命通常是通过物理样机的耐久性试验获得的，这不但试验周期长，成本高，以及相关的参数和许多失败之间的定量关系不能得到的测试，测试结果也可能是许多偶然因素。

In the traditional design, it is not true to use simple calculation in the process or detailed design stage. The estimated life is usually obtained through the durability test of physical prototype, which not only has a long test cycle and high cost, but also can not obtain the quantitative relationship between relevant parameters and many failures, and the test results may also be Many accidental factors.

虚拟疲劳设计是一个数字化的基于产品的计算机仿真模型的设计方法，应用计算机技术，视觉图像的虚拟样机仿真及疲劳寿命分析的虚拟环境。在虚拟样机疲劳寿命设计过程的早期阶段进行了分析，然后根据优化的结果，避免了设计的盲目性，提高物理样机试验的可能性，从而大大缩短产品开发周期。

Virtual fatigue design is a digital design method based on computer simulation model of products. It is a virtual environment for Virtual Prototype Simulation of visual images and fatigue life analysis. In the early stage of the fatigue life design process of virtual prototype, the blindness of design is avoided and the possibility of physical prototype test is improved according to the optimization results, thus greatly shortening the product development cycle.

因此，如何利用计算机技术，通过虚拟样机实现强夯机进行疲劳寿命，是一个重要而长期的任务。

Therefore, it is an important and long-term task to realize the fatigue life of dynamic compaction machine by using computer technology and virtual prototype.
