提高試驗(yàn)平臺(tái)的使用命壽的方法

為使平臺(tái)提高它的使用壽命，保證它的工作精度，建議對(duì)刮研深度或控制在（0.02mm）以上，這樣可保證振動(dòng)實(shí)驗(yàn)平臺(tái)有著較長(zhǎng)的使用壽命和檢定周期。振動(dòng)實(shí)驗(yàn)平臺(tái)表面應(yīng)清除型砂、且表面平整，涂漆牢固,各棱邊應(yīng)修鈍。從使用的角度講，在不致引起工件與振動(dòng)實(shí)驗(yàn)平臺(tái)發(fā)生研合的情況下，盡可能提高接觸面積，可提高振動(dòng)實(shí)驗(yàn)平臺(tái)的使用壽命。
JJG117-91檢定規(guī)程也未對(duì)此項(xiàng)予以適當(dāng)限制。

在精度等級(jí)低于“00”級(jí)的鑄鐵平臺(tái)工作面上，對(duì)于直徑小于15mm的砂孔允許用相同的材料堵塞，其硬度應(yīng)低于周圍材料的硬度。
JJG117-91檢定規(guī)程對(duì)刮研深度沒有做出規(guī)定，這無疑是一種缺陷。

產(chǎn)品的刮研深度對(duì)震動(dòng)實(shí)驗(yàn)平臺(tái)使用壽命的影響是不可忽略的。

Ways to improve the life of the test platform

In order to improve the service life of the platform and ensure its working accuracy, it is recommended that the depth of the scraping or control be above (0.02mm), which ensures that the vibration test platform has a long service life and verification cycle. The surface of the vibration test platform should be cleaned of sand, and the surface should be flat, the paint should be firm, and the edges should be blunt. From the point of view of use, the contact area can be increased as much as possible without causing the workpiece to be combined with the vibration experimental platform, and the service life of the vibration test platform can be improved.

The JJG117-91 verification procedure also does not properly limit this item.

For cast iron platform working surfaces with an accuracy level lower than “00”, sand holes with a diameter of less than 15 mm are allowed to be blocked with the same material and their hardness should be lower than the hardness of the surrounding material.

The JJG117-91 verification procedure does not specify the depth of scraping, which is undoubtedly a defect.

The effect of the scraping depth of the product on the service life of the vibration test platform is not negligible.
