Hyperboloid part ballast

The utility model discloses a hyperboloid part ballast belongs to aircraft static test field. Including rubber (1), billet (2) and iron -clad (3), iron -clad (3) have the recess, and are deviating from the one end of recess is provided with the auricle, the one end of billet (2) set to can with the surface assorted curved surface who has a curved surface of testpieces, the other end of billet (2) holds and is fixed in in the metal -clad recess, rubber (1) laminating sets up the one end that has a curved surface at billet (2). Exert pressure load on hyperboloid part surface through the device, accurate, stable, the continuity is good, has protected loading system and testpieces, has practiced thrift experimentation cost greatly. 本实用新型公开了种双曲面零件压载装置，属于飞机静力试验领域。包括胶皮(1)、木块(2)以及铁壳(3)，所述铁壳(3)具有凹槽，且在背离所述凹槽的端设置有耳片，所述木块(2)的端设置成能够与试验件的具有曲面形状的外表面相匹配的曲面形状，木块(2)的另端容纳并固定于所述铁壳的凹槽内，胶皮(1)贴合设置在木块(2)的具有曲面形状的端。通过该装置在双曲面零件表面施加压力载荷，准确、稳定，连续性好，保护了加载系统和试验件，大大节约了试验成本。
